_How to make good spirit and oyles out of Pearls, Corals, Crabs-eyes, and other light soluble stones of beasts and fishes._ Take to one part of pearls or corals (made into fine powder) three or four parts of pure Tartar, and so much water as will dissolve the Tartar by boyling; put the corals, Tartar and water together into a glass body, which must stand in sand, and give it so strong a fire, that the water boyl in the glass body with the Tartar, and may dissolve the corals. (This solution may be done also in a clean earthen pot that is glased, and the evaporated water must be supplyed with other, as above was taught to be done with the metals.) The corals being dissolved, let them cool, filtrate the solution, and abstract all the moisture from it in Balneo, and there will remain a pleasant honey-thick liquor, which may be used in Physick either of it self, or else once more extracted with spirit of wine and purified, or else distilled, as you please. The extract or Tincture is better than the liquor, and the spirit is better than the extract or tincture: and all three may well and safely be used; they strengthen the heart and brain; especially those which are made of pearls and corals, they expel the urin and keep the body soluble. Those of crabs eyes and of pearches and other fishes open and cleanse the passages of the urin from all slime and impurity, and they powerfully expel the stone and gravel in the reins and bladder. N. B. The distilled spirit of corals being well rectified, is good for the Epilepsy, Melancholy, and Apoplexy. It expelleth and driveth out all poyson by sweating, because it is of a golden nature and quality, whereof in another place more shall be said. _To distill a spirit out of salt of Tartar and crude Tartar._ If you take a like quantity of crude Tartar and of salt of Tartar, and dissolve it with clean water, and then evaporate the water still skimming it, till no skin more do rise, and then let it cool, there will shoot white crystals, which being distilled as common Tartar, they will yield a purer subtler and pleasanter spirit, than the crude Tartar doth, in all to be used as above hath been taught of the simple spirit of Tartar: therefore it is needless here to describe its use. Before you distill a spirit thereof, you may use them in stead of _Tartarus vitriolatus_ for purging, they will cause gentle stools, and drive also the urin and stone, and are not unpleasant to take. The dose is from ℈ i. to ℥ i. in waters fit for your purpose. This salt dissolved with water purifieth metals (if they be boyled therein) and maketh them fairer then common Tartar doeth. _How to get a powerful spirit out of the salt of Tartar, by the help of pure sand or peble-stones._
