it, retaining their own Nature, were by the Destruction of the _Compositum_ separable from each other, the minute Parts disingag'd from those of a differing Nature, and associated with those of their own sort returning to be again, Fire, Earth, or Water, as they were before they chanc'd to be Ingredients of that _Compositum_. This may be explain'd (Continues _Eleutherius_,) by a piece of Cloath made of white and black threds interwoven, wherein though the whole piece appear neither white nor black, but of a resulting Colour, that is gray, yet each of the white and black threds that compose it, remains what it was before, as would appear if the threds were pull'd asunder, and sorted each Colour by it self. This (pursues _Eleutherius_) being, as I understand it, the State of the Controversie, and the _Aristotelians_ after their Master Commonly Defining, that Mistion is _Miscibilium alteratorum Unio_, that seems to comport much better with the Opinion of the Chymists, then with that of their Adversaries, since according to that as the newly mention'd Example declares, there is but a _Juxta_-position of separable Corpuscles, retaining each its own Nature, whereas according to the _Aristotelians_, when what they are pleas'd to call a mixt Body results from the Concourse of the Elements, the _Miscibilia_ cannot so properly be said to be Alter'd, as Destroy'd, since there is no Part in the mixt Body, how small soever, that can be call'd either Fir [Transcriber's Note: Fire], or Air, or Water, or Earth.
