Conspicuous Mass of Liquor; and as for the Salts, some of the more Volatile of them Subliming to the upper part of the Glass, the others Corrode the Copper, and uniting themselves with it do strangely alter and Disguise its Metallick Form, and compose with it a new kind of Concrete inflamable like Sulphur; concerning which I shall not now say any thing, since I can Referr You to the Diligent Observations which I remember Mr. _Boyle_ has made concerning this Odde kind of Verdigrease. But Continues _Carneades_ smiling, you know I was not cut out for a Mountebank, and therefore I will hasten to resume the person of a Sceptick, and take up my discourse where You diverted me from prosecuting it. In the next place, then, I consider, that, as there are some Bodies which yield not so many as the three Principles; so there are many others, that in their Resolution Exhibite more principles than three; and that therefore the Ternary Number is not that of the Universal and Adequate Principles of Bodies. If you allow of the Discourse I ately [Errata: lately] made You, touching the primary Associations of the small Particles of matter, You will scarce think it improbable, that of such Elementary Corpuscles there may be more sorts then either three, or four, or five. And if you will grant, what will scarce be deny'd, that Corpuscles of a compounded Nature may in all the wonted Examples of Chymists pass for Elementary, I see not, why you should think it impossible, that as _Aqua Fortis_, or _Aqua Regis_ will make a Separation of colliquated Silver and Gold, though the Fire cannot; so there may be some Agent found out so subtile and so powerfull, at least in respect of those particular compounded Corpuscles, as to be able to resolve them into those more simple ones, whereof they consist, and consequently encrease the number of the Distinct Substances, whereinto the mixt Body has been hitherto thought resoluble. And if that be true, which I recited to you a while ago out of _Helmont_ concerning the Operations of the _Alkahest_, which divides Bodies into other Distinct Substances, both as to number and Nature, then the Fire does; it will not a little countenance my Conjecture. But confining our selves to such wayes of Analyzing mix'd Bodies, as are already not unknown to Chymists, it may without Absurdity be Question'd, whether besides those grosser Elements of Bodies, which they call Salt Sulphur and Mercury, there may not be Ingredients of a more Subtile Nature, which being extreamly little, and not being in themselves Visible, may escape unheeded at the Junctures of the Destillatory Vessels, though never so carefully Luted. For let me observe to you one thing, which though not taken notice of by Chymists, may be a notion of good Use in divers Cases to a Naturalist, that we may well suspect, that there may be severall Sorts of Bodies, which are not Immediate Objects of any one of our senses; since we See, that not only those little Corpuscles that issue
