Liquor was call'd Spirit of Vinager; nor can any such Acid Parts as were put to the _Minium_ be Separated by any known way from the _Saccharum Saturni_ resulting from them both; for not only there is no Sowrness at all, but an admirable Sweetness to be tasted in the Concretion; and not only I found not that Spirit of Wine, which otherwise will immediately hiss when mingl'd with strong Spirit of Vinager, would hiss being pour'd upon _Saccharum Saturni_, wherein yet the Acid Salt of Vinager, did it Survive, may seem to be concentrated; but upon the Distillation of _Saccharum Saturni_ by its Self I found indeed a Liquor very Penetrant, but not at all Acid, and differing as well in smell and other Qualities, as in tast, from the Spirit of Vinager; which likewise seem'd to have left some of its Parts very firmly united to the _Caput Mortuum_, which though of a Leaden Nature was in smell, Colour, &c. differing from _Minium_; which brings into my mind, that though two Powders, the one Blew, and the other Yellow, may appear a Green mixture, without either of them losing its own Colour, as a good Microscope has sometimes inform'd me; yet having mingl'd _Minium_ and _Sal Armoniack_ in a requisite Proportion, and expos'd them in a Glass Vessel to the Fire, the whole Mass became White, and the Red Corpuscles were destroy'd; for though the Calcin'd Lead was separable from the Salt, yet you'l easily beleeve it did not part from it in the Forme of a Red Powder, such as was the _Minium_, when it was put to the _Sal Armoniack_. I leave it also to be consider'd, whether in Blood, and divers other Bodies, it be probable, that each of the Corpuscles that concurr to make a Compound Body doth, though some of them in some Cases may, retain its own Nature in it, so that Chymsts [Transcriber's Note: Chymists] may Extricate each sort of them from all the others, wherewith it concurr'd to make a Body of one Denomination.
