you have put it into a Cucurbit with a blind Still, let it rot in dung for a moneth; then distil it in Sand. The liquor distilled from it being rectified in a deep Cucurbit, affords a spirit and a volatile Salt.

This operation may be performed more compendiously, if you evaporate fresh Urin to a fourth part of what you first took, to wit, that when the phlegm is exhaled, the saline particles may mor•…•… closely incorporate with the sulphureous and earthy ones. To this thick composition (after you have put it into the Cucurbit) pour either a Lie made of Ashes or Salt of Tartar, or the dissolution of slacked Lime; and then putting on the Still, distil it in an Oven of Sand; and you will easily gain a Spirit, and a vo∣latile Salt, which by rectification are purified and separated.

The reason of these proceedings is, because in that the Urin consists of a double * 1.1 kind ef Salt, that is to say, a nitrous and a volatile, together with a great deal of Sul∣phur and Earth, the particles of volatile Salt (whilest the mixture remains entire) are so detained and strictly compacted by the other saline ones, together with the rest of the thicker elements, that the spirits cannot break forth, or be divided and separated by the force of fire; but when by long rotting [in the dung] the mixtion of the li∣quor is loosened, the saline volatile particles, which at length do extricate or disen∣tangle themselves from the rest, ascend first in the distillation. Moreover the same effect also doth easily ensue, when a fixed Salt that is different from the nitrous, is poured in; for whilest the particles of the nitrous Salt are laid hold on by those of the other Salt that is infused, the volatile Salt escaping out of its restraint, doth easily make its way and is gone. Hither you may refer what I shall hereafter say of the di∣stillation of Sal Armoniack.
