Take then of good Antimony, Salt-Petre and Tartar, of each an equal weight, and of Quicklime Halfe the Weight of any one of them; let these be powder'd and well mingl'd; this done, you must have in readiness a long neck or Retort of Earth, which must be plac'd in a Furnace for a naked Fire, and have at the top of it a hole of a convenient Bigness, at which you may cast in the Mixture, and presently stop it up again; this Vessel being fitted with a large Receiver must have Fire made under it, till the bottom of the sides be red hot, and then you must cast in the above prepar'd Mixture, by about halfe a spoonfull (more or less) at a time, at the hole made for that purpose; which being nimbly stopt, the Fumes will pass into the Receiver and condense there into a Liquor, that being rectifi'd will be of a pure golden Colour, and carry up that colour to a great height; this Spirit abounds in the Salt I told you of, part of which may easily enough be separated by the way I use in such cases, which is, to put the Liquor into a glass Egg, or bolthead with a long and narrow Neck. For if this be plac'd a little inclining in hot sand, there will sublime up a fine Salt, which, as I told you, I find to be much of kin to the Volatile Salts of Animals: For like them it has a Saltish, not an Acid Salt; it hisses upon the Affusion of Spirit of Nitre, or Oyle of Vitriol; it precipitates Corals Dissolv'd in Spirit of Vinager; it turnes the blew Syrup of Violets immediately green; it presently turnes the Solution of Sublimate into a Milkie whiteness; and in summ, has divers Operations like those that I have observ'd in that sort of Salts to which I have resembled it: and is so Volatile, that for Distinction sake, I call it _Tartari Fugitivus_ [Errata: Sal Tartari Fugitivus]. What virtues it may have in Physick I have not yet had the opportunity to Try; but I am apt to think they will not be despicable. And besides that a very Ingenious Friend of mine tells me he hath done great matters against the stone, with a Preparation not very much Differing from ours, a very Experienc'd Germane Chymist finding that I was unacquainted with the wayes of making this salt, told me that in a great City in his Country, a noted Chymist prizes it so highly, that he had a while since procur'd a Priviledge from the Magistrates, that none but He, or by his Licence, should vent a Spirit made almost after the same Way with mine, save that he leaves out one of the Ingredients, namely the Quick-lime. But, continues _Carneades_, to resume my Former Discourse where your Curiosity interrupted it;
