You may then in the next place (sayes _Carneades_) observe with me, that not only there are some Bodies, as Gold, and Silver, which do not by the usual Examens, made by Fire, Discover themselves to be mixt; but if (as You may Remember I formerly told You) it be a De-compound Body that is Dissipable into several Substances, by being expos'd to the Fire it may be resolv'd into such as are neither Elementary, nor such as it was upon its last mixture Compounded of; but into new Kinds of mixts. Of this I have already given You some Examples in Sope, Sugar of Lead, and Vitrioll. Now if we shall Consider that there are some Bodies, as well Natural, (as that I last nam'd) as Factitious, manifestly De-compounded; That in the Bowells of the Earth Nature may, as we see she sometimes does, make strange Mixtures; That Animals are nourish'd with other Animals and Plants; And, that these themselves have almost all of them their Nutriment and Growth, _either_ from a certain Nitrous Juice Harbour'd in the Pores of the Earth, _or_ from the Excrements of Animalls, _or_ from the putrify'd Bodies, either of living Creatures or Vegetables, _or_ from other Substances of a Compounded Nature; If, I say, we consider this, it may seem probable, that there may be among the Works of Nature (not to mention those of Art) a greater Number of De-compound Bodies, then men take Notice of; And indeed, as I have formerly also observ'd, it does not at all appear, that all Mixtures must be of Elementary Bodies; but it seems farr more probable, that there are divers sorts of compound Bodies, even in regard of all or some of their Ingredients, consider'd Antecedently to their Mixture. For though some seem to be made up by the immediate Coalitions of the Elements, or Principles themselves, and therefore may be call'd _Prima Mista_, or _Mista Primaria_; yet it seems that many other Bodies are mingl'd (if I may so speak) at the second hand, their immediate Ingredients being not Elementary, but these primary Mixts newly spoken of; And from divers of these Secondary sort of Mixts may result, by a further Composition, a Third sort, and so onwards. Nor is it improbable, that some Bodies are made up of Mixt Bodies, not all of the same Order, but of several; as (for Instance) a Concrete may consist of Ingredients, whereof the one may have been a primary, the other a Secondary Mixt Body; (as I have in Native Cinnaber, by my way of Resolving it, found both that Courser the [Errata: delete "the"] part that seems more properly to be Oar, and a Combustible Sulphur, and a Running Mercury:) or perhaps without any Ingredient of this latter sort, it may be compos'd of Mixt Bodies, some of them of the first, and some of the third Kind; And this may perhaps be somewhat Illustrated by reflecting upon what happens in some Chymical Preparations of those Medicines which they call their _Bezoardicum's_. For first, they take Antimony and Iron, which may be
