and yet he himself (but with his wonted modesty) Substitutes instead of the Description of Libavius, another, which many Readers, especially if they be not Peripateticks, will not know what to make of. For scarce telling us any more, then that in all bodies that which is found besides Salt and Sulphur, and the Elements, or, as they call them, Phlegm and Dead Earth, is that Spirit which in Aristotles Language may be call’d ουσιαν αναλογον τω των αϛρων ϛοιχαιω. He sayes that which I confess is not at all satisfactory to me, who do not love to seem to acquiesce in any mans Mystical Doctrines, that I may be thought to understand them.
If (sayes Eleutherius) I durst presume that the same thing would be thought clear by me, and those that are fond of such cloudy Expressions as You justly Tax the Chymists for, I should venture to offer to Consideration, whether or no, since the Mercurial Principle that arises from Distillation is unanimously asserted to be distinct from the salt and Sulphur of the same Concrete, that may not be call’d the Mercury of a Body, which though it ascend in Distillation, as do the Phlegme and Sulphur, is neither insipid like the former, nor inflamable like the latter. And therefore I would substitute to the too much abused Name of Mercury, the more clear and Familiar Appellation of Spirit, which is also now very much made use of even by the Chymists themselves, of our times, though they have not given us so Distinct an Explication, as were fit, of what may be call’d the Spirit of a mixt Body.
I should not perhaps (sayes Carneades) much quarrel with your Notion of Mercury. But as for the Chymists, what they can mean, with congruity to their own Principles, by the Mercury of Animals and Vegetables, ’twill not be so easie to find out; for they ascribe Tasts only to the Saline Principle, and consequently would be much put to it to shew what Liquor it is, in the Resolution of Bodies, that not being insipid, for that they call Phlegme, neither is inflamable as Oyle or Sulphur, nor has any Tast; which according to them must proceed from a Mixture, at least,
