Petri Poterii - Opera Omnia Practica et Chymica - 1741

In octavo (cm 17 x 23), pp. 620. Contemporary limp parchment binding completely detached from the book, which nevertheless remains intact and without omissions. White and fresh pages. First Italian edition of this work by Pierre Potier, French Paracelsian physician, expelled in 1609 from the Faculty of Medicine in Paris for having used antimony, who lived for a long time in Italy in the early seventeenth century, with critical annotations by F. Hoffmann. The work is characterized by the large portion devoted to chemical preparations of pharmacological remedies in the section Pharmacopea Spayricae (from page 283 to page 495). On pages 433-436 there is the notable section in which Potier discusses the stone found in Bologna, the solar phosphorus or baryta, with an explanation of the method to obtain it.
