Glass or Earthen Retort two thirds full; put it into a Fur∣nace over a very gentle Fire, both to heat the Retort, and drive out the Flegm, (which comes first:) continue this de∣gree of Fire, till the drops be∣gin to have some taste; then fit to it a large Receiver, lute well the Junctures, and increase the Fire gradatim, so will the Spirit come forth, filling the Receiver with Clouds: all be∣ing come off, let the Vessels cool, then unlute, and take the Spi∣rit and put it into a Glass Cu∣curbit, to rectifie it, in a very gentle Sand heat, drawing off about the one half thereof: this is the inflamable Spirit of Saturn, burning like Spirit of Wine, and of a sowre taste, Quemque inter non entia re∣ponit Rolfincius; but I think him to be mistaken. § 2. The other half of the Liquor which remains in the Alem∣bick, they call (tho' impro∣perly) Oyl of Saturn, and is used to cleanse and clear the Eyes of Horses. § 3. The blackish matter remaining in the Retort, being put into a Crucible upon a good Fire, will reassume the form of Lead, being deprived of the Acids which gave it the form of Salt. § 4. The Salt of Sa∣turn may also be revived into Lead, by mixing it with an Alcaly, and melting it as a∣foresaid in a good Fire, for that the Alcali absorbs the Acid, and as much enervates it, as if it were drawn off; but then it will flame, before it revives, because of the Spirit of Wine contained in the Vinegar, which convert∣ed the Lead into Ceruse. § 5. The Spirit of Saturn there∣fore is inflamable, because it contains some Spirit of Wine, which remains still involved in the Vinegar, and was car∣ried with the Acids into the Pores of the Lead, when the Saccharum Saturni was made. This Salt being distilled, the force of the Fire breaks the Acid, and sets the Spirit of Wine at liberty; so that the Spirit of Saturn has very lit∣tle of an acid taste in it. § 6. It is also to be observed, that if you take lbj. or ℥xvj. of the Saccharum, you will have by distillation in the Retort, about 3¼ ounces of Liquor, or Spirit, and yet there will be left in the Retort (which is the wonder) about eighteen ounces of a blackish matter, so that here an augmentation is evident: Now 〈 math 〉〈 math 〉the quantity of Lead in the Saccharum: And if you re∣duce the eighteen ounces of black Matter into Lead, in a Crucible, you will have of
