I know there may be a Distinction betwixt Matter Immanent, when the material Parts remain and retain their own Nature in the things materiated, as some of the Schoolmen speak, (in which sence Wood, Stones and Lime are the matter of a House,) and Transient, which in the materiated thing is so alter’d, as to receive a new Forme, without being capable of re-admitting again the Old. In which sence the Friends of this Distinction say, that Chyle is the matter of Blood, and Blood that of a Humane Body, of all whose Parts ’tis presum’d to be the Aliment. I know also that it may be said, that of material Principles, some are common to all mixt Bodies, as Aristotles four Elements, or the Chymists Tria Prima; others Peculiar, which belong to this or that sort of Bodies; as Butter and a kind of whey may be said to be the Proper Principles of Cream: and I deny not, but that these Distinctions may in some Cases be of Use; but partly by what I have said already, and partly by what I am to say, You may easily enough guess in what sence I admit them, and discerne that in such a sence they will either illustrate some of my Opinions, or at least will not overthrow any of them.
To prosecute then what I was saying before, I will add to this purpose, That since the Major part of Chymists Credit, what those they call Philosophers affirme of their Stone, I may represent to them, that though when Common Gold and Lead are mingled Together, the Lead may be sever’d almost un-alter’d from the Gold; yet if instead of Gold a Tantillum of the Red Elixir be mingled with the Saturn, their Union will be so indissoluble in the perfect Gold that will be produc’d by it, that there is no known, nor perhaps no possible way of separating the diffus’d Elixir from the fixed Lead, but they both Constitute a most permanent Body, wherein the Saturne seems to have quite lost its Properties that made it be call’d Lead, and to have been rather transmuted by the Elixir, then barely associated to it. So that it seems not alwayes necessary, that the Bodies that are put together per minima, should each retain its own Nature; So as when the Mass it Self is dissipated by the Fire, to be more dispos’d to re-appear in its Pristine Forme, then in any new one, which by a stricter association of its Parts with those of some of the other Ingredients of the Compositum, then with one another, it may have acquired.
And if it be objected, that unless the Hypothesis I oppose be admitted, in such Cases as I have proposed there would not be an Union but a Destruction of mingled Bodies, which seems all one as to say, that of such Bodies there is no mistion at all; I answer, that though the Substances that are mingl’d remain, only their Accidents are Destroy’d, and though we may with tollerable Congruity call them Miscibilia, because they are Distinct Bodies before they are put together, however afterwards they are so Confounded that I should rather call them Concretions, or Resulting Bodies, than mixt ones; and though, perhaps, some other and better Account may be propos’d, upon which the name of mistion may remain; yet if what I have said be thought Reason, I shall not wrangle about Words, though I think it fitter to alter a Terme of Art, then reject a new Truth, because it suits not with it. If it be also Objected that this Notion of mine, concerning mixtion, though it may be allow’d, when Bodies already Compounded are put to be mingl’d, yet it is not applicable to those mixtions that are immediately made of the Elements, or Principles themselves; I Answer in the first place, that I here Consider the Nature of mixtion somewhat more Generally, then the Chymists, who yet cannot deny that there are oftentimes Mixtures, and those very durable ones, made of Bodies that are not Elementary. And in the next place, that though it may be probably pretended that in those Mixtures that are made immediately of the Bodies that are call’d Principles or Elements, the mingl’d Ingredients may better retain their own Nature in the Compounded Mass, and be more easily separated from thence; yet, besides that it may be doubted, whether there be any such Primary Bodies, I see not why the reason I alleadg’d, of the destructibility of the Ingredients of Bodies in General, may not sometimes be Applicable to Salt Sulphur or Mercury; ’till it be shewn upon what account we are to believe them Priviledged. And however, (if you please but to recall to mind, to what purpose I told you at First, I meant to speak of Mistion at this Time) you will perhaps allow that what I have hitherto Discoursed about it may not only give some Light to the Nature of it in general (especially when I shall have an Opportunity to Declare to you my thoughts on that subject more fully) but may on some Occasions also be Serviceable to me in the Insuing Part of this Discourse.
But, to look back Now to that part of our Discourse, whence this Excursion concerning Mistion has so long diverted us, though we there Deduc’d, from the differing Substances obtained from a Plant nourished only with Water, and from some other things, that it was not necessary that nature should alwaies compound a Body at first of all such differing bodies as the fire could afterwards make it afford; yet this is not all that may be collected from those Experiments. For from them there seems also Deducible something that Subverts an other Foundation of the Chymical Doctrine. For since that (as we have seen) out of fair Water alone, not only Spirit, but Oyle, and Salt, and Earth may be Produced; It will follow that Salt and Sulphur are not Primogeneal Bodies, and principles, since they are every Day made out of plain Water by the Texture which the Seed or Seminal principle of plants puts it into. And this would not perhaps seem so strange, if through pride, or negligence, We were not Wont to Overlook the Obvious and Familiar Workings of Nature; For if We consider what slight Qualities they are that serve to denominate one of the Tria Prima, We shall find that Nature do’s frequently enough work as great Alterations in divers parcells of matter: For to be readily dissoluble in water, is enough to make the body that is so, passe for a Salt. And yet I see not why from a new shufling and Disposition of the Component Particles of a body, it should be much harder for Nature to compose a body dissoluble in Water, of a portion of Water that was not so before, then of the Liquid substance of an Egg, which will easily mix with Water, to produce by the bare warmth of a hatching Hen, Membrans, Feathers, Tendons, and other parts, that are not dissoluble in Water as that Liquid Substance was: Nor is the Hardness and Brittleness of Salt more difficult for Nature to introduce into such a yielding body as Water, then it is for her to make the Bones of a Chick out of the tender Substance of the Liquors of an Egg. But instead of prosecuting this consideration, as I easily might, I will proceed, as soon as I have taken notice of an objection that lies in my Way. For I easily foresee it will be alledged, that the above mentioned Examples are all taken from Plants, and Animals, in whom the Matter is Fashioned by the Plastick power of the seed, or something analogous thereunto. Whereas the Fire do’s not act like any of the Seminal Principles, but destroyes them all, when they come within its Reach. But to this I shall need at present to make but this easy Answer, That whether it be a Seminal Principle, or any other which fashions that Matter after those various manners I have mentioned to You, yet ’tis Evident, that either by the Plastick principle Alone, or that and Heat Together, or by some Other cause capable to contex the matter, it is yet possible that the matter may be Anew contriv’d into such Bodies. And ’tis only for the Possibility of this that I am now contending.
