The Fourth Part.

are endow’d with very differing Qualities according to the Nature of the Particular Bodies that afforded them (though I fear seldom with so much of the specifick vertues as is wont to be imagin’d) is freely confess’d both by Physitians and Chymists. But, Eleutherius, (sayes Carneades) we may here take Notice that the Chymists do as well in this case, as in many others, allow themselves a License to abuse Words: For not again to argue from the differing properties of Tinctures, that they are not exactly pure and Elementary Sulphurs; they would easily appear not to be so much as Sulphur’s, although we should allow Chymical Oyles to deserve that Name. For however in some Mineral Tinctures the Natural fixtness of the extracted Body does not alwayes suffer it to be easily further resoluble into differing substances; Yet in very many extracts drawn from Vegetables, it may very easily be manifested that the spirit of Wine has not sequestred the sulphureous Ingredient from the saline and Mercurial ones; but has dissolv’d (for I take it to be a Solution) the finer Parts of the Concrete (without making any nice distinction of their being perfectly Sulphureous or not) and united it self with them into a kind of Magistery; which consequently must contain Ingredients or Parts of several sorts. For we see that the stones that are rich in vitriol, being often drench’d with rain-Water, the Liquor will then extract a fine and transparent substance coagulable into Vitriol; and yet though this Vitriol be readily dissoluble in Water, it is not a true Elementary Salt, but, as You know, a body resoluble into very differing Parts, whereof one (as I shall have occasion to tell You anon) is yet of a Metalline, and consequently not of an Elementary Nature. You may consider also, that common Sulphur is readily dissoluble in Oyle of Turpentine, though notwithstanding its Name it abounds as well, if not as much, in Salt as in true Sulphur; witness the great quantity of saline Liquor it affords being set to flame away under a glasse Bell. Nay I have, which perhaps You will think strange, with the same Oyle of Turpentine alone easily enough dissolv’d crude Antimony finely powder’d into a Blood-red Balsam, wherewith perhaps considerable things may be perform’d in Surgery. And if
