But there is yet another manner of proceeding, in the separation of the substances of common water: and more spirituall then the precedent. Take very clean water out of a well, river or fountain, let it settle twenty foure houres, and take the pure and the cleare, which you shall put in vessels of _Beauvois_ earth: well stopped to putrifie in hot dung fourty dayes, renewing it two or three times every week, filter the water, and give only five or six boylings, scumming off the scurfes that arise thereon with a feather, then put it in _Cornues_ of glasse, not putting therein but the third part, or the moity at most, of that which they may containe and distill of two parts three; then change the Recipient, and accomplish to distill all the water, but with an easie fire. Then strengthen the fire, by little and little, till you see small fumes ascend, continue this degree of fire, with increasing untill it mount no more. Let the fire quench of it selfe and recoole the vessell: then gather the salt which shall be so elevated towards the beck of the _Cornue_, and within the recipient, and keep it in a vessel of earth, very close and sealed in a warm and dry place that it melt not, nor dissolve. Put the _Cornue_ to againe with that which remains in the bottome, and strengthen the fire untill you see a reddish oile; end your distillation, after cease the fire. Take the black feces, that remain in the bottome, stampe them, and put them in a sublimatory of good earth, of an inch thick, and no more, for six houres, first a little fire, then reinforce it for twelve others, till the sublimatory be red, the fire being alwaies in the same degree: let it coole and gather the salt which will be mounted, and keep it as the former. This is the second _sal Armoniac volatill_, which is extracted from the water: and the one, and the other, have great power to the dissolution of gold, carrying no danger with then as your common _sal Armoniac_ may doe; which hath bad qualities in it, there, where this is extracted from a substance so familiar to mans body, which, is sweet water. Now take all the feces & residences, which remain in the bottome of the vessell, bruise them, and make them dissolve in the first water, which you shall have distilled, after you have warmed it a little, that it may dissolve the salt that may be there. Let them repose, then evacuate, and put them to distill with halfe the water: Then change the Recipient, and with a little stronger fire, distill the Surplufage of the water, and keep them each a part, in a cold place. But doe not perfect to congeal all the salt in the bottome of the vessell, but leave therein a little moisture, to create flakes of ice. If it be not white enough, let it calcine for three or foure houres in a pot of earth not leaded, after dissolve it in the second water, filter and congeale it, and keep it in a dry place, for this is salt fix and fusible. If in drawing the first _Salarmoniac_, _volatill_, the
