Cornelius Drebbel - inventor and alchemist - Paul Ferguson - 12-04-2024
Dissertation by Gerrit Tierie.
"In De Quinta Essentia Drebbel discusses in alchemistic terms, how the essence extracted from metals, minerals, plants and animals may be prepared and then used as medicine. From the directions he gives together with philosophical reflections on the subject, we gather, that by essence of metals he meant salts, such as for instance acetates, and by the essence of plants, alcoholic extracts and by the essence of animals, a kind of watery meat extract or bouillon."
