Take sweet Must or juice of grapes, as soon as it is squeezed out, boyl it to the consistency of honey- and then mix it with sand, corals, or (which is better) with flores of Antimony, and so distill it, and it will yield such another spirit as that which is made of honey or sugar, only that this is somewhat tarter than that of honey. With honey, sugar and the juice of grapes, several metals may be dissolved in boyling and so prepared and made up into divers medicaments, both with and without distillation, after the same manner as was taught above with tartar: for honey, sugar, and the juice of grapes, are nothing else but a sweet salt, which by fermentation and addition of some sower thing, may be changed into a sower Tartar, in all like unto that which is gathered in the wine vessels. There may be made also a tartar out of cherries, pears, apples, figs, and all other fruit, yielding a sweet juice; as also of rye, wheat, oats, barley and the like, whereof in the third part more shall be said. For every sweet liquor of vegetables, if it be turned inside out, by fermentation may be changed to a natural sowre tartar; and it is utterly false, that (as some do suppose) only wine yields tartar, which by daily use made of it by those that have very hungry stomachs (like Woolves) indistinctly together with the nourishment went into the limbs, and there turned to a stony matter. If this were true, than in cold Countries, where no wine groweth, men would not be troubled with the Gout or Stone; the Contrary whereof is seen daily: though I must confess, that among all vegetables none yeildeth more than the vine, the concurrent acidity being the cause thereof; for it turneth the sweetness into tartar; for the sowrer the wine is, the more tartar it yieldeth; and so much the sweeter, so much the less tartar. By this discourse an industrious Chymist may easily come to know the original nature and properties of tartar, and in default of wine, how to make it out of other vegetables; common salt or the salt of tartar may be distilled with honey, sugar, or sodden wine (_sapa_) and it will yield such strong spirits, that metals may be dissolved with them, and they are not to be despised in Physick and Alchymy. _Of oyl Olive._
