Such a fire is for the most part drawn forth out of man’s Urine being putrified by it self for the space of some weeks, and is by rectifying converted into a moist and fiery essence as the second part of my Furnaces sheweth; I have there taught a more easy manner of drawing forth the same fire out of Sal-Armoniack, which is prepared out of Urine, and by the addition of a strong Lixivium it is distilled and rectified.
I have also taught the manner of preparing the same fire out of Sal-armoniack by the Addition of Lapis Calaminaris, by distilling it through a Retort.
Spirits rightly prepared after these manners are equally profitable in Medicine, Alchymy, and other arts; because they are those which being well made are all of them good, after what manner soever they may be prepared.
But although these volatile animal fires do readily serve for the performing of famous and notable things (and the fixed Salt of Urine it self, may by Distillation and rectification be con-centrated into another kind of fire) yet they are at a far distance from that true Philosophical fire which the Ancients have hidden with so great care and diligence, because that in these preparations the best and chiefest part of the fire flies away and is lost. But this I say, that these fiery Spirits of Urine being con-centrated even as I have taught them to be, are indeed able to effect all those things which I have attributed to them, and shall as yet attribute. But indeed they do not coagulate the con-centrated fire of the Vine, which coagulation is not the least key for the composing of an universal Medicine.
For when the Spirit of Urine attains this nature, that by coagulating the most subtile Spirit of Wine, (when poured on it) into a Salt, this Salt extracts the soul of Gold duely prepared; the which also, if it be changed by it self, and converted into a dry and sweet Salt, and be fixed, possesseth the virtues of a Medicament of a most famous and great use in Medicine.
Every one that is illustrated, but even with the least light of nature, shall be able by an easy business, to smell out what may hiddenly lurk under this Salt.
From the most pure Vine is the substance of the Spirit of Wine, which strengthens the heart of man beyond all other things, as also his brain, and other members.
The Spirit of Urine is the purest and most subtile Mercurial Animal Salt, not having its like in penetrating, opening, and resolving.
This subtile Mercurial, Animal and piercing fire therefore, being joyned to the most pure vegetable, that is, the Spirit of Wine, that it may be changed together with it into a dry Medicine, any one shall be able by an easy conjecture to foresee what it will effect in Medicine.
But that I may make manifest the errour, and demonstrate the cause wherefore a Spirit of Urine is so seldom prepared, which will coagulate the Spirit of Wine into a Salt, I admonish that a respect be had by every one of the following particulars.
