applicable to this purpose I have elsewhere given you. To which I may add, that whereas in a mixture of Sulphur and Salt of Tartar well melted and incorporated together, the action of pure spirit of wine digested on it is to separate the sulphureous from the Alcalizate Parts, by dissolving the former and leaving the latter, the action of Wine (probably upon the score of its copious Phlegme) upon the same mixture is to divide it into Corpuscles consisting of both Alcalizate and Sulphureous Parts united. And if it be objected, that this is but a Factitious Concrete; I answer, that however the instance may serve to illustrate what I propos'd, if not to prove it; and that Nature her self doth in the bowels of the Earth make Decompounded Bodies, as we see in Vitriol, Cinnaber, and even in Sulphur it self; I will not urge that the Fire divides new Milk into five differing Substances; but Runnet and Acid Liquors divide it into a Coagulated matter and a thin Whey: And on the other side churning divides it into Butter and Butter-milk, which may either of them be yet reduc'd to other substances differing from the former. I will not presse this, I say, nor other instances of this Nature, because I cannot in few words answer what may be objected, that these Concretes sequestred without the help of the Fire may by it be further divided into Hypostatical Principles. But I will rather represent, That whereas the same spirit of Wine will dissociare [Transcriber's Note: dissociate] the Parts of Camphire, and make them one Liquor with it self; _Aqua Fortis_ will also disjoyn them, and put them into motion; but so as to keep them together, and yet alter their Texture into the form of an Oyle. I know also an uncompounded Liquor, that an extraordinary Chymist would not allow to be so much as Saline, which doth (as I have try'd) from Coral it self (as fixt as divers judicious writers assert that Concrete to be) not only obtain a noble Tincture, Without the Intervention of Nitre or other Salts; but will carry over the Tincture in Distillation. And if some reasons did not forbid me, I could now tell you of a _Menstruum_ I make my self, that doth more odly dissociate the parts of Minerals very fixt in the fire. So that it seems not incredible, that there may be some Agent or way of Operation found, whereby this or that Concrete, if not all Firme Bodies, may be resolv'd into parts so very minute and so unapt to stick close to one another, that none of them may be fixt enough to stay behind in a strong Fire, and to be incapable of Distillation; nor consequently to be look'd upon as Earth. But to return to _Helmont_, the same Authour somewhere supply's me with another Argument against the Earth's being such an Element as my Adversaries would have it. For he somewhere affirms, that he can reduce all the Terrestrial parts of mixt bodies into insipid water; whence we may argue against the Earths being one of their Elements, even from that Notion of Elements which you may
