Horizontal Chemistry.

In 1976 Raymond Williams commented, 'Culture is one of the two or three most complicated words in the English language.' Such implied difficulty has not prevented Bloomsbury Academic, since the 2000s, from publishing around forty series of their well-produced and generously illustrated Cultural Histories, with, according to their website, a further fifty in progress. Each series contains six volumes, each book covering, in theory, the same chronological period (antiquity, the Middle Ages, the Renaissance, the Enlightenment, the age of empire and the modern age), though there is some variation depending on precise topic. The idea is that one can use these books not only to read 'horizontally' about a subject across time, but also 'vertically' through different subjects in the same period - a idea made easier by the e-texts of the series on Bloomsbury's website.

When Ben met Mary: The Letters of Benjamin Thompson, Reichsgraf von Rumford, to Mary Temple, Viscountess Palmerston, 1793-1804.

This paper publishes the sixty-nine surviving very personal letters that Reichsgraf von Rumford wrote to Viscountess Palmerston after they met in Milan in 1793. The letters draw attention to the private domestic spaces of science and the critical importance of the aristocracy in scientific developments, topics that have both received some discussion recently. They were, however, not written with the purpose of providing historical evidence, but as part of a decade-long friendship which the letters trace, revealing, among other things, Rumford's other amours. They also describe in some detail his thoughts about his activities as a member of the governing elite in Bavaria, his scientific and engineering researches (especially the writing and publication of his Essays), as well as what he would have termed his philanthropic efforts in Bavaria, Northern Italy, Britain, and Ireland. All this is framed within the context of the Revolutionary and Napoleonic wars that in so many ways, directly and indirectly, affected Palmerston's and Rumford's lives and work.

A Chemical Satire on the 1809 Change of Government in Britain.

This note provides the context and transcription of a short satiric article published in the Bristol Mirror on the political events of 1809. The piece used chemical metaphors to provide an understanding of the circumstances surrounding the change of ministry in Britain in the autumn of that year. The article bears a strong resemblance to early twenty-first century political satire, including its relationship, or lack thereof, to reality.

Humphry Davy's Early Chemical Knowledge, Theory and Experiments: An Edition of His 1798 Manuscript, "An Essay on Heat and the Combinations of Light" from The Royal Institution of Cornwall, Courtney Library, MS DVY/2.

This paper publishes, for the first time, Humphry Davy's June 1798 "An Essay on Heat and the Combinations of Light" written in Penzance. It is the manuscript that he sent to Thomas Beddoes which secured for him the position of Superintendent of the Medical Pneumatic Institution in Bristol while aged only nineteen. It is thus a crucial document that increases our understanding about how Davy made that move from Cornwall to Bristol, without which it is highly unlikely that he would have followed the spectacular career trajectory that he did. The "Essay" provides new insights into Davy's very early chemical reading (especially the English translations of Antoine Fourcroy's Elémens d'histoire naturelle et de chimie), the extent to which Davy read this (and other texts) in French, the chemical apparatus he used, the experiments he made and the development and retraction of his theory of phosoxyd (later phosoxygen).

New Studies on Humphry Davy: Introduction.

This special issue of Ambix brings together eight new studies on Humphry Davy together with an appreciation of the life and work of David Knight, much of whose scholarship was devoted to understanding Davy. Taken together they provide a much richer and more nuanced account of aspects of Davy's life, showing how he and his work fitted into the very complex and difficult social, cultural and political contexts of the opening decades of the nineteenth century. Taking as our starting point Thomas Carlyle's 1829 critique of modern science, in this introduction we weld together the themes that emerge from these papers, many of which ground their results in the project to publish Davy's Letters. This project has provided evidence that helps us critique the disciplinary boundaries that led to Davy becoming seen mostly as a chemist, while his friend Samuel Taylor Coleridge has generally been categorised as a poet. Such boundaries are now breaking down fruitfully as these essays all illustrate in their different ways. A consequence of the new understandings being produced, is that we need to consider anew what constitutes chemistry and chemists, how reputations and commemorations are constructed, the role of audiences (especially women) in developing knowledge and the use of language and literature, which, among other things, are key elements linking chemistry with other parts of society and culture. Davy provides an excellent location by which to address the historical issues involved, giving us an opportunity to balance carefully these and other components (such as human agency) in understanding how knowledge is constructed.

Constructing Humphry Davy's Biographical Image.

This paper, which is also a contribution to the somewhat understudied area of the history of biography, discusses a couple of short accounts of Humphry Davy's life and the three major biographies published in the years following his death. These were an "anti-biography" by John Ayrton Paris (1831) and two admiring biographies by Davy's younger brother John Davy (1836, 1858). By examining the processes surrounding their writing and publication, this study illustrates how Davy's biographical reputation was constructed, how his surviving manuscripts and related documents came to be collected and preserved and so help us understand the effects they continue to exert on Davy scholarship.

"Agricultural Chymistry is at present in it's infancy": The Board of Agriculture, The Royal Institution and Humphry Davy.

In this paper I sketch the institutional interactions between the Board of Agriculture and the Royal Institution in the late eighteenth and early nineteenth centuries. This includes analysing the composition of memberships and committees of both bodies in which, inter alia, I challenge Morris Berman's account of their institutional relations. A key figure was Humphry Davy who, because of his career ambitions, occupied a slightly uncomfortable position as Professor of Chemistry to both organisations. Davy's lecture notebooks and his subsequent publication Elements of Agricultural Chemistry reveal that he drew almost all his direct knowledge of the subject from Britain and Ireland. Yet, despite such parochial shortcomings that might be expected of an infant science at time of war, the popularity of his book, particularly in North America, provided continuity between the end of the Board of Agriculture in 1822 and the start of the impact of Justus Liebig's work in the 1840s.
