The Sceptical Chymist - Robert Boyle - Bog

Doubts and Paradoxes, Touching the Spagyrist's Principles Commonly called Hypostatical; As they are wont to be Proposed and Defended by the Generality of Alchymists. Whereunto is promised Part of another Discourse relating to the same Subject. This interesting book purposely played the role of devil's advocate in the alchemical debate. Seemingly antagonistic to alchemy, it provoked the intended opposite effect: it helped to defend alchemy's worth as a sacred science. Extremely scarce.
