The Sixth Part.

I sufficiently intimated to you at that time (replies Carneades) that I propos’d this Example, chiefly to shew you how Nature may be Conceived to have made Elements, not to prove that she actually has made any; And you know, that a posse ad esse the Inference will not hold. But (continues Carneades) to answer more directly to the Objection drawn from Gold, I must tell You, that though I know very well that divers of the more sober Chymists have complain’d of the Vulgar Chymists, as of Mountebanks or Cheats, for pretending so vainly, as hitherto they have done, to Destroy Gold; Yet I know a certain Menstruum (which our Friend has made, and intends shortly to communicate to the Ingenious) of so piercing and powerfull a Quality, That if notwithstanding much care, and some skill, I did not much deceive myself, I have with it really destroy’d even refin’d Gold, and brought it into a Metalline Body of another colour and Nature, as I found by Tryals purposely made. And if some just Considerations did not for the present Forbid it, I could Perchance here shew you by another Experiment or Two of my own Trying, that such Menstruums may be made as to entice away and retain divers parts, from Bodies, which even the more Judicious and Experienc’d Spagyrists have pronounc’d irresoluble by the Fire. Though (which I Desire you would mark) in neither of these Instances, the Gold or Precious Stones be Analys’d into any of the Tria Prima, but only Reduc’d to new Concretes. And indeed there is a great Disparity betwixt the Operations of the several Agents whereby the Parts of a Body come to be Dissipated. As if (for Instance) you dissolve the purer sort of Vitriol in common Water, the Liquor will swallow up the Mineral, and so Dissociate its Corpuscles, that they will seem to make up but one Liquor with those of the water; and yet each of these Corpuscles retains
