finally, to the Animals, their parts and excretions original: uytdygfels; refers to substances produced or cast off by animals, such as horn, bone, or musk, used in early medicine.. To this I add not only their powers original: kragten; the medicinal virtues or healing efficacy of a substance., both external and internal, but—so as to mislead no one—also in what liquid they should be taken, and at what time.

Schroeder original: Scroderus; referring to Johann Schröder (1600–1664), a German physician whose pharmacopoeia was a standard medical text of the era. has given me the most guidance in this, because many others write either too briefly or are full of errors; meanwhile, I add my own observations to that which has been gathered from other authors. Besides Schroeder, there are Angelus Sala, Beguin, Charras, Le Febure, Crollius, Lemery, Lancilot, Rolfinck, the Acts of Leiden original: Acta Leidenfia; likely referring to medical records or academic publications from the University of Leiden., the Germanic Ephemerides original: Ephemerides Germanicæ; the first medical and scientific journal, published by the German Academy of Sciences., Basilius Valentinus, Mynsicht, Helmont, Glauber, and many more, all of whom are too numerous to mention. It seems to me that such authors have provided material enough to make a fine work from it: omitting what was redundant and correcting that which could be criticized in them.
