The death of all naturall things is nothing else but an alteration and destruction of their powers, and vertues, a predominancy of that which is evill, and an overcoming of what is good, an abolishing of the former nature, and generation of a new, and another nature. For you must know that there are many things that, whilst they are alive, have in them severall vertues, but when they are dead retaine little or nothing of their vertue, but become unsavory, and unprofitable. So on the contrary many things, whilest they live, are bad, but after they are dead, and corrupted, manifest a manifold power, and vertue, and are very usefull. Wee could bring many examples to confirme this, but that doth not belong to our purpose. But that I may not seem to write according to mine own opinion only, but out of my experience, it will bee necessary that I produce one example, with which I shall silence those Sophisters, who say, that wee can receive nothing from dead things, neither must we seek, or expect to find any thing in them. The reason is, because they do esteem nothing of the preparations of Alchymists, by which many such like great secrets are found out. For looke upon Mercury, crude Sulphur, and crude Antimony, as they are taken out of their Mines, _i.e._ whilest they are living, and see what little vertue there is in them, how slowly they put forth their vertues, yea they do more hurt, then good, and are rather poison, then a Medicine. But if through the industry of a skilfull Alchymist, they bee corrupted in their first substance, and wisely prepared (_viz._ if Mercury be coagulated, precipitated, sublimed, dissolved, and turned into an oyle, if Sulphur bee sublimed, calcined, reverberated, and turned into an oyle; also if Antimony bee sublimed, calcined, and reverberated and turned into oyle) you shall see how usefull they are, how much strength, and vertue they have, and how quickly they put forth, and shew their efficacy, which no man is able to speak enough in the commendation of, or to describe. For many are their vertues, yea more then will ever bee found out by any man. Wherefore let every faithfull Alchymist, and Physitian spend their whole lives in searching into these three: For they will abundantly recompense him for all his labour, study, and costs.
