'The Language of Mineralogy ranges far beyond the traditional canon of philosophical texts to fashion important new perspectives on the intellectual and social world of the Scottish Enlightenment. John Walker's multi-faceted life as a teacher, field naturalist, clergyman, and advisor and companion to powerful aristocratic patrons is a rich quarry that Matthew Eddy exploits with authority and elegance. His book brings to centre-stage the painstaking tasks of classification in which Walker excelled. In doing so, it sets systems of natural history as a matter of central concern at the fertile interface between chemistry and mineralogy within the Edinburgh Medical School. As Eddy shows, such systems were anything but the static impediments to creative thought that they have too often been taken to be. The rehabilitation they receive in this book is long-overdue. This is cultural history of a high order.' Professor Robert Fox, University of Oxford 'In this detailed study of the scientific career of John Walker, Professor of Natural History at the University of Edinburgh in the late eighteenth century, Matthew Eddy has created a rich intellectual and social tapestry that greatly enhances our understanding of the scientific mindsets and activities of the Enlightenment. Eddy uses Walker's principal scientific interest in mineralogy to illustrate the relations and interactions between different sciences of the time, such as chemistry, medicine and geology. He also provides a detailed study of the commercial, industrial, social and cultural contexts of Walker's science and shows concretely how Walker participated in the international scientific 'republic of letters'. Eschewing retrospective "Whig" evaluation enables Eddy to present and analyze Walker's scientific theories and practices in mineralogy and geology with great historical empathy. We really get to feel what the sciences of chemistry, mineralogy and geology were like in the era before the triumph of Lavoisier, Lyell and Darwin.This book should be of interest to anyone working in Enlightenment cultural studies, in particular the Scottish Enlightenment, the history of chemistry, mineralogy and geology, and the history of modern science in general.' Seymour Mauskopf, Duke University, USA 'Eddy's reconstruction of the chemical basis of Walker's mineralogy and its importance to early geological ideas helps to rescue our understanding of eighteenth-century thinking about the earth sciences from Victorian "back-projections," from the tyranny of, as he puts it, "the various revolution models that still influence the history of science, philosophy and even culture"... The Language of Mineralogy offers carefully researched and well-considered insights into the practice of mineralogical classification, and its theoretical and institutional contexts, in eighteenth-century Scotland and beyond. Matthew Eddy makes a significant contribution to a more detailed and carefully contextual understanding of the natural history sciences of the Enlightenment.' David P. Miller, Isis '... any historian interested in broadening his or her knowledge of Enlightenment-era classification and any historian of chemistry convinced that the period between Boyle and Lavoisier - when chemistry of fluids and principles dominated in practice - deserves more focused study will profit from Eddy's text and helpful appendices.' Bulletin for the History of Chemistry '[A]n important study of the methods used to order the earth so that its products might be made intelligible, here in medicine, to enlightened audiences, initially students, who would take these ideas into different social and intellectual communities. It is thus-perhaps surprisingly, given the intrinsic nature of the subject matter-an engaging account of the ways in which earth knowledge was made useful, of the importance of collecting and observational practices, and of work in the field and in the classroom... it ought not to be overlooked by all those interested in the ways in which ideas were taught, discussed, and categorically placed before being, if ever they were at all, printed and patronized by enlightened others.' Charles Withers, University of Edinburgh, in Eighteenth-Century Scotland 'Matthew D. Eddy succeeds in making a significant contribution to [the] recent and more nuanced approach to post-Kuhnian history of science... Students of eighteenth-century Scottish culture and medicine will find much of value here, as will students of eighteenth-century geology and chemistry.' American Historical Review '... Eddy has done a magnificent job in further clarifying the puzzling and fascinating development of the history of chemistry from its alchemical beginnings. His portrayal of the rich interdisciplinarity of early modern natural history, chemistry, and natural philosophy is an important addition to the field...' Journal of British Studies 'It is thus with great pleasure... that I read Matthew Eddy's polemically (semi-)biographical study of John Walker, professor of natural history at the University of Edinburgh's medical school from 1779 to 1803. While most of Eddy's book reads quite easily, his argument is complex in terms of both its historiographical import and the many facets of its composition and historical implications... I take it as a sign of a good book that at the end the reader wishes to pursue its inquiries further. In The Language of Mineralogy, Eddy - so generous here with creative ideas for future research - has given us just this kind of book.' Lissa Roberts, British Journal for the History of Science 'Eddy's work is of value for anyone interested in the historiography of science, scientific pedagogy, the role of philosophy of science in historical narrative, or the Scottish Enlightenment. For students, there are also useful reflections on the effective use of archival sources as well as signposts for future research and suggestions for new approaches to the histories of mineralogy, geology, and chemistry. ... Eddy seems to have mastered the art of satisfying those readers who want their history of science to include as much of the detail of the science as possible, as well as those who prefer to reflect on the more sociological or philosophical aspects of the environment in which it was practised.' Georgette Taylor, Ambix 'The Language of Mineralogy is a significant contribution to the history of the earth sciences. It should be of primary interest to historians of eighteenth-century science: in particular, geology, mineralogy, chemistry and medicine. This welcome addition to eighteenth-century scholarship will certainly prove useful to historians of the Enlightenment and of early modern natural history and material culture.' Victor D. Boantza, Annals of Science
