A compendious alchemical and natural-philosophical collection presenting theoretical and practical writings on the nature and generation of substances, especially metals and the so-called philosophical stone. It includes treatises on nature's operations (seed, first matter, putrefaction, and the generation of minerals and stones), practical praxis for producing tinctures and the stone, an extended treatise on sulphur and the classical elements and principles, Paracelsian books on generation, growth, preservation, life, death, transmutation, separation, and signatures, and a chemical dictionary translating obscure terms. The translator frames the material as an aid to understanding divine and natural processes while cautioning that experimental practice reflects early modern medical and chemical thought.
