The Fourth Part.

manifestly produc’d by the violent action of the Fire, but has never, for ought we know, been produc’d any other way. And indeed it seems but an inconsiderate Assertion of some Helmontians, that every sort of Body of a Peculiar Denomination must be produc’d by some Seminal power; as I think I could evince, if I thought it so necessary, as it is for me to hasten to what I have further to discourse. Nor need it much move us, that there are some who look upon whatsoever the Fire is employ’d to produce, not as upon Natural but Artificial Bodies. For there is not alwaies such a difference as many imagine betwixt the one and the other: Nor is it so easy as they think, clearly to assigne that which Properly, Constantly, and Sufficiently, Discriminates them. But not to engage my self in so nice a Disquisition, it may now suffice to observe, that a thing is commonly termed Artificial, when a parcel of matter is by the Artificers hand, or Tools, or both, brought to such a shape or Form, as he Design’d before-hand in his Mind: Whereas in many of the Chymical Productions the effect would be produc’d whether the Artificer intended it or no; and is oftentimes very much other then he Intended or Look’t for; and the Instruments employ’d, are not Tools Artificially fashion’d and shaped, like those of Tradesmen, for this or that particular Work; but, for the most part, Agents of Nature’s own providing, and whose chief Powers of Operation they receive from their own Nature or Texture, not the Artificer. And indeed, the Fire is as well a Natural Agent as Seed: And the Chymist that imployes it, does but apply Natural Agents and Patients, who being thus brought together, and acting according to their respective Natures, performe the worke themselves; as Apples, Plums, or other fruit, are natural Productions, though the Gardiner bring and fasten together the Sciens of the Stock, and both Water, and do perhaps divers other wayes Contribute to its bearing fruit. But, to proceed to what I was going to say, You may observe with me, Eleutherius, that, as I told You once before, Qualities sleight enough may serve to Denominate a Chymical Principle. For, when they anatomize a compound Body by the Fire, if they get a Substance inflamable,
