CHAP. I.
Of the Definitions of Alchimy.
N 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.
