But to come to particulars, and to write particularly of the death, and destruction of every naturall thing, and what the death of every thing is, and after what manner every thing is destroyed; you must know therefore in the first place, that the death of man is without doubt nothing else, but an end of his daily work, the taking away of the Aire, the decaying of the Naturall balsome, the extinguishing of the naturall light, and the great separation of the three substances, _viz._ the body, soule, and spirit, and their return from whence they came. For because a naturall man is of the earth, the Earth also is his Mother, into which hee must return, and there must lose his natural earthly flesh, and so be regenerated at the last day in a new celestiall, and purified flesh, as Christ said to _Nicodemus_ when hee came to him by night. For thus must these words bee understood of regeneration. [Sidenote: What the destruction of Metalls is.] The death, and destruction of Metalls is the disjoining of their bodies, and sulphureous fatnesse, which may bee done severall ways, as by calcination, reverberation, dissolution, cementation, and sublimation. [Sidenote: Calcination of Metalls is manifold.] But the calcination of Metalls is not of one sort: for one is made with Salt, another with Sulphur, another with _Aqua fortis_, and another with common Sublimate, and another with Quicksilver. [Sidenote: What Calcination with Salt is.] Calcination with Salt is that the Metall be made into very thin plates, and strowed with Salt, and cemented. [Sidenote: Calcination with Sulphur.] Calcination with Sulphur is, that the Metall bee made into thin plates, and strowed with Sulphur, and reverberated. [Sidenote: Calcination with Aqua fortis.] Calcination with _Aqua fortis_, is that the Metall bee made very small, and dissolved in _Aqua fortis_, and precipitated in it. [Sidenote: Calcination with Sublimate.] Calcination with sublimed Mercury is this, that the Metall bee made into thin plates, and that the Mercury bee put into an earthen vessell narrow towards the top, and wide at the bottome; and then let it be set into a gentle fire made with coales, which must bee blowed a little untill the Mercury begin to fume, and a white cloud goe forth of the mouth of the vessel, then let the Plate of the Metall bee put into the top of the vessel, and so the sublimed Mercury wil penetrate the Metall, and make it as brittle as a stone of coal. [Sidenote: Calcination with Quicksilver.] Calcination with Quicksilver, is that the Metall bee made very small, and thin, and be amalgamated with Quicksilver, and afterward the Quicksilver bee strained through Leather, and the Metall remain in the Leather like chalke, or sand.
