[Guillaume-François ROUELLE (1703-1770)]. Augustin ROUX (1726-1776). Manuscrit, Cours de Chimie ou Leçons de Mr Rouelle Recueillies par Mr Roux pendant les années 1754 1755 et Rédigées en 1756, Revues augmentées et corrigées par le même en 1757 et 1758; 688pages d'un fort volume in-4 (23,5x19cm), cartonnage de papier marbré de l'époque, tranches rouges. Important manuscript of Rouelle's chemistry course collected by the Bordeaux physician Roux. The manuscript is carefully drawn up, very legible, ruled in pencil, with wide margins for headings and notes. A detailed table appears on the last 14 pages. The course is divided into three parts, preceded by a preliminary discourse and an exposition of principles and instruments. Part One: The Plant Kingdom. I Analise or decomposition. II On sinchrese or recomposition. Fermentation. Varnishes. The art of dyeing. Second part: Animal kingdom. Milk analysis. Urine. Putrefaction. Third part: Mineral kingdom: bitumens, succin, vitriolic acid, sulfur, nitre, sea salt; semi-metals: mercury, arsenic, cobolt, antimony, zinc, bismuth; metals: lead, tin, iron, copper, silver, gold; Alchemy. Of modest origins, Augustin Roux studied in Bordeaux, where he was awarded a doctorate in 1750; thanks to Montesquieu's recommendation, he came to Paris, where he was agrégé at the Faculty of Medicine, where he was appointed professor of chemistry in 1771. A friend of d'Holbach, he wrote several works, including two articles for the Encyclopédie.
