Here _Carneades_ was about to pass on to his Third Consideration, when _Eleutherius_ being desirous to hear what he could say to clear his second General Consideration from being repugnant to what he seem'd to think the true Theory of Mistion, prevented him by telling him, I somewhat wonder, _Carneades_, that You, who are in so many Points unsatisfied with the Peripatetick Opinion touching the Elements and Mixt Bodies, should also seem averse to that Notion touching the manner of Mistion, wherein the Chymists (though perhaps without knowing that they do so) agree with most of the Antient Philosophers that preceded _Aristotle_, and that for Reasons so considerable, that divers Modern Naturalists and Physitians, in other things unfavourable enough to the Spagyrists, do in this case side with them against the common Opinion of the Schools. If you should ask me (continues _Eleutherius_) what Reasons I mean? I should partly by the Writings of _Sennertus_ and other learned Men, and partly by my own Thoughts, be supply'd with more, then 'twere at present proper for me to Insist largely on. And therefore I shall mention only, and that briefly, three or four. Of these, I shall take the First from the state of the Controversie itself, and the genuine Notion of Mistion, which though much intricated by the Schoolmen, I take in short to be this, _Aristotle_, at least as many of his Interpreters expound him, and as indeed he Teaches in some places, where he professedly Dissents from the Antients, declares Mistion to be such a mutual Penetration, and perfect Union of the mingl'd Elements, that there is no Portion of the mixt Body, how Minute soever, which does not contain All, and Every of the Four Elements, or in which, if you please, all the Elements are not. And I remember, that he reprehends the Mistion taught by the Ancients, as too sleight or gross, for this Reason, that Bodies mixt according to their _Hypothesis_, though they appear so to humane Eyes, would not appear such to the acute Eyes of a _Lynx_, whose perfecter Sight would discerne the Elements, if they were no otherwise mingled, than as his Predecessors would have it, to be but Blended, not United; whereas the Antients, though they did not all Agree about what kind of Bodies were Mixt, yet they did almost unanimously hold, that in a compounded Bodie, though the _Miscibilia_, whether Elements, Principles, or whatever they pleas'd to call them, were associated in such small Parts, and with so much Exactness, that there was no sensible Part of the Mass but seem'd to be of the same Nature with the rest, and with the whole; Yet as to the Atomes, or other Insensible Parcels of Matter, whereof each of the _Miscibilia_ consisted, they retain'd each of them its own Nature, being but by Apposition or _Juxta_-Position united with the rest into one Bodie. So that although by virtue of this composition the mixt Body did perhaps obtain Divers new Qualities, yet still the Ingredients that Compounded
