Lead mining in the Yorkshire Dales

Bunting level: building, level entrance and hush

On a recent trip to the Yorkshire Dales we came across the remnants of lead mining; as with many things in the field these are blank discoveries with no indication of what they mean at the site. A very long time ago I did an OA level in geology, and I seem to have inherited an interest in industrial archaeology, so I resolved to find out more...

Lavoisier: Chemist, Biologist, Economist

Lavoisier

Recently I read Vivian Grey’s biography of Lavoisier. Although a fine book, it left me wanting more Lavoisier, so I turned to Jean-Pierre Poirier’s more substantial biography: “Lavoisier: Chemist, Biologist, Economist”. Related is my blog post on the French Académie des Sciences, of which Lavoisier was a long term member, and senior, member.

This is a much longer, denser book than that of Grey, with commonality of subject it’s unsurprising that the areas covered are similar. However, Poirier spends relatively more time discussing Lavoisier’s activities as a senior civil servant and as an economist.

The striking thing is the collection of roles that Lavoisier had: senior member of Ferme Générale (commissioned Paris wall), director of the Académie, director of the Gunpowder and Saltpeter Administration, owner and manager of his own (agricultural) farms. It’s difficult to imagine a modern equivalent, the governor of the Bank of England running a research lab? Or perhaps an MP with a minor ministerial post, running a business and a research lab? In practical terms he did experimental work for a few hours each morning and evening (6-9am, 7-10pm) and on Saturdays - having a number of assistants working with him. 

Lavoisier was wealthy, inheriting $1.8million* from relatives as an 11 year old he joined the Ferme Générale with an initial downpayment of about $3million. However, this provided an income of something like $2.4-4.8 million a year. On a trip to Strasbourg as a 24 year old, he spent $20,000 on books – which you have to respect. As the collector of taxes levied on the majority but not the nobility or clergy, the Ferme Générale was one of the institutions in the firing line when the Revolution came. Wealthy financiers, such as Lavoisier, bought stakes in these private companies, provided exclusive rights by the King, and made enormous rates of return (15-20%), at the same time serving the Kings needs rather poorly.

As for his activities in chemistry, Poirier provides a a good background to the developments going on at the time. Beyond what I have read before, it’s clear that Lavoisier does not make any of the first discoveries of for example, oxygen, carbon dioxide or nitrogen, nor of the understanding that combustion results in weight gain. But what he does do is build a coherent theory that brings all of these things together and overthrows the phlogiston theory of combustion. With Guyton de Morveau he develops a new, systematic, way of naming chemicals which is still used today and, as a side effect, embeds his ideas about combustion. It’s from this work that the first list of elements is produced. Furthermore, Lavoisier sees the applications of the idea of oxidation in explaining “chemical combustion” as entirely appropriate for understanding “biological combustion” or respiration. In a sense he sets the scheme for biochemistry which does not come to life for nearly 100 years, for want of better experimental methodology.

It’s interesting that gases are arguably the most difficult materials to work with yet it is their study, in particular understanding the components of air, which leads to an understanding of elements, and the “new chemistry”. Perhaps this is because gases are their own abstraction, there is nothing to see only things to measure.

The book also gives a useful insight into the French Revolution for someone who would not read the history for its own sake. The heart of the Revolution was a taxation system that exempted the nobility and the clergy from paying anything, and a large state debt from supporting the American War of Independence. Spending appears to have been decided by the nobility, or even just the King, with little regard as to how the money was raised. At one point Paris considered an aqueduct to bring in fresh water to all its citizens, but then decided that rebuilding the opera house was more important! The Revolution was a rather more drawn out than I appreciated with Lavoisier at the heart of the ongoing transformation at the time of his execution during the Terror, only to be lauded once again a couple of years later as Robbespierre fell from power and was executed in his turn.

On economics: Lavoisier was one of the directors of the French Discount Bank, during the Revolution he was involved in plans for a constitutional monarchy and amongst the ideas he brought forward was for what would essentially be an “Office for National Statistics”. The aim being to collect data on production and so forth across the economy in support of economic policy. This fits in with the mineral survey work he carried at the very beginning of his career and also on his work in “experimental farming”. Economic policy at the time alternating between protectionism (no wheat exports) and free-markets (wheat exports allowed), with many arguing that agriculture was the only economically productive activity.

It’s tempting to see Lavoisier’s scientific and economic programmes being linked via the idea of accounting: in chemistry the counting of amounts of material into and out of a reaction and in economics counting the cash into and out of the economy. 

Definitely a book I would recommend! It’s remarkable just how busy Lavoisier was in a range of areas, and the book also provides a handy insight into the French Revolution for those more interested in science. I wondering whether Benjamin Franklin should be my next target.

The naming of things

This post is a response to one of the points Rebekah Higgit makes over at “Whewell’s Ghost” on “Dos and Don’ts of history of science”. It’s all about scientists:

1) Do not ever call anyone a scientist who would not have recognised the term. The word was not coined until the 1830s (by William Whewell himself) but a) he meant something rather different by it and b) the word was not actually used until the 1870s. If we use the term to describe anyone before this date we risk loading their views, status, career, ambitions and work with associations that just do not exist before this date.I may know what I mean if it slips out in my description of an 18th-century astronomy, but the person listening to me will hear all sorts of other things. It too easily glides over points such as the fact that individuals probably did something else to make their living, or were personally wealthy. Science was not a career, or a vocation. I could give many further examples, and expand this rule into to using actors’ categories elsewhere, but this is the fundamental point. Not only did the word not, essentially, exist pre-1870 but there was no equivalent and no such idea. Awkward as it can sometimes be, man of science, natural philosopher, mathematician, astronomer, physician, naturalist or whatever should always be used instead.

I disagree with this. I should point out that I don’t consider this a Marmite* argument: the point Rebekah makes is not unreasonable and arguing serves to reinforce the point she is making. That the lives of “scientists” in the past were very different from the lives of most modern “scientists” is an entirely fair point, and is perhaps what the history of science is all about.

Since Rebekah is a professional historian of science, I feel my best approach is to argue this point on linguistic and scientific grounds, since I am a scientist not a historian. The OED says a scientist is:

  1. A person with expert knowledge of a science; a person using scientific methods.

it goes on to describe its coining via almost joking discussions over the British Association for the Advancement of Science in 1834 to Whewell’s use in 1840.

Precluding the use of the word “scientist” from application to people living before it was introduced seems to rather limit our options – how far must this sanitisation of language extend? Our use of words evolves in time. There are parallels here with Maxwell’s equations: in the mathematical language of his time his equations were clumsy and verbose, in more modern notation they are much more compact (and to overuse a word “elegant”). Working scientists don’t use Maxwell’s original notation, they use the modern notation because it captures the essential elements of the original work but is easier to use.

In my view the heart of the issue is the way in which we define scientists, to me being a scientist is defined operationally: by what I do in applying the scientific method, and by inference what people did in the past. Rather than socially or economically: what I have been trained to do or what people would pay me to do. I would still be a scientist if I were not paid for it, and hadn’t been trained. In both cases I might be poorer, but in different senses of the word!

There is also a point about communication here too: using a word for which you and your colleagues hold a specialist, narrow meaning may be “correct” but not help with communication. Knowing that your definition and the definition your audience hold is different is important but does not mean you should hold your definition sacrosanct – I face the same issue communicating my specialist area of science.

Perhaps the issue here is that Rebekah takes scientist to mean “modern professional scientist” whilst my definition is more catholic.

This does lead to the question: should I describe myself as a historian?

*Appropriate here since I work for the company that makes Marmite.

L’Académie des Sciences

ColbertPresents

I’ve written a number of times on the Royal Society, Britain’s leading and oldest learned society, often via the medium of book reviews but also through a bit of data wrangling. This post concerns the Académie des Sciences, the French equivalent of the Royal Society. It has gone through several evolutions, and is has been one of five academies inside the Institut de France since its founding in 1795. As a physical scientist the names of many members of the Académie are familiar to me; names such as Coulomb, Lagrange, Laplace, Lavoisier, Fourier, Fresnel, Poisson, Biot, Cassini, Carnot …    

The reason I’m interested in scientific societies is that, as a practitioner, I know they are part of the way science works – they are the conduit by which scientists* interact within a country and how they interact between countries. They are a guide to who’s hot and who’s not in science at a particular moment in time, with provisos for the politics of the time. As I have remarked before much of the “history” taught to scientists comes in the form of Decorative Anecdotes of Famous Scientists, this is my attempt to go beyond that narrow view.

The Académie des Sciences was founded in France in 1666 only a few years after the Royal Society which formally started in 1660. It appears to have grown from the group of correspondents and visitors to Marin Mersenne. In contrast to the Royal Society it was set up as a branch of government, directed by Jean-Baptiste Colbert who had proposed the idea to Louis XIV. The early Academy ran without any statutes until 1699 when it gained the Royal label. The Academy was based on two broad divisions of what were then described as mathematical sciences (astronomy, mathematics and physics) and “physical” sciences (anatomy, botany, zoology and chemistry) within these divisions were elected a number of academicians, and others of different grades. Numbers were strictly limited: in 1699 there were 70 members and even now there are only 236. Unlike the Royal Society, funded by member subscriptions, the Academy was funded by government – giving a number of generous pensions to senior academicians to conduct their scientific work.

The Academy avoided discussion of politics and religion, echoing the founding principles of the Royal Society, and was explicit in making links to foreign academics giving them the formal status of correspondent. This political neutrality was sustained through the French Revolution: although the Academy was dissolved for a few years at the height of the Terror and was subsequently reformed with essentially the same membership as before the revolution. Furthermore work on revising the French system of weights and measures carried on through the Revolution.

The Scholarly Societies Project has an overview of publications by- and about the Academy. The earliest scientific papers of the Academy appear in “Journal des Sçavans”, which commenced publication in 1665, shortly before the “Philosophical Transactions of the Royal Society” and therefore the earliest scientific journal published in Europe. From 1699 a sequence of work is published in “Histoire de l'Académie royale des sciences” until 1797.  Finally “Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences” has been published since 1835. Most of which are freely available as full-text digitized editions at Gallica (the French National Library).

The British government established the Longitude Prize in 1714, by act of parliament, to award the inventor of a simple and practical method for determining the longitude at sea. Subsequently Rouillé de Meslay invested a similar prize for the Academy, which commenced in 1720. This sequence of Academy prizes was awarded yearly to answer particular questions and alternated between subjects in the physical sciences and subjects in navigation and commerce. Those in commerce and navigation revolved around shipping: with questions on anchors, masts, marine currents and so forth. These prizes were open to all, not just members of the Academy. Subsequently the Academy became a clearing house for a whole range of prizes, these are described in more detail in “Les fondations de prix à l'Académie des sciences : 1714-1880” by E. Maindron.

In summary, although similar in their principles of supporting science, scientific communication and providing scientific support to the state and commerce the Royal Society and the Académie des Sciences differ in their internal structure and relationship with the state. The Academy being more closely aligned and funded by the state, certainly in formal terms, and rather more limited in its membership.

In common with the Royal Society the membership records of the Académie are available to play with and in common with the Royal Society they are in the form of PDF files which are a real pain to convert back into nicely structured data. I could engage in a lengthy rant on the inequities of locking up nice data in a nasty read-only format but I won’t!

Book Review: The Chemist Who Lost His Head

Portrait_of_Antoine-Laurent_Lavoisier_and_his_wife
Following on from “The Measure of All Things” my interest in Antoine Lavoisier was roused, so I went off to get a biography: “The Chemist who lost his head: The Story of Antoine Laurent Lavoisier” by Vivian Grey. This turns out to be a slim volume for the younger reader, in fact my copy appears to arrive via the Jenks East Middle School in Tulsa. As a consequence I’ve read it’s 100 or so pages in under 24 hours - that said it seems to me a fine introduction.
Antoine Lavoisier lived 1743-1794. He came from a bourgeoisie family, the son of a lawyer, and originally training as a lawyer. Subsequently he took up an education in a range of sciences. As a young man, in 1768, he bought into the Ferme Générale which was to provide him with a good income but led to his demise during the French Revolution. The Ferme Générale was the system by which the French government collected tax, essentially outsourcing the process to a private company. Taxes were collected from the so-called “Third Estate”, those who were not landed gentry or clergy. Grey indicates that Lavoisier was a benign influence at the Ferme Generale, introducing a system of pensions for farmers and doing research into improved farming methods. Through the company he met his future wife, Marie Anne Pierrette Paulz, daughter to the director of the Ferme – Antoine and Marie married in 1771 when she was 14 and he 28. 
Lavoisier started his scientific career with a geological survey of France, which he conducted as an assistant to Jean Etienne Guettard between 1763 and 1767. This work was to be terminated by the King, but was completed by Guettard with Antoine Grimoald Monnet although Lavoisier was not credited. There seems to be some parallel here with William Smith’s geological map of the UK produced in 1815.
Through his geological activities Lavoisier became familiar with the mineral gypsum, found in abundance around Paris. He undertook a detailed study of gypsum which sets the theme for his future chemical research: making careful measurements of the weight of material before and after heating or exposure to water. He discovered that gypsum is hydrated: when heated it gives off water, when the dehydrated powder (now called plaster of Paris) is re-hydrated it forms a hard plaster. He wrote this work up and presented it to the Académie des Sciences – the French equivalent of the Royal Society, on which I have written repeatedly.
He was to present several papers to the Académie before being elected a member of this very elite group at the age of twenty-five, half the age of the next youngest member. Once a member he contributed to many committees advising on things such as street lighting, fire hydrants and other areas of civic interest, the Académie was directly funded by the King and more explicitly tasked with advising the government than the Royal Society was. Lavoisier was also involved in the foundation of the new metric system of measurement, which was the subject of “The Measure of All Things”. Lavoisier became one of four commissioners of gunpowder – an important role at the time. During his life he would have had contact with Joseph Banks – a long term president of the Royal Society, and also Benjamin Franklin – scientist and also United States Ambassador to France.
From a purely scientific point of view Lavoisier is best known for his work in chemistry: his approach of stoichiometry – the precise measurement of the mass of reactants in chemical reactions led to his theory of combustion which ultimately replaced the phlogiston theory. It is this replacement of phlogiston theory with the idea of oxidization that forms the foundation of Kuhn’s “paradigm shift” idea, so Lavoisier has a lot to answer for! 
The portrait of Antoine and Marie Laviosier at the top of the page is by Jacques-Louis David painted ca. 1788. It strikes me as quite an intimate portrait with Marie pressed against Antoine, looking directly at the viewer whilst her husband looks at her. Marie played a significant part in the work of Lavoisier, as well as recording experiments and drawing apparatus (something that takes good understanding to do well), and assisting with correspondence and translation  she was also responsible for publishing Mémoires de Chimie after his death. She was a skilled scientist in her own right. The equipment on the table and floor can be identified: on the floor is a portable hydrometer and a glass vessel for weighing gases. On the table are a mercury gasometer, and a glass vessel container mercury – likely illustrating the properties of oxygen and nitrogen in air. 
Antoine Lavoisier was executed in 1794, for his part in the Ferme Générale. His execution is attributed, at least in part to the ire of Jean-Paul Marat, who Lavoisier had earlier blocked from membership of the Académie des Sciences. It seems Lavoisier had been warned by friends that his life was in danger but appeared to think his membership of the Académie des Sciences would protect him. Ironically Jacques-Louis David also painted “The Death of Marat”.
100 pages on Lavoisier was not enough for me, I’m going for “Lavoisier” by Jean-Pierre Poirier next – some fraction of which appears to be available online, but I’m going for a paper copy.

Book review: The Scientific Revolution and the Origins of Modern Science

ScientificRevolution_JohnHenryThe book I review in this post is “The Scientific Revolution and the Origins of Modern Science” by John Henry. In contrast to previous history books I have read this is neither popular history of science, nor original material but instead an academic text book. My first impressions are that it is a slim volume (100 pages) and contains no pictures! Since childhood I have tended towards the weightier volume, feeling it better value for money.

The Scientific Revolution is a period in European history during which the way in which science was done changed dramatically. The main action took place during the 17th century with lesser changes occurring in the 15th and 18th centuries. The Royal Society, on which I have blogged several times, plays a part in this Revolution and God’s Philosophers by James Hannam is one view of the preamble to the period.

The book starts with a brief introduction to historiography (methods of history research) of the Scientific Revolution, with a particular warning against “whiggish” behaviour: that’s to say looking back into the past and extracting from it that thread that leads to the future, ignoring all other things - the preferred alternative being to look at a period as a whole in its own terms. History as introduced by scientists is often highly whiggish.

Next up is a highlighting of the Renaissance, a period immediately prior to the Scientific Revolution wherein much renewed effort was made to learn from the Classics, the importance of the Renaissance appears to have been in initiating a break from the natural philosophy and theology taught in the universities of the time, which were teaching rather than research institutions.

The Scientific Revolution introduced two “methods of science” which differentiated it from the previous studies of natural philosophy: mathematisation and experiment. Mathematisation in that for sciences particularly relating to physics the aim became to develop a mathematical model for the physical behaviour observed. Prior to the Revolution mathematics was seen almost as a menial craft, inferior to both natural philosophy and theology which relied on logical chains of deduction to establish causes. These days mathematics has a far higher prestige, as illustrated in this xkcd comicstrip. The second element of experimentation means the use of controlled experimentation rather than pure thought to determine true facts.

One of the more surprising insights for me was the influence of magic on the developing science, very much in parallel to the influence of alchemy on the developing chemical sciences: magic was a physical equivalent. Magicians were intensely interested in the mysterious properties of physical objects and were early users of lenses and mirrors. The experience they developed in manipulating physical objects was the equivalent of the experience the alchemists gained in manipulating chemicals. Some of this thinking went forward into the new science the remaining rump of bonkers stuff left behind.

It’s very easy to glibly teach of forces and atoms to students, or perhaps blithely demonstrate the solution to an, on the face of it, tricky integral. However, we take a lot for granted: the great names of the past were at least as intelligent as more recent ones such as Einstein or Maxwell yet they struggled greatly with the idea of a force acting at a distance and so forth and that’s because these ideas are actually not obvious except in retrospect. Mechanical philosophies of Descartes and Hobbes were amongst the competing ideas for a “system of the world” ultimately supplanted by Newton.

Henry highlights that most of the participants in the Scientific Revolution were religiously devout, as were many in that time. An interesting idea taken up, but now apparently rejected, was that Puritanism was essential in driving the Scientific Revolution in Britain. Despite this, it was in this period that atheism started to appear.

A few times Henry refers to differences in emphasis between the developing new science in Britain when compared to the Continent. In Britain the emphasis was on an almost legalistic approach with purportedly bare facts presented to a jury in the form, for example, of the fellows of the Royal Society – theorising was in principle depreciated. This approach originates with Francis Bacon, a former Attorney General and experienced legal figure. On the Continent the emphasis was different, experiments were seen more as a demonstration of the correctness of a theory. The reason for this difference is laid at the door of the English Civil War, only briefly passed when the Royal Society was founded. It is argued that this largely non-confrontational style arose from a need for a bit of peace following the recent turmoil.

In sum I found this book an interesting experience: it’s very dense and heavily referenced. Popular history of science tends to revolve around individual biography and it’s nice to get some context for these lives. I’m particularly interested in following up some of the references to other European learned societies.

Book review: God’s Philosophers

God_the_Geometer I seem to be on a run of book reviewing at the moment, as I’ve indicated before these are as much for me as they are for you! This weeks contribution is on “God’s Philosophers: How the Medieval World laid the foundations of Modern Science“ by James Hannam. This book looks at the development of science, or at least a precursor to modern science, during the Middle Ages (5th-15th century). This fits in with my previous book reviewing which has gone back to the founding of the Royal Society (1662), and a little earlier with Gerard Mercator (1512-1594).

To my mind the book makes a poor start in the introduction by telling me how everything I believe about the Middle (or Dark) Ages is wrong, and so is everyone else. I’m prepared to accept that my visualisation of the Dark Ages, as being quite literally Dark with peasants fumbling around in a permanent twilight may be wrong, however this type of introduction generally leaves me believing that the writer is a conspiracy theorist!

A recurring theme of the book is how those studying natural philosophy (a convenient term for the proto-science) continually ran the risk of being accused of heresy. Hannam seems to portray the treatment of heresy as not really so bad: only 1 in 20 trials resulted in burning at the stake, there wasn’t much torture, the victim was asking for it, the church handed over the heretics to the secular authorities who carried out the most terrible punishment. This seems to treat lightly the death, by burning at the stake, of people who simply believed something different. Perhaps more insidiously anyone studying natural philosophy had to have an eye to what the church believed in case what they studied was considered to be heretical. Later Hannam’s defence turns out to be more narrowly defined: he sees himself as defending the Catholic Church against Protestants. He reserves a special ire for humanists, those in the Renaissance who had a particular fondness for studying the ancient classics.

This said, the book is a nice overview of the development of the academic life after the fall of the Roman Empire, with the early universities in Italy and France growing up as offshoots from the great cathedrals. The very earliest of these institutions taught law, and sometime later medicine although the core of early teaching was in theology. A great deal of effort was expended in recovering the work of the Ancients (Greek philosophers) this was made difficult by the absence of much knowledge of Greek in Western Europe. The Arabs had picked up much of this material in an earlier period but translated it into Arabic rather than Greek whilst Western Europe had Latin as a common scholarly language. Interest was primarily in Aristotle, although later the works of Plato were re-discovered. In some ways it’s this aspect of the Middle Age and Renaissance enterprise which is so confusing to a modern scientist. It just looks like it would be far easier, and quicker, to make a fresh start and discover things for yourself rather than dredge through ancient, partial manuscripts in ill-known languages for clues.

There are various places in the book where I can feel myself trying to shout back through the ages “Yes, yes, you’re on the right track, keep going!”. Only to see the protagonist draw back at the last minute or for their work to be subsequently ignored. Examples include Nicole Oresme (1323-1382) and his use of graphs in understanding physical ideas. Or the theory of impetus developed by Jean Buridan (~1300-1358), which is a very direct precursor of modern theories of mechanical motion. Similarly isolated sparks spoke of doing controlled experiments to test theories, and the idea that mathematics could be used to describe physical processes. However these ideas did not seem to start drawing together until the period in which Galileo lived (1564-1642).

The part that astrology played in the development of astronomy is rather illuminating, as part of their programme the astrologers wanted to known exactly where heavenly bodies would be at some point in time in the past or future therefore they expended considerable, skilled effort in measuring the locations of these bodies and building models from these measurements. This was the work that lead Copernicus to propose a heliocentric solar system, and would have fed into Newton’s work on gravity, and all done for completely ridiculous reasons. This also highlights some of the oddities in the thinking of the early pioneers of the modern period, for example William Gilbert, who did excellent work on magnetism did it in a distinctly odd framework – he believed the magnet was the soul of a planet, similarly William Harvey’s work on the circulation of blood and Isaac Newton’s obsessive alchemy and bible study.

During the Middle Ages there were various technological developments: the mechanical clock (Norwich, 1273), spectacles (Venice, 1300), modern printing (by Gutenberg around 1439). Paper making had been brought to Europe at some time before 1276 when the first paper mill is recorded in central Italy. Gunpowder was first mentioned in Europe by Roger Bacon (1267), having been invented in China in around the 9th century. These inventions largely arose outside of the university system.

The book ends with the death of Galileo in 1642, who had been subjected to a trial for heresy following which he was held under house arrest for the remainder of his life. The book makes clear, that in common with Newton, Galileo was “standing on the shoulders of giants” drawing heavily on work in the Middle Ages – although synthesising into a coherent whole, making his own additions and also covering a large range of topics over his lifetime.

Finally there is a timeline, a cast of characters and a nice, manageable set of further readings.

I feel ambivalent about this book, the historical aspects of it I found very interesting, the proselytising less so. It seems evident that there was progress in proto-science during the Middle Ages, and also in technology. Hannam claims that the Catholic Church facilitated this progress; the evidence he presents is mixed – they supported scholarship and the founding of universities but simultaneously ran a system of Inquisition to detect heresy which made free academic enquiry difficult.

Early reports of the Royal Society

In an earlier post I wrote about Thomas Sprat’sHistory of the Royal Society of London, for the improving of Natural Knowledge“. Published in 1667, under the direction of the Royal Society which had first met in 1660, receiving their royal charter in 1662. In that post I deferred discussion of a selection of the early reports of the Society that were embedded in the History, for reasons of space.

The reports by title are these:

  • Answers returned by Sir Philberto Vernatti (Resident of Batavia in Java Major)
  • A Method for making a History of the Weather by Mr Hook
  • Directions for the Observations of the Eclipses of the Moon by Mr Rooke
  • A Proposal for Making Wine by Dr. Goddard
  • A Relation of the Pico Teneriffe
  • Experiments of the Weight of Bodies increased in the Fire by Lord Brouncker
  • Experiments of a Stone called Oculus Mundi by Dr Goddard
  • An account of a Dog dissected by Mr Hook
  • Experiments of the Recoiling of Guns by Lord Brouncker
  • The History of the Making of Salt-Peter and The History of Making Gunpowder by Mr Henshaw
  • An Apparatus to the History of the Common Practices of Dy[e]ing by Sir William Petty
  • The History of the Generation and ordering of Green Oysters Commonly called Colchester-Oysters

Interspersed amongst them Sprat adds in various brief comments on other work of the Society along with what amounts to a personal eulogy to Christopher Wren, who seems to have been involved in pretty much everything although Sprat seems to have been generous in attributing to Wren work which was largely done by other people.

Looking first at the authors: of Sir Philberto Vernatti I can find little, he appears to have been Governor of Batavia (now Jakarta) for the Dutch East India Company whilst most references I’ve found to him arise from this report to the Royal Society; Mr Hook was the first curator of experiments for the Royal Society and paid an important role in keeping the Society with interesting things to see, he was an outstanding scientist in his own right; Lord Brouncker was the first President of the Royal Society; Mr Rooke appears to have been Lawrence Rooke, who died in 1662; Dr Goddard is Dr Jonathan Goddard the early Society met in his lodgings at Gresham College, physician to Charles I and present at the death of Cromwell; Mr Henshaw is Thomas Henshaw an early Biological Sciences Secretary to the Royal Society; Sir William Petty was amongst other things an economist and a Parliamentarian in the Civil War. On the whole these reports look like they have been selected on political grounds, they are from the movers and shakers of the Society.

The contributions vary considerably in length and content, Dr Goddard’s proposal on making wine amounts to: “Do it in the West Indies using sugar cane”, similarly Mr Hooks account of dissecting a dog is very brief (it’s also pretty horrifying).

The reports on dyeing, oysters and the making of Salt-peter and gunpowder are quite detailed reviews of the current “state-of-the-art” in important trades, involving both references to previous literature and reports of current practice which read very much as if the authors had gone and observed the processes described. The answers returned by men in distant places: Sir Philoberto Vernatti in Batavia, Java and the report on the scaling of Pico Teneriffe are also very much directed to trade: does this wood grow well there? These are quite lengthy and range over quite a range of topics. From this it’s clear that the Royal Society wanted to be seen as contributing to the national wealth.

The reports by Hooke (on recording the weather), Rooke, Brouncker and Goddard (on Oculus mundi) are those which most closely resemble modern scientific papers. They report methods for conducting measurements, or the results of those measurements, unlike modern papers they do not draw strong conclusions from those measurements. In a sense they are following the scheme laid out by Sprat in which empirical measurement is important and theorising comes later. Oculus Mundi is a form of opal now known as hydrophane which goes transparent when it absorbs water, the OED reports that Sir Kenelme Digby had brought some of this material to the Society in 1661.

In sum it looks like the early Society was very busy. Much of what they wrote was very practical and aside from a comment on making insects from cheese and sack it largely looks quite sensible. In these reports I can see the origins of the primary scientific literature that I access as part of my work.

Book review: The History of the Royal Society of London by Thomas Sprat

NPG D11592, Thomas Sprat; Thomas Sprat In which I venture into original material, in the form of Thomas Sprat’sHistory of the Royal Society of London, for the improving of Natural Knowledge“. Published in 1667, under the direction of the Royal Society which had first met in 1660, receiving their royal charter in 1662. I must admit to having attempted to read this book a couple of times before and failed; the copy I have is a facsimile of the original therefore written in early modern English with heavy use of the “long s” inevitably leading to an internal voice with a pronounced lisp! It’s probably useful to replace “History” with “Prospectus” in the title, to satisfy modern tastes. Despite it’s age the writing style is surprisingly readable to my modern eyes.

Unlike any other book I have read the book starts with a dedication to the King, followed by a poem praising Francis Bacon (1561-1626). Bacon’s presence recurs throughout the book, Sprat clearly sees him as the intellectual godfather of the organisation. The book is divided into three sections; the first is a prehistory describing the state of natural knowledge before the Royal Society, the second section details the founding of the Society and the final section discusses the value of the knowledge the Society seeks.

The tour of prehistory is rapid; starting with the ancient priests who held knowledge to themselves, followed by the Greek philosophers (described as the Ancients) who Sprat feels were too fond of rhetoric in determining questions of knowledge and who he accuses of “hastiness”. The Romans receive relatively short shrift. Following the Roman Empire, Sprat sees the rise of the Church of Rome and a relatively barren period dominated by war, he cites here William of Malmsbury (1080-1143), an early English historian in support of this. He then bemoans the time spent by the Scholastics in what he considers pointless theology in the later period, presumably 1000-1500, William of Ockham falls into this group. Finally he comes to the recent era where he lists five groups involved in natural philosophising. Francis Bacon is cited reverentially once again, those taking on the philosophy of the ancients – tidying it up after it’s release from the abbeys in the Reformation, are less venerated. “Chymists” receive a mixed review with the more pedestrian welcomed but the alchemists, often seeking eternal life or some other fancy, are scorned. Isaac Newton, a later president of the Royal Society was a keen alchemist but by this time it was seen as not quite proper. He also comments on the coming of specialisation to different areas of science.

The founding fathers of the Royal Society started meeting in Doctor Wilkins lodgings in Wadham College, Oxford – it’s not stated explicitly when this started but it ended in around 1638 when the meetings moved to Gresham College in London. Sprat skims over the Civil War (1642-1651), although this period was clearly much on his mind in writing the book, then happily reports: “For the Royal Society had its beginning in the wonderful pacifick year of 1660”, the year of the Restoration when Charles II returned to the English throne. Sprat goes on to describe in some detail the guiding principles of the society, explicitly ruling out a teaching organisation citing the time required to do this and the potentially unhealthy Master-pupil relationship as damaging to the purposes of the Society. It is a principle of the new organisation that men of all religions and nations are welcome. This internationalism is a hallmark of modern science. Also highlighted is the idea that the Royal Society becomes a central repository for written information, the first of its kind. The Royal Society was funded from the subscriptions of it’s fellows, although they were open to public funding.

Sprat then provides a rather detailed description of how the Royal Society is constituted including how they go about their business in terms of doing and reporting experiments, I must admit to finding this a bit dull. It has the air of an organisational fanatic describing his perfect organisation, it’s questionable how closely the Royal Society managed to keep to this ideal. However, in his description of the processes of the Society we can see the genesis of the still used scientific literature, with the primary literature comprised of relatively short papers containing experimental results and theoretical developments based on those results. Charles II makes several appearances here, unsurprising given the recent granting of the Royal charter, but he also seems to have been moderately involved in the Society and had his own chemistry laboratory.

A substantial portion of the middle of the book is taken by a compilation of reports by the early Royal Society, these include:
  • Answers returned by Sir Philberto Vernatti (Resident of Batavia in Java Major)
  • A Method for making a History of the Weather by Mr Hook
  • Directions for the Observations of the Eclipses of the Moon by Mr Rooke
  • A Proposal for Making Wine by Dr. Goddard
  • A Relation of the Pico Teneriffe
  • Experiments of the Weight of Bodies increased in the Fire by Lord Brouncker
  • Experiments of a Stone called Oculus Mundi by Dr Goddard
  • An account of a Dog dissected by Mr Hook
  • Experiments of the Recoiling of Guns by Lord Brouncker
  • The History of the Making of Salt-Peter by Mr Henshaw
  • The History of Making Gunpowder
  • An Apparatus to the History of the Common Practices of Dy[e]ing by Sir William Petty
  • The History of the Generation and ordering of Green Oysters Commonly called Colchester-Oysters
I shall write on these reports in a separate post.
The book ends with a lengthy rebuttal of various criticisms of the Royal Society, including how “experimenting” is entirely compatible with the Christian religion and specifically the Church of England; this is perhaps unsurprising given Sprat’s occupation as a churchman. In addition to this there is the appeal that experimental philosophy as demonstrated by the Royal Society can benefit the nation by improving its industry and trade, including such things as importing plants across the emire. It also defends the interest of the nobility in this area, claiming that their country estates are the ideal places to conduct such studies, whilst the lower orders go off to fight wars!

Reading this book was an unusual experience for me. In contrast to the modern histories I more usually read I felt much more obliged to ask questions like: Why is this person writing this book? Why was Bacon so important? Is this some reverence to a politically important forbearer? Why the need for the book at all? A book length defence of such an organisation only 5 years after its formation seems a bit odd.

Reading this has given me a taste for contemporary material, I think I might have to look into Pepys and some original scientific publications.

Book review: The Map that Changed the World

william_smith_map_big These are some notes on “The Map that changed the World: The Tale of William Smith and The Birth of a Science” by Simon Winchester. It is the story of the creation, by William Smith, of the first geological map of England and Wales, and the first such map on this scale in the world. A geological map shows the distribution of different rock types on the earth’s surface. Sedimentary rocks are laid down in horizontal layers, known as strata, subsequently these layers may be deformed and distorted. Therefore the distribution of rock types on the surface is a slice this distorted underground structure. William Smith’s work went beyond simple mapping the surface by recording what went on under the surface.

William Smith was born in 1769, as the industrial revolution was getting under way. Enclosures, coal mining, canal building and drainage work were building blocks to Smith’s maps; as a young man he became involved in surveying as a result of enclosures around his birthplace of Churchill, near Oxford. Following this experience in surveying he became involved in coal mining in Somerset. Here he saw directly the strata beneath the surface and learnt their individual character. Then he was involved in surveying for a canal to link the Somerset coal mines to the main canal system. This combines surveying with geology, since the type of rock the canal goes over determines how easy it is to dig the canal and whether it leaks.

A key insight was that the fossils found within a strata could be used to exactly correlate two distinct outcrops – in the absence of fossils two outcrops might look very similar but actually belong to different strata. Secondly, strata always appeared in the same order: A always comes below B, which comes below C. In places, because subsequent distortion of the rock, this ordering may not be obvious. It was Smith who was responsible for “” which identified the order of strata occurring in England.

Fossils had become collectors items around the time of Smith’s birth. As a result of the increasing awareness of the fossils in the surroundings, sea animals many miles from the sea and fossils with no living counterparts, the biblical account of the creation of the earth was becoming increasingly shaky. In a sense it is geology that brought Darwin to his theory of evolution, the study of rocks makes it increasingly clear that the world is unimaginably old and that in this vast space of time there is room for evolution. In common with Darwin, Smith’s great work was a long time in preparation.

William Smith was dogged by financial problems, he had taken up a mortgage to buy a substantial estate whilst surveying for a canal and was then promptly sacked. Throughout his life he appears to have spent rather enthusiastically, sometimes simply to be seen as having an address in the right place. Ultimately William Smith went to debtor's prison for a short period in 1819, a few years after his map had first been published. On his release he moved to Yorkshire where he worked on various minor projects in obscurity. He was later returned to the public eye to receive the first Wollaston Medal from the Geological Society of London, along with the recognition he deserved. 

Earlier the Geological Society, under the presidency of George Greenough treated Smith shamefully: plagiarising a substantial chunk of his work on the geological map to produce their own version which was published not long after his, at lower cost. Furthermore they refused him admission to the society largely, it seems, on the basis of class. Smith had some previous experience of being plagiarised whilst in working in Bath, by a reverend! Although the subject of class arises a number of times through the book it doesn’t seem to have caused Smith huge impediment, aside from his initial contact with the Geological Society, throughout his life he worked with the landed gentry on various projects and it seems he was valued for this work. In addition he was apparently quite well known to Sir Joseph Banks – long time President of the Royal Society.

It’s striking that in addition to the Royal Society in London, the rest of the country was apparently riddled with philosophical societies, Bath is mentioned in particular in this regard but what really brought it home to me was mention of the Scarborough Philosophical Society, somewhere one wouldn’t now associate with such things.

The book is written in something of a docu-drama style with some sections reading a little like a novel, this is a mixed blessing to my mind – it enhances readability however it always leaves me with the fear that I’m being tricked into believing detail that doesn’t exist. I feel something of a connection to this work; I grew up on the Jurassic coast in Dorset (although this in a time before the marketing term had stuck) and did geology AO level whilst at school. It’s tempting to believe that England was the perfect spot for William Smith to be born: the geology of England is very varied and the industrial revolution provided a perfect excuse for detailed rummaging around in the rocks.

Science is Vital - history repeating 1667

I'm reading Thomas Sprat's "History of the Royal Society of London, for the improving of Natural Knowledge"* published in 1667. He's just mentioned that following the return of Charles II much spending has been made on public works and goes on to say:

This general Temper being well weigh'd; it cannot be imagin'd that the Nation will withdraw its Assistance from the Royal Society alone; which does not intend to stop at some particular Benefit but goes to the Root of all noble Inventions, and proposes an infallible Course to make England the Glory of the Western World.
This seems terribly relevant to current circumstances, he does spoil it slightly by going on to say:
There is scarce any Thing has more hindered the true Philosophy than a Vain Opinion, that men have taken up, that Nothing could be done in it, to any purpose, but upon a vast Charge, and a mighty Revenue.
 Old Sprat had a fine way with words!

Book Review: The Fellowship

an_experiment_on_a_bird_in_an_air_pump_by_joseph_wright_of_derby_1768 I’ve written previously about the Royal Society via the medium of book reviews: Seeing Further, Joseph Banks and Age of Wonder, and also in a data mangling exercise. This post is about “The Fellowship: The Story of the Royal Society and a Scientific Revolution” by John Gribbin, it describes the scientific world before the Society and the founding of the Royal Society. As with many books about this period, the front cover of my copy features “An experiment on a bird in the Air pump” by Joseph Wright of Derby and so that is the image I use to decorate this post. Following my usual scheme this review is really an aide memoire as much as a review.

The book opens with a set of brief biographies, starting with William Gilbert of Colchester (1544-1603), and his scientific study of magnetism: de Magnete (1600). This work on magnetism was unusual for it’s time in that it was very explicitly based on experimental observation, rather than the “philosophising” of Aristotelian school which imputed that the world could be understood simply by thinking. William Gilbert is relatively little known (ok – I didn’t know about him!), perhaps because his work was in a relatively narrow field and was superseded in the 18th century by work of people like Michael Faraday furthermore Gilbert seems to have spent most of his life practicing as a doctor with his scientific work playing only a small part of his life.

Next step is Galileo Galilei (1564-1642). He continued in the tradition of William Gilbert, eschewing the philosophical approach for experiment. In contrast to Gilbert, Galileo made contributions across a wide range of science for a long period – promulgating technology such as telescopes, microscopes and computing devices. This likely explains his greater fame. A detail that caught my eye was that as a professor of mathematics at the University of Pisa he was paid 60 crowns per year, whilst the Professor of Medicine gained 2000 crowns. For many early scientists, medical training appears to be the major scientific training available.

Francis Bacon (1561-1626) was more important as a parliamentarian, lawyer and courtier than a scientist. I link reluctantly to wikipedia in this instance, since in the opening paragraph they seem to be repeating the myth that he met his end through stuffing snow into a chicken to see if this helped preservation. His fame as a founding father of modern science is based largely on a book he didn’t write in which he intended to describe how a scientist should work – a scientific method. Perhaps more notably he had a vision as to how science might function in society at a time when there was no such thing as a scientist. It is apparently from Bacon that Isaac Asimov got his “Foundation”; it is the name of an organisation of scientific Fellows found in Bacon’s fictional work New Atlantis. Finally we are introduced to William Harvey (1578-1657), who identified the circulatory system for blood in the human body by a process of observation and experiment (published in De Motu Cordis (1628)) he was primarily a physician.

The point of this preamble is to say that, as the founding of the Royal Society approached, a number of people had started doing or proposing to do a new kind of science (or rather natural philosophy as it would have been called). The new natural philosophy involved doing experiments, and thinking about them – it was experimental science in contrast to the “received wisdom” from the ancient Greeks which was certainly interpreted to mean at the time that thinking was all that was required to establish true facts about the physical world. It’s not really accurate to say that one person did this and everything changed: rather that a shift had started to take place in the middle years of the 16th century. The foundation of the Royal Society can be seen as the culmination of that shift.

The Royal Society was founded at Gresham College in London on 28th November 1660, although it’s origins lay in Oxford where many of the group that would go on to form the Society had been meeting since the 1640’s. The Royal charter of the Society was agreed a couple of years later. The central figure in the Oxford group was John Wilkins (~1614-1672). The original Society included Christopher Wren, Robert Boyle and Robert Hooke amongst others. What striking is the political astuteness of the founding fathers as the monarchy returned to England in the form of Charles II, the first President, Viscount Brouncker, was a Royalist and the Society clearly identified that a Royal seal of approval was what they required from the very beginning. The Society had an air of purposefulness about it, not of airy philosophising for the amusement of gentlemen. The Society started publishing the worlds first scientific journal, “Philosophical Transactions”, and commissioning a history of their founding by Thomas Sprat only a few years later.  As a scientist I have picked out those names that mean most to me, however it’s very clear that the Royal Society was more than a group of scientists meeting to talk about science and the other less scientifically feted Fellows were equally important in the success of the Society.

Gribbin’s book then goes on to consider three men important in the early life of the Royal Society. Firstly: Robert Hooke (1636-1703), originally scientific assistant to Robert Boyle (1627-1691) who became the Society’s first “Curator of Experiments”. Prior to his appointment the Fellows appeared to be poorly organised in terms of providing weekly demonstration experiments for the Society’s education. Hooke was a really outstanding scientist, a skilled draftsman and maker of scientific equipment. The reason Hooke is not better known is largely down to Isaac Newton, with whom he had a longstanding feud and who outlived him. Newton (1643-1727) does not need further introduction as a scientist, his role in the Royal Society was to provide scientific gravitas (after Hooke had died) he was also President of the Society for the period 1703-27. Edmond Halley (1656-1742) was more important to the Society on the administrative side, he is chiefly remembered from the scientific point of view for his prediction of the return of a comet calculated using Newton’s theory of gravitation. He also spent a great deal of time persuading Newton to publish and trying to extract data from Flamsteed (the Astronomer Royal). In addition to this he invented a diving bell, wrote the first article on life annuities, published on the trade winds and monsoons, made observations of the stars of the Southern hemisphere and went on several scientific expeditions.

Some miscellaneous thoughts that arose as I read:
  • Royal patronage, in this instance by Charles II, was important for the Society in this period and later by George III – as described a little in Age of Wonder.
  • On the face of it astronomy is blue-skies research, but at the time the precise measurement of the position of the stars was seen as a route to determining the longitude - an important practical problem.
  • It’s notable that the persistent anecdotes about the scientists mentioned here i.e. Francis Bacon and the frozen chicken, Newton and the apple falling from the tree and Galileo dropping things from towers, originate from the earliest biographies often written by people who knew them personally. These anecdotes have later been found to be rather fanciful, but nevertheless have persisted.
  • There was serious feuding going between scientists in the early years of the Society!
Overall I enjoyed this book, although it does sometimes have the air of a collection of short biographies of men who are already relatively well known. The most interesting part to me was the core part around the founding of the Society, bringing in some of the lesser known members and also highlighting the importance of the non-scientific aspects of the Society in it’s success.

In terms of scientific history reading, where next? “God’s Philosophers” by James Hannam seems relevant to understanding scientific activities prior to those covered in this book. A deeper investigation into Edmond Halley seems worthwhile, and I should also make another attempt at the Thomas Sprat history of the Royal Society.

Book review: The World of Gerard Mercator


Once again I have been reading, this time "The World of Gerard Mercator" by Andrew Taylor. As before this blog post could be viewed as a review or, alternatively, as some notes to remind of what I have read. Overall I enjoyed the book, it provides the right amount of background information and doesn't bang on interminably about minutiae. I would have liked to have seen some better illustrations, but I suspect good illustrations of maps of this period are hard to come by and a full description of Mercator's projection was probably not appropriate.

The book starts off with some scene setting: at the beginning of the 16th century the Catholic church were still keen on Ptolemy's interpretation of world geography in fact to defy this interpretation was a heresy and could be severely punished. Ptolemy had put down his thoughts in Geographia produced around 150AD, which combined a discussion of the methods of cartography with a map of the known world. As a precedent Ptolemy's work was excellent, however by the time of the 16th century it was beginning to show it's antiquity. Geographical data, in Ptolemy's time, from beyond the Roman Empire was a little fanciful, and since the known world was a relatively small fraction of the surface of the globe the problems associated with showing the surface of a 3D object on a 2D map were not pressing. Ptolemy was well aware of the spherical nature of the world, Eratothenes had calculated the size of the earth in around 240BC, he stated that a globe would be the best way of displaying a map of the world. However, a globe large enough to display the whole world at sufficient detail would have to be very large, and thus difficult to construct and transport.

Truly global expeditions were starting to occur in the years before Mercator's birth: Columbus had "discovered"  the West Indies in 1492, John Cabot made landfall on the North American landmass in 1497. Bartolomeu Dias had sailed around the Southern tip of Africa in 1488, Vasco da Gama had continued on to India in 1497, around the Cape of Good Hope. The state of the art in geography could be found in Waldseemüller's map of 1507, showing a recognisable view of most of our world. Magellan's expedition would make the first circumnavigation of the globe in the early years of Mercator's life (1519-1522).

Mercator was born in Rupelmonde in Flanders on 5 March 1512, he died 2 December 1594 in Duisburg in what is now Germany at the age of 82. This was a pretty turbulent time in the Netherlands, the country was ruled by Charles V (of Spain) and there appears to have been significant repression of the somewhat rebellious and potentially Protestant population. Mercator was imprisoned for heresy in Rupelmonde in February 1543, remaining in custody until September, many in similar circumstances were executed, however Mercator seems to have avoided this by a combination of moderately powerful friends and a lack of any evidence of heresy.

Mercator's skill was in the collation and interpretation of geographical data from a wide range of sources including his own surveys. In addition he was clearly a very skilled craftsman in the preparation of copperplate engravings. He was commercially successful, manufacturing his globe throughout his life, as well as many maps and scientific instruments for cartographers. He also had a clear insight into the power of patronage.

His early work was in the preparation of maps of the Holy Land (in 1537) and Europe (in 1554), along with a globe produced in 1541. The globe seems to be popular amongst reproducers of antiquities, you can see details of it on the Harvard Map Collection Website.

Mercator is best known for his "projection", in this context a projection is a way of converting the world - which is found on the surface of a 3D sphere into a flat, 2D map. Mercator introduced his eponymous projection for his 1569 map of the world, illustrated at the top of this post. The particular feature of this projection is that if you follow a fixed compass bearing you find yourself following a straight line on the Mercator projected map. This is good news for navigators! The price you pay for this property is that, although all regions are in the correct places relative to each other, their areas are distorted so those regions near the poles appear much larger than those near the equator. Mercator seems to have made little of this discovery, nor described the method by which the projection is constructed - this was done some time later, in 1599, by Edward Wright. Prior to maps following Mercator's projection navigation was a bit hit and miss, basically you headed up to a convenient latitude and then followed it back to your destination - an inefficient way to plan your course. If you're interested in the maths behind the projection see here.

In terms of it's content the 1569 map shows Europe, Africa and a large fraction of Asia much as we would see it today, certainly in terms of outline. The Eastern coast of North and South America is fairly recognisable. The map fails in it's representation of the West coast of America - although to give credit where it is due, it at least has a west coast. The landmasses indicated at the northern and southern poles are close to pure fantasy. The Southern continent had been proposed by Ptolemy as a counterbalance to the known Northern continents - with no supporting evidence. Exploration of the far North was starting to occur during Mercator's life, with expedition such as that of Frobisher.

Mercator is also responsible for the word "atlas" to describe a book containing a set of maps, in this instance he coined the term to describe the volumes of maps he was preparing towards the end of his life, the last of which was published published posthumously by his son, Rumold, in 1595.

Following my efforts on Joseph Banks, I thought I'd make a map of significant locations in Mercator's life. You can find them here in Google Maps, zoom out and you will see the world in Mercator projection - a legacy from a man that lived nearly 500 years ago.

Book review: Joseph Banks by Patrick O'Brian

Once again I venture into my own idiosyncratic version of the book review: more reading notes than review. This time I'm reading the biography of Joseph Banks by Patrick O'Brian. Joseph Banks has popped up regularly in my recent reading about the Royal Society and the Age of Wonder. He was on Captain Cooks trip to Tahiti, and then went on to serve as President of the Royal Society for 42 years - the longest term of any President. The Inelegant Gardener has been reading about Kew and various plant hunters, and Sir Joseph crops up there too. Despite his many talents, there are relatively few biographies of Banks, and he is relatively unknown.

Sir Joseph was born of a wealthy family from Lincolnshire, he was educated at Harrow, Eton and then Oxford University. At some point in his school years he became passionately interested in botany, and whilst at Oxford he went to the lengths of recruiting a botany lecturer from Cambridge University to teach him. The lecturer was Daniel Solander, a very talented student of Carl Linnaeus, who would later accompany Banks on his trip around the world with Captain Cook, they would remain close friends until Solanders death in 1782.

Sir Joseph's first trip abroad was to Newfoundland and Labrador in 1766. The area had been ceded to Britain by France, but there was an international fleet of fishing boats operating in it's waters. Banks made his trip as a guest Constantine John Phipps on HMS Niger, which was sent to the area to keep an eye on things. It seems fairly common for gentleman to travel as guests on navy ships of the time: this was broadly the scheme by which Charles Darwin would later join HMS Beagle on his trip around the world.

1768-1771 finds Banks circumnavigating the world on Captain James Cook's ship, HMS Endeavour, in Cook's first such expedition. This voyage was funded by George III following an appeal from the Royal Society for a mission to Tahiti in order to observe the transit of Venus. Banks paid for the contingent of naturalists from his own funds. The stay in Tahiti is much written about largely, I suspect, because they remained there some time. Following their stay in Tahiti, they continued on to New Zealand, which they sailed around rather thoroughly but seemed to land on infrequently as a result of hostile responses from the inhabitants. They then sailed along the East coast of Australia, stopping off on the way at various locations but most particularly Botany Bay. At the time the the existence of Australia was somewhat uncertain in European minds. There's a rather fine map of their course here and Banks' journals are available here.

Through the chapters on both these voyages, O'Brian makes heavy use of the diaries of Banks, quoting from them extensively and often between block quotes further quoting Banks' own words. This may work well for those of a more historical bent, but I felt the need for more interpretation and context. It often feels that O'Brian is more interested in the boats than the botany.

The next episode is somewhat odd: Banks was planning a second trip around the world with Captain Cook but he never went. At almost the last minute he withdrew on the grounds that the Admiralty would not provide adequate accommodation for him and his team scientists. The odd thing is that, despite what appears a fractious falling out, Banks appeared to remain very good friends with both Cook and Lord Sandwich, First Lord of the Admirality at the time. I wonder whether Banks, remembering the 50% mortality rate of his previous voyage with Cook, understandably got cold feet. As a consolation he went off to Iceland in 1772 for a little light botanising, where he scaled Hekla.

Despite recording an extensive journal, collecting a considerable number of anthropological, botanical and zoological specimens as well as a large number of drawings by his naturalist team Banks never published a full report of his Tahiti voyage. He showed the artefacts at his home in Soho Square and prepared a substantial manuscript, with many fine plates but seems to have lost interest in publishing close to the end of the exercise. Throughout his life he produced relatively few publications, this may be a reflection of his dilettante nature: he was skilled in many areas but not deeply expert and so published relatively little.

Banks was elected to the Royal Society whilst on his world tour, and later become President for a 42 year term, until his death in 1820. He made some effort to improve the election procedures of the Society, at the time of his election being in the right social class appeared to be more important than being a scientist. As part of his role as President he was heavily involved in providing advice to government including a proposal to use Australia as a colony for convicts. He was also heavily involved in arranging the return of scientists and others caught up in the wars following the French revolution. In addition to his work at the Royal Society, he also helped found the Africa Association and the Royal Academy.

Kew gardens was created a few years before Joseph Banks became it's unofficial superintendent (in around 1773) and then director. He had a pivotal role in building the collection: commissioning plant collectors to travel the world, all backed by George III. I must admit that my recent reading has led me to see George III in a new light: as an enthusiastic supporter of scientific enterprises, rather than a mad-man. George III and Banks also collaborated on a programme to introduce merino sheep from Spain, which had potentially huge commercial implications. Banks was seen as a loyal courtier.

Through his life it's estimated that Banks wrote an average of 50 letters per week almost entirely in his own hand, although they were fantastically well organised during his life, on his death they were rather poorly treated and dispersed. Warren R. Dawson produced a calendar of the remaining correspondence. I've not found this resource online but a treatment like this Republic of Letters would be fantastic.

I suspect a comprehensive biography of Joseph Banks is exceedingly difficult to write; this one seemed to cover voyaging well but I felt was lacking in botany and his scientific activities at the Royal Society. Perhaps the answer is that a comprehensive biography is impossible, since he had interests and substantial impacts in so many areas. There was simply no end to his talents!

Seeing Further: A Blaggers Guide (Part 1)


I originally intended to describe this post as a book review, but really it isn't. It's a blagger's guide for those that haven't read the book in question, (Seeing Further: The Story of science and the Royal Society edited by Bill Bryson) or who have read it, but need reminding of the contents. If you want to read a proper review then I suggest Clare Dudman's review at Bookmunch.

Seeing Further is a collection of essays from a wide range of authors, all relating in some way to the Royal Society which celebrates it's 350th anniversary this year. I've read other work by most of the authors - they are all excellent.

Since I've written notes on each chapter this has become quite a long post, so I've broken it into two parts. Part two can be found here.

Bill Bryson starts things off with an introduction, providing a brief sketch of the history of the Royal Society and introducing a few of the distinguished fellows. His favourite is Reverend Thomas Bayes. Bayes' most important work was on probabilities, published two years after his death in 1761. Few will have heard of Bayes, but his work is central to modern statistics. I must admit this chapter made me curious as to the origins of other learned societies across Europe.

Then the fun begins with James Gleick, who has written excellent books on chaos and Richard Feynmann amongst many other things. He writes of the Society as an earlier version of the internet and the first place where people started recording and communicating observations systematically. They also conducted their own experiments. The international reach of the Royal Society was an essential component, managed effectively by it's first Secretary, Henry Oldenburg.  Perhaps wisely the fellows instituted a ban on discussing religion or politics.

Margaret Atwood writes about the development of the idea of the mad scientist as portrayed in the 50's B-movies. She sees the Royal Society, satirised by Jonathan Swift as the Grand Academy of Lagado in Gulliver's Travels, as the link between Dr Faustus and the modern mad scientist. Travelling by way of Mary Shelley's Frankenstein and Robert Louis Stevenson's Dr Jekyll and Mr Hyde.

These days it is broadly a given amongst scientists that the physical laws they determine here on earth extend throughout the cosmos. Margaret Wertheim writes on the genesis of this idea, the point when the boundary between heaven and earth was removed in mens minds and the heavens and earth started to be considered as a continuous whole, obeying the same physical laws. This transition had largely taken place prior to the formation of the Royal Society.

Neal Stephenson writes on Gottfried Leibniz and his monads. Stephenson is author of The Baroque Cycle, a historical science-fiction trilogy set around the time of the founding of the Royal Society with many of the early fellows featuring as characters. Monadology was Leibniz's philosophical program for understanding the universe, looked at with a modern eye one can see intriguing insights but ultimately our current understanding of the universe is quite distant from Leibniz's conception of monads. Nowadays it's recognised that Leibniz and Newton invented calculus independently and simultaneously, although Leibniz published first. The priority in this area was greatly disputed, with the Royal Society standing firmly behind Newton, latterly their President.

Next up is Rebecca Newberger Goldstein on how the establishment of the Royal Society marked the coming together of the rationalists, whom we would probably call theoreticians now, and the empiricists, or experimentalist in modern parlance. Contrasting these two more modern movements with the teleologists of ancient Greece who believed that the world was designed with a purpose and so their philosophical program was to identify the purpose of all things and the progress of those things towards their final ends. Although the teleologists observed, they tended to do so passively whilst the empiricists actively experimented: setting up nature to reveal underlying processes. The immediate precursors to the Royal Society were represented by empiricists such as  Francis Bacon, William Gilbert, and William Harvey and the rationalists represented by Nicolaus Copernicus, Johannes Kepler, Galileo Galilei and Rene Descartes. John Locke, Isaac Newton and Robert Boyle are cited as those at the forefront of the debate on what constitutes an explanation during the forming of the Royal Society.

Now for Simon Schaffer who tells a tell about the use of scientific advice for public policy development, and public dispute over that advice. The story is set around the tale of a lightning strike in Norfolk which struck the Heckingham House of Industry (a workhouse) on 12 June 1781, causing substantial damage. The building was protected by pointy lightning rods, as recommended by the Royal Society and the tale is of much internal bickering as to whether the lightning rods had been installed properly or whether the advice given by the Society was wrong. This was highly relevant at the time since, for example, you'd want to be really sure of your lightning protection if you ran an arsenal, full of gunpowder. Also interesting is who the fellows of the Royal Society trusted to give eye-witness statements: gentleman! Schaffer never really resolves the issue of the accuracy of the advice but highlights the parallels of this argument with modern arguments about evidence-based policy and how best to make recommendations based on science.

We move on to Richard Holmes, who writes about ballomania. This is the name coined by Sir Joseph Banks, recent president of the Royal Society, for the enthusiasm in France for balloons of both hydrogen and hot air during the 1780's. Outwardly Banks was dismissive of balloons, but in private he appears to have been keeping a close eye on developments. Ultimately the lack of navigability meant that interest in balloons waned. This chapter reminded me that Benjamin Franklin is someone of whom I need to know more, Franklin was Banks' correspondent in Paris where much of the balloon-y action was based. Another snippet, Aeropaedia, published 1786 records a balloon flight from my now home-town of Chester. Richard Holmes is the author of The Age of Wonder, on which I wrote earlier.

Richard Fortey is up next, author of Dry Store Room No. 1, which is about the Natural History Museum, given this background it's unsurprising that he writes about scientific collections. Well-curated collections of real objects are of critical importance to science. Fortey's chapter explains the role that the Royal Society played in setting up such collections, principally through the work of Sir Hans Sloane, a president of the society, whose collection was to form the basis of the Natural History museum via the British Museum. Sir Joseph Banks makes an appearance, for his work in setting up the Royal Botanical Gardens at Kew, as does Carl Linaeus father of taxonomy.

Richard Dawkins, who needs no introduction, writes on the claims for precedence in the discovery of evolution. It's relatively well-known that Alfred Russell Wallace spurred Charles Darwin into action by sending a manuscript to him which captured the core idea of evolution. Darwin's great achievement was the full length exposition of the theory, backed with experiments, in On the Origin of Species. Perhaps less well known are Edward Blyth, who believed that natural selection stabilised those species created by God (which is not really evolution) and Patrick Matthew, who mentions an idea of evolution quite similar to Darwin in the appendix of his book Naval Timber and Arboriculture but seems to have little idea of its significance.

Here endeth the first part of this review, feel free to get up and move around, perhaps have a cake and a coffee. Then move on to Part 2.
