The Volatile Salt of Tartar, as I have often made it, which is an Excellent Re∣medy.
TAke Lees of Wine, (which you may have from the Wine-Coopers when they have pressed them out for making of Vine∣gar) break them in small pieces, and let them dry; then being very hard and dry, bruise them grosly, and fill an Earthen Re∣tort with it, or a Glass one coated; distill in naked fire, fitting any Recipient to it to receive only a sour flegm, which will come over first; as soon as you see any white fumes come over, (among which cometh the Vo∣latile Salt) change the Recipient, putting on another pretty large; lute the junctures well with Paste and Paper, then increase the fire by degrees, until you see the Recipient filled with white fumes; continue the fire in that degree, untill those white Vapours diminish, and that the Recipient beginneth to grow cold: Then augment the fire to the highest degree, to force all over at last; when nothing more cometh over, cease. The distillation will be performed in three or four hours; you will have a whitish Liquor, which contained in it the Volatile Salt, and part thereof will stick to the sides of the Recipient,
