With the advent of No 50 it was decided to amalgamate the earlier work and create a single index for all 50 issues. The work involved was a vast undertaking requiring the use of optical character recognition and other computer techniques on the earlier work, and a good deal of careful proof reading. The final product was handsomely produced in A4 size uniform with the Bulletin, running to 64 index pages. Having reached 80 issues, a similar combining exercise has been done, but with fewer categories within the Index. However, whilst the main index of individual topics remains as comprehensive as previously it is presented in a smaller typeface and makes use of more columns. At the time of printing, consideration is being given to the use of this new Index as a facility on the Society's website and also in connection with CDROMs of the Bulletin. Notes for using the 3 sections of the Bulletin Index, Issue No 1 to Issue No 80 Index of Topics Topics are arranged alphabetically by subject. References are shown as 'Issue No : Page No' eg 2:15 or 45:7-11 Index of Articles Authors of articles are listed alphabetically with the titles of their articles following in issue order. -

For one, ‘fieldwork has become the ideal type of knowledge’, so much so that much work in science studies asks not ‘about temporal priorities but about spatial coordination’.1 This agenda has been pursued empirically through study of European exploration in the eighteenth and nineteenth centuries. One of the key problematics for historians and geographers has been how, exactly, science collaborated with state actors to extend European nations’ ‘spatial grip’. There have been three common empirical responses to this question: through the deployment of physical observatories; through fieldwork; and by means of ships. Studies of observatories – on mountains, on the edge of oceans, in the polar regions – are many, as are studies of the ephemeral fieldsite.2 The ship has been seen to embody both of these types of scientific space. -

It focuses on attempts to transform Royal Naval log books into standardized meteorological registers that would be of use to both science and the state. The paper begins with a discussion of Admiralty Hydrographer, Francis Beaufort, who promoted the use of standardized systems for the observation of the weather at sea. It then examines the application of ships’ logs to the science of storms. The paper focuses on the Army Engineer, William Reid, who studied hurricanes while stationed in Barbados and Bermuda. Reid was instrumental in persuading the Admiralty to implement a naval meteorological policy, something the Admiralty Hydrographer had struggled to achieve. The paper uses the reception and adoption of work on storms at sea to reflect on the means and ends of maritime meteorology in the mid-nineteenth century. -
HISTORY of SCIENCE and TECHNOLOGY: SERIES THREE: Part 1, Babbage
HISTORY OF SCIENCE AND TECHNOLOGY: SERIES THREE: Part 1, Babbage THE HISTORY OF SCIENCE AND TECHNOLOGY Series Three: The Papers of Charles Babbage, 1791-1871 Part 1: Correspondence and Scientific Papers from the British Library, London Contents listing PUBLISHER'S NOTE BRIEF BIOGRAPHY BRIEF BIBLIOGRAPHY CONTENTS OF REELS LISTING BY CORRESPONDENT HISTORY OF SCIENCE AND TECHNOLOGY: SERIES THREE: Part 1, Babbage Publisher's Note “The idea of a digital computer is an old one. ... Babbage had all the essential ideas....” Alan Turing Alan Turing’s comment confirms the importance of Babbage to the History of Computing. Elected a Fellow of the Royal Society (aged 24) in 1816 - the same year in which Mary Shelley’s Frankenstein was written - Babbage showed that a machine could be created which could replicate certain areas of human thought. Babbage designed first the Difference Engine (an automatic mechanical calculating machine) and then the Analytical Engine (a pioneer digital computer). His designs included a central processing unit (“the Mill”), memory (“the Store”), variables, operators and a printer to output conclusions. The design was one thing, actually constructing the machines with the available technology proved to be extremely difficult. Notwithstanding substantial grants from the Royal Society and the British Government Babbage failed to create either. That glory was left to the Swedish printer, Georg Scheutz, who won a gold medal at the Paris Exhibition for constructing the Difference Engine. A close friend and collaborator in much of his work was Augusta Ada Byron, later the Countess of Lovelace, who was the only child of Lord Byron. She was confident of the importance of the machine, stating that “We may most aptly say that the Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves.” The metaphor was appropriate, for Babbage used a card reader inspired by the punched cards used on Jacquard loom. -
Charles Lyell to GA Mantell [ 5 February 1837 ]
147 Charles Lyell to G. A. Mantell [ 5 February 1837 ] My dear Mantell As soon as I received your letter I wrote to Sir John Herschell mentioning of course that I was not personally acquainted with Lieut Thomas but saying what you had said in favour of him & about him. His being an officer of Artillery is of itself a guarantee, at the same time then considering how many interruptions of the kind I know that Sir J. has, at the Cape, I told him fairly that there were very few for whom I would have done the service except for yourself, for I scarcely ever before ventured to introduce any one to any one, not being myself personally acquainted.1 I sent the letter to the address you mentioned & begged for an acknowledgement but have received none so I hope there is no mistake. I put 54 Harley St. & the M.P.’s name as directed, & had it miscarried I presume it would have been returned. Mr [Host?]2 brother-in-law of Murchison has I find been under your treatment & I was glad to hear that you had had much business at Brighton. He was afraid you were beginning to have the influenza yourself but I trust you escaped & have reaped the harvest which medical men are gathering in here. We have scarcely suffered but my clerk has been & is very ill. I am finishing my Anniversary Address for the 17th. inst. & shall tell you what Darwin has done in S. America. We have given 2 medals one to Capt. -

Editing Cavendish: Maxwell and the Electrical Researches of Henry Cavendish Isobel Falconer University of St Andrews
Falconer, ‘Editing Cavendish’, April 2015 Page 1 Editing Cavendish: Maxwell and The Electrical Researches of Henry Cavendish Isobel Falconer University of St Andrews Invited talk at the International Conference on the History of Physics, Trinity College, Cambridge, UK, in September 2014 Abstract During the last five years of his life, 1874-79, James Clerk Maxwell was absorbed in editing the electrical researches of Henry Cavendish, performed 100 years earlier. This endeavour is often assumed to be a work of duty to the Cavendish family, and an unfortunate waste of Maxwell’s time. By looking at the history of Cavendish’s papers, and the editorial choices that Maxwell made, this paper questions this assumption, considering the importance of Cavendish’s experiments in Maxwell’s electrical programme, and the implications that he may have derived for developing a doctrine of experimental method. Introduction In 1871 James Clerk Maxwell was elected to the newly established Chair of Experimental Physics at Cambridge, head of the new laboratory that William Cavendish, seventh Duke of Devonshire, had gifted to the University. Three years later, in 1874 Maxwell acquired the unpublished electrical papers of the Duke’s relative Henry Cavendish (1731-1810), and undertook to edit them for publication. Over the next five years, he devoted much of the time that he could spare from establishing the laboratory to transcribing and editing the papers. They were published in October 1879, the month before Maxwell died, in ‘a classic of scientific editing, -
Maxwell and Cavendish's Null Method for the Inverse Square Law Of

Please cite as: Falconer, I., No actual measurement … was required: Maxwell and p1 Cavendish’s null method for the inverse square law of electrostatics, Studies in History and Philosophy of Science (2017), http://dx.doi.org/10.1016/j.shpsa.2017.05.001 Released under Creative Commons CC BY NC ND No actual measurement … was required: Maxwell and Cavendish’s null method for the inverse square law of electrostatics Isobel Falconer School of Mathematics and Statistics University of St Andrews North Haugh St Andrews Fife UK KY16 9SS Email: [email protected] Abstract In 1877 James Clerk Maxwell and his student Donald MacAlister refined Henry Cavendish’s 1773 null experiment demonstrating the absence of electricity inside a charged conductor. This null result was a mathematical prediction of the inverse square law of electrostatics, and both Cavendish and Maxwell took the experiment as verifying the law. However, Maxwell had already expressed absolute conviction in the law, based on results of Michael Faraday’s. So, what was the value to him of repeating Cavendish’s experiment? After assessing whether the law was as secure as he claimed, this paper explores its central importance to the electrical programme that Maxwell was pursuing. It traces the historical and conceptual re- orderings through which Maxwell established the law by constructing a tradition of null tests and asserting the superior accuracy of the method. Maxwell drew on his developing ‘doctrine of method’ to identify Cavendish’s experiment as a member of a wider class of null methods. By doing so, he appealed to the null practices of telegraph engineers, diverted attention from the flawed logic of the method, and sought to localise issues around the mapping of numbers onto instrumental indications, on the grounds that ‘no actual measurement … was required’. -
