Two teaching chairs in chemistry were installed at the Jardin du Roi in Paris during the seventeenth century, and the lectures of Nicolas Lemery and Nicolas Le Fevre became standard texts for the next fifty years. 54 The teaching of chemistry and pharmacy was widely practiced in eighteenth-century medical faculties, exemplified at a very high standard in the lectures of Hermann Boerhaave at Leiden, Bergmann at Uppsala, and Black at Edinburgh. 

Hermann Boerhaave (1668-1735) was horn at Voorhout, near Leyden, and is called by Professor Thomas Thomson0 perhaps the most celebrated physician that ever existed, if we except Hippocrates. He received his degree of Doctor of Medicine at the University of Harderwyk in Holland in 1693. In 1702 he was appointed professor of medicine at Leyden, and later also was awarded professorships there in botany and in chemistry. The reputation of Boerhaave attracted a great body of students to Leyden and raised that university to an eminent position.for the study of medicine and the natural sciences.

Referring to acids and alkalis in order to understand chemical reactions was one thing, but thinking of acids and alkalis as basic to matter, or as principles of matter, was clearly another. Hermann Boerhaave accepted the former application and knew of Robert Boyle s technique of identifying acids, alkalis, and neutral substances by observing changes in color when a substance was dipped onto a little syrup of violets spread on white paper. However, in a work called A Short Recapitulation of Acid and Alkali that became part of his Elements of Chemistry, he noted how thinking of... 

Hoffmann and Stahl had been successful enough in their efforts to propose all-embracing medical theories, but their Dutch colleague, Hermann Boerhaave (1668-1738), who was active in Leyden, far surpassed them. He was the leading...

Stahl s phlogiston theory met with opposition at first, notably from a Dutch physician, Hermann Boerhaave (1668-1738), who argued that ordinary combustion and rusting could not be different versions of the same phenomenon. 

In his lectures from the first decades of the eighteenth century, Hermann Boerhaave defined chemistry as...
