But though (sayes _Eleutherius_) You have alledg'd very plausible Arguments against the _tria Prima_, yet I see not how it will be possible for you to avoid acknowledging that Earth and Water are Elementary Ingredients, though not of Mineral Concretes, yet of all Animal and Vegetable Bodies; Since if any of these of what sort soever be committed to Distillation, there is regularly and constantly separated from it a phlegme or aqueous part and a _Caput Mortuum_ or Earth. I readily acknowledged (answers _Carneades_) it is not so easy to reject Water and Earth (and especially the former) as 'tis to reject the _Tria Prima_, from being the Elements of mixt Bodies; but 'tis not every difficult thing that is impossible. I consider then, as to Water, that the chief Qualities which make men give that name to any visible Substance, are, that it is Fluid or Liquid, and that it is insipid and inodorous. Now as for the tast of these qualities, I think you have never seen any of those separated substances that the Chymists call Phlegme which was perfectly devoyd both of Tast and Smell: and if you object, that yet it may be reasonably suppos'd, that since the whole Body is Liquid, the mass is nothing but Elementary Water faintly imbu'd with some of the Saline or Sulphureous parts of the same Concrete, which it retain'd with it upon its Separation from the Other Ingredients. To this I answer, That this Objection would not appear so stong [Transcriber's Note: strong] as it is plausible, if Chymists understood the Nature of Fluidity and Compactnesse; and that, as I formerly observ'd, to a Bodies being Fluid there is nothing necessary, but that it be divided into parts small enough; and that these parts be put into such a motion among themselves as to glide some this way and some that way, along each others Surfaces. So that, although a Concrete were never so dry, and had not any Water or other Liquor in-existent in it, yet such a Comminution of its parts may be made, by the fire or other Agents, as to turn a great portion of them into Liquor. Of this Truth I will give an instance, employ'd by our friend here present as one of the most conducive of his experiments to Illustrate the nature of Salts. If you Take, then, sea salt and melt it in the Fire to free it from the aqueous parts, and afterward distill it with a vehement Fire from burnt Clay, or any other, as dry a _Caput mortuum_ as you please, you will, as Chymists confess, [Errata: confesse (delete comma)] by teaching it drive over a good part of the Salt in the form of a Liquor. And to satisfy some ingenious men, That a great part of this Liquor was still true sea salt brought by the Operation of the Fire into Corpuscles so small, and perhaps so advantageously shap'd, as to be capable of the forme of a Fluid Body, He did in my presence poure to such spiritual salts a due proportion of the spirit (or salt and Phlegme) of Urine, whereby having evaporated the superfluous moisture,
