as I had occasion to try it) both with the Acid and the other Salts. For though it would lye very quiet with salt of Tartar, Spirit of Urine, or other bodies, whose Salts were either of an Alcalizate or fugitive Nature; yet did not the mingling of Oyle of Vitriol it self produce any hissing or Effervescence, which you know is wont to ensue upon the Affusion of that highly Acid Liquor upon either of the Bodies newly mentioned.
I think my self, sayes Eleutherius, beholden to you, for this Experiment; not only because I forsee you will make it helpful to you in the Enquiry you are now upon, but because it teaches us a Method, whereby we may prepare a numerous sort of new spirits, which though more simple then any that are thought Elementary, are manifestly endow’d with peculiar and powerfull qualities, some of which may probably be of considerable use in Physick, as well alone, as associated with other things; as one may hopefully guess by the redness of that Solution your sour Spirit made of Corals, and by some other circumstances of your Narrative. And suppose (pursues Eleutherius) that you are not so confin’d, for the separation of the Acid parts of these compound Spirits from the other, to employ Corals; but that you may as well make use of any Alcalizate Salt, or of Pearls, or Crabs eyes, or any other Body, upon which common Spirit of Vinager will easily work, and, to speak in an Helmontian Phrase, Exantlate it self.
