Acid, and the other not so manifestly Acid as the Tartar it self; The same Vinous Juice after some time, especially if it be not carefully kept, Degenerates into that very sour Liquor called Vinegar; from which you may obtain by the Fire a Spirit and a Crystalline Salt differing enough from the Spirit and Lixiviate Salt of Tartar. And if you pour the Dephlegm'd Spirit of the Vinegar upon the Salt of Tartar, there will be produc'd such a Conflict or Ebullition as if there were scarce two more contrary Bodies in Nature; and oftentimes in this Vinager you may observe part of the matter to be turned into an innumerable company of swimming Animals, which our Friend having divers years ago observed, hath in one of his Papers taught us how to discover clearly without the help of a _Microscope_. Into all these various Schemes of matter, or differingly Qualifyed Bodies, besides divers others that I purposely forbear to mention, may the Water that is imbib'd by the roots of the Vine be brought, partly by the formative power of the plant, and partly by supervenient Agents or Causes, without the visible concurrence of any extraneous Ingredient; but if we be allowed to add to the Productions of this transmuted Water a few other substances, we may much encrease the Variety of such Bodies; although in this second sort of Productions, the Vinous parts seem scarce to retain any thing of the much more fix'd Bodies wherewith they were mingl'd; but only to have by their Mixture with them acquir'd such a Disposition, that in their recess occasion'd by the Fire they came to be alter'd as to shape, or Bigness, or both, and associated after a New manner. Thus, as I formerly told you, I did by the Addition of a _Caput Mortuum_ of Antimony, and some other Bodies unfit for Distillation, obtain from crude Tartar, store of a very Volatile and Crystalline Salt, differing very much in smell and other Qualities from the usuall salts of Tartar.
