It has often been claimed that Priestley was a skilful experimenter who lacked the capacities to analyze his own experiments and bring them to a theoretical closure. In attempts to revise this view some scholars have alluded to Priestley’s ‘synoptic’ powers while others stressed the contextual role of British Enlightenment in understanding his chemical research. A careful analysis of his pneumatic reports, privileging the dynamics of his experimental practice, uncovers significant yet neglected aspects of Priestley’s science. By focusing on his (...) early experimental conduct and writing on nitrous air, I demonstrate how his methodological and rhetorical devices, far from being consequences of compulsive writing or theoretical naïveté, were deeply entwined with his chemical research. I employ the notion of ‘style of experimental reasoning’ —derived from A. C. Crombie and I. Hacking—to shed light on the intersection at which Priestley’s unique method, literary style, and epistemology converged to generate scientific knowledge. Establishing Priestley’s SER advances a finer understanding of the interactive character of his pneumatic experimentalism, peculiar dimensions of which have evaded both traditional as well as revisionist scholarship, thus infusing the longstanding historiographic debate over his scientific merits.Keywords: Joseph Priestley; Eighteenth-century chemistry; Pneumatic research; Style of reasoning; Epistemology.

The ArgumentJohann von Justi, the foremost literary cameralist of his generation, served as chief police commissioner in Göttingen between 1755 and 1757. While in Göttingen, Justi offered lectures at the university on the “œconomic, police and cameral sciences.” He also arrested vagrants, wrote on chemistry, disciplined unruly students, conducted chemical experiments, supervised the pricing of Göttingen's staple goods, engaged in a public controversy with a prominent Berlin chemist, edited and published a bi-weekly periodical (Göttingische Policey-Amts Nachrichien), and worked with the (...) university's curator to refashion the academic structure of the sciences. Taken together, these various activities reflected his broad vision for social and academic change, a vision with important implications for the form and content of the sciences. Drawing on archival material in Göttingen, on articles from thePolicey-Amts Nachrichten, and on Justi's other cameralist and chemical writings, I use his everyday experiences as a local police official to explore the meaning of his chemical work. I argue that Justi's chemistry was suffused with the cameralist dreams and ambitions of a small-town police commissioner. It is what I call police chemistry. (shrink)

Over the last forty years several historians have drawn attention to aspects of the activities of lecturers on natural philosophy in Britain in the eighteenth century. Hans and others looked at the part these lecturers played in the development of education, particularly adult education. Musson and Robinson considered the possible connection between the work of the lecturers and the growth of industry, and Inkster and others have explored the relationship between lecturers and the institutions set up to support science, especially (...) around 1800.4 More recently, Schaffer has pointed to the parallels between the performances of the lecturers on natural philosophy and other contemporary cultural activities. As a consequence of these studies we know much more about the work of the lecturers, its significance, and, to a lesser extent, their relationship to their audience. (shrink)

The ArgumentThis article explores the relationship between Goethe's administration of the duchy of Saxe-Weimar-Eisenach and his investigation of nature. The notion of the budget was crucial to both enterprises. In Goethe's morphological and mining works, nature's budgets were a heuristic tool by which one could elucidate natural processes. Goethe applied his epistemological approach of investigating nature to the realm of social order. Law, order, balance, and budget formed the basis of Goethe's financial reform of the duchy. He tried, unsuccessfully, to (...) construct artificial budgets, which were intended to mirror natural budgets to guide his plans of reform. (shrink)
