This spirit doth perform many things in medicine, & alchymy, as also in other arts, as you may easily conjecture; but here is not opportunity to speak more of these things, yet for the sake of the sick I shall add one thing, to which few things are to be compared; the plain & short process whereof I would not have thee be offended at. And it is this, _viz._ mix this spirit with the best rectifyed spirit of wine, digest this mixture some while, and the spirit of salt will separate the spirit of wine, and will make the oyl of wine swim on the top, the volatile salt being mortified: and this oyl is a most incomparable cordial, especially if with the said spirit of wine, spices have first been extracted, and with the said spirit of salt, gold hath been dissolved. For then in the digestion of this mixture, the oyl of wine being separated, attracts the essence of the cordial species, and of other vegetables, being extracted before with the spirit of wine, as also the tincture of gold, and so by consequence a most efficacious incomparable and universal medicine for all diseases, fortifying the _Humidum radicale_, that it may be able to overcome its enemies; for which let praise and glory be given to the immortal God for ever who hath revealed to us so great secrets. _Of the Extrinsecal use of the spirit of Salt in the Kitchen._ I said before that instead of Vinegar, and verjuice it may be used, as also instead of the juice of Limons, now it remains that I shew you how it is to be used, and that indeed as well for the sake of the healthy as the sick. Let him therefore that will dress a pullet, pigeons, veal, _&c._ in the first place put a sufficient quantity of spices, of water, and butter, and then as he pleaseth a greater, or lesser quantity of spirit of salt: and by this means fleshes are sooner made ready being boyled, then that common way; an old hen though the flesh thereof be old is made as tender as a chicken by the addition of this spirit: but he that will use it instead of the juice of Limons with rost meat, must put into it the pill of Limons for preservation sake, because it preserves it. It is used instead of verjuice by it self alone, or mixed with a little sugar, if it be too acid. He that will stew beef, and make it as tender as kid, must first dissolve in it tartar and a little salt before he wets the flesh therewith, and the flesh will not only be preserved but made tender thereby: but to keep flesh a long time you must mix some water therewith, and with weights press down the flesh, that it may be covered with the pickle: for by this means flesh may be preserved a great while. After the same manner may all kinds of garden fruits be preserved, as cucumbers, purslain, fennel, broom, German capers, _&c._ and indeed better than in vinegar. Also flowers, and hearbs may a long while be preserved by the help thereof, so that you may have a rose all the winter.
