Chap. I Of the Definitions of Alchimy
In many ancient Bookes there are found many definitions of this Art, the intentions wherof we must consider in this Chapter. For Hermes saith of this Science: Alchimy is a Corporal Science simply composed of one and by one, naturally conioyning things more precious, knowledge and effect, and conuerting them by a naturall commixtion into a better kind. A certain other saith: Alchimy is a Science, teaching how to transforme any kind of mettall into another: and that by a proper medicine, as it appeareth by many Philosophers Bookes. Alchimy therfore is a science teaching how to make and compound a certaine medicine, which is called Elixir, the which when it is cast vpon mettals or imperfect bodies, doth fully perfect them in the verie proiection.
