Boantza Matter and Method in the Long CheMiCaL revoLution Science, technology and Culture, 1700–1945 Series Editors David M. Knight university of durham and Trevor Levere university of toronto Science, Technology and Culture, 1700–1945 focuses on the social, cultural, industrial and economic contexts of science and technology from the ‘scientific revolution’ up to the Second World War. It explores the agricultural and industrial revolutions of the eighteenth century, the coffee-house culture of the Enlightenment, the spread of museums, botanic gardens and expositions in the nineteenth century, to the Franco- Prussian war of 1870, seen as a victory for german science. it also addresses the dependence of society on science and technology in the twentieth century. Science, Technology and Culture, 1700–1945 addresses issues of the interaction of science, technology and culture in the period from 1700 to 1945, at the same time as including new research within the field of the history of science. also in the series Meeting Places: Scientific Congresses and Urban Identity in Victorian Britain Louise Miskell Matthew Boulton Enterprising Industrialist of the Enlightenment edited by Kenneth Quickenden, Sally Baggott and Malcolm dick Sir James Dewar, 1842–1923 A Ruthless Chemist J.S. rowlinson Matter and Method in the Long Chemical revolution Laws of another order viCtor d.

I cherish collaboration, especially with you [Lavoisier et al], your taste being so close to mine, but I would really like to connect in one system most if not all chemical phenomena and your theory cuts short all such hopes. It seems to me like a microscope that shows clearly certain aspects of objects close to us but leaves the more remote ones in complete darkness. The phlogistic system on the other hand resembles the natural view, showing the closer objects well enough while also encompassing the very distant ones. richard Kirwan in a letter to guyton de Morveau (november 1788) This page has been left blank intentionally Contents Series Editor’s Preface ix List of Figures and Tables xi Acknowledgments xiii Abbreviations xv Introduction 1 Historiography 1 Scientific Revolutions and Crises 6 Structure and themes 10 PART I: ChyMIsTRy In The sCIenTIfIC RevoLuTIon Duclos and Chymistry at the early Académie des sciences 1 Duclos Reads Boyle 27 The Crisis of Chymical Principles 30 The Origin and Form of Sweet Qualities 35 Duclos’s Principles 44 Particles of Saltpeter: Mechanism and Chymical Causality 48 On Boyle’s Unsuccessful Experiments 56 Conclusion 62 2 fire, Alkahest, and elements 67 Duclos’s Chymical Natural History of Plants 69 Dodart Enters the Arena: Natural History by Fire 76 radical analysis and the inner Life of Matter 83 Conclusion 91 3 from Cohesion to Gravity 93 the Causes of gravity 95 Forces, Big and Small: The Newtonian Context 99 The Causes of Coagulation: Chymical Operations and Mechanical Speculations 103 Conclusion 111 4 Interlude: The Crisis of Inter-Revolutionary Chemistry 115 viii Matter and Method in the Long Chemical Revolution PART II: CheMIsTRy In The CheMICAL RevoLuTIon 5 Priestley’s Quest for Airs and Ideas 145 Priestley’s Chemical Practice and Writing(s) 149 Experimental Commitments: The Case of Nitrous Air 153 Method, Text, and Epistemology 161 Conclusion 167 6 Pneumatic Metaphysics: scheele, Crawford, and Kirwan 171 Kirwan’s Work and Writings on Phlogiston 172 Phlogistic Transmutations and Pneumatic Metaphysics 179 the Phlogistic Constitution and role of heat 187 Kirwan enters the arena: innovations and renovations 195 Conclusion 205 7 operational uniformity and a “false shew of simplicity” 207 From Vapors to Facts 214 From Proportions to Quantities 223 The Force of Affinity and Affinity as a Force 227 From Uniformity to Simplicity 232 Conclusion 235 “Laws of Another order”: Concluding Remarks 237 Bibliography 241 Index 261 Series Editor’s Preface Most accounts of the history of chemistry, especially those written by chemists, have looked at the winners: and thus devoted much attention to Boyle, hailed as the founder of the science with his mechanical ideal and atomic (or corpuscular) basis; and Lavoisier, whose revolution brought a new understanding of combustion and a new terminology. victor Boantza, following an old maxim among historians, focuses upon the losers: Duclos, the critic of Boyle; Venel, who in Diderot’s great Encyclopédie promoted the idea that chemistry and physics were separate spheres; Kirwan, who became a convert to Lavoisier’s views; and Priestley, who isolated what Lavoisier and we call oxygen, but refused to give up belief in phlogiston. None of them were ignorant fuddy-duddies, and all had interesting things to say that illuminate how science works. Boantza as a result of his research has interesting things to say about revolutions, crises, and arguments in science; about the autonomy of sciences; and about the attempt to reduce one to another, supposedly more fundamental. duclos, a founder-member of the Paris académie des Sciences, saw Boyle as a physicist, ignorant of chemical traditions and practices, seeking to impose an oversimplified and useless program upon those who knew more about matter and its particularities than he did. Chemical processes like the coagulation of milk into cheese were wholly distinct from congelation, freezing, which was a physical and more superficial process. Chemists relied upon their senses, thought with their fingers, and gradually built up and generalized data: they did not need a revolution from above. Venel similarly saw the by-then-triumphant Anglo-Dutch Newtonians of the early eighteenth century in much the same light. the attractive forces of gravity and chemical affinity were completely different; and heat had both chemical and physical roles. Priestley was not simply a serendipitous discoverer of gases, but followed a systematic course of experimental discovery, each step opening new doors. He had little time for the barren elegance of Lavoisier’s algebraic deductive vision, his sophisticated apparatus, and his new terms: that was not what chemistry was about. Because Lavoisier’s terms prevailed, this study faces the difficult task of expounding the phlogiston theory in its various forms as new discoveries came in, and its defence by Kirwan and others for whom weights were not the be-all and end-all of chemistry, and who were well aware of the complexities of the material world. Phlogiston indeed took a long time to die because it still seemed to express an aspect of chemistry close to what we might anachronistically call chemical energy.
