Dissolve Antimony or sulphur in the liquor of pebles or sand, coagulate the solution to a red mass; upon this mass pour spirit of urin, and let it extract in a gentle warmth. The spirit being coloured red, pour it off, and pour on other spirit, let it extract likewise, and this you must iterate so often, till the spirit will extract no more tincture; then pour all the extracts together and abstract the spirit of urin from it in Balneum through a limbeck, and there will remain a blood red liquor, and if you pour upon this spirit of wine it will extract a fairer tincture then the former was, leaving the fæces behind, and this tincture smelleth like garlick: and if it be digested three or four weeks in a gentle warmth, it will get a very pleasant smel, like unto the yellow prunes or plums: and if it remain longer yet in digestion, it will get a smel not inferior to musk and ambar; This tincture having been digested a long time, and got several smels, is not only notably by the fire increased in pleasantness of smel and taste, but also in vertue: for so many and various sweet smels are perceived in it, that it is to be admired, which variety and exaltation proceedeth only from the pure and ripening spirit of urin, for there is hid in it a fire, which doth not destroy but preserve and graduate all colours, whereof in another place more shall be said. N. B. Betwixt the spirit of urin and the animal and mineral Copper there appeareth a great sympathy; for it doth not only love copper above all other metals, and mingleth easily with it, and maketh it extraordinary fair, and of good use in Physick, but it prepareth it also to such a medicine, whereby all venerous sores (both by inward and outward use) how deep so ever they took root in the blood, without the use of any other medicaments, are perfectly cured; it maketh fruitful and barren, according as it is used; it cleanseth the matrix, hindreth the rising thereof, and miraculously furthereth womens courses that have been stayed, above all other medicaments of what name soever. If this spirit be mingled with the volatile (but not corrosive) spirit of vitriol or common salt there will come a salt out of it, which is inferior to none in fusibleness, and useful both in Alchymy and Physick. N. B. The liquor of the salt Of tartar, and the spirit of wine do not mix without water, this being the mean partaking of both of their natures, and if you add unto it spirit of urin it will not mingle but keep its own place: so that these three sorts of liquors, being put in the same glass, and though they be shaked never so much will not incorporate for all that: the liquor of the salt of tartar keepeth to the bottom, next to it will be the spirit of urin, and on the top of that is the spirit of wine: and if you pour a distilled oyl upon it, that will keep uppermost of all, so that you may keep four sorts of liquors in one glass, whereof none is mingled with the other.
