The Third Part.

I have not yet tryed, sayes Carneades, of what use the mention’d liquors may be in Physick, either as Medicines or as Menstruums: But I could mention now (and may another time) divers of the tryals that I made to satisfy my self of the difference of these two Liquors. But that, as I allow your thinking what you newly told me about Corals, I presume you will allow me, from what I have said already, to deduce this Corollary; That there are divers compound bodies, which may be resolv’d into four such differing Substances, as may as well merit the name of Principles, as those to which the Chymists freely give it. For since they scruple not to reckon that which I call the compound Spirit of Box, for the spirit, or as others would have it, the Mercury of that Wood, I see not, why the Acid liquor, and the other, should not each of them, especially that last named, be lookt upon as more worthy to be called an Elementary Principle; since it must needs be of a more simple nature then the Liquor, which was found to be divisible into that, and the Acid Spirit. And this further use (continues Carneades) may be made of our experiment to my present purpose, that it may give us a rise to suspect, that since a Liquor reputed by the Chymists to be, without dispute, Homogeneous, is by so slight a way divisible into two distinct and more simple Ingredients, some more skilful or happier Experimenter then I may find a way either further to divide one of these Spirits, or to resolve some or other, if not all, of those other Ingredients of mixt Bodies, that have hitherto pass’d among Chymists for their Elements or Principles.
