Woodcut showing Annibal Barlet lecturing in his laboratory; students on his chemical course take notes in the foreground. On the table is a small reverberatory furnace. Illustration from Barlet's 'Le Vray et Methodique Cours de la Physique Resolutive Vulgairement dite Chymie' ('The True and Methodical Course in Resolutive Physick, Commonly called Chemistry'), published in Paris in 1657. Although the book contains a great deal of alchemical jargon, it is for the most part good practical pharmaceutical chemistry. Barlet gave regular chemical courses in Paris, attended by the diarist John Evelyn amongst others.
