A compendious body of chymistry, which will serve as a guide and introduction both for understanding the authors which have treated of the theory of this science in general: and for making the way plain and easie to perform, according to art and method, all operations, which teach the practise of this art, upon animals, vegetables, and minerals, without losing any of the essential vertues contained in them. By N. le Fèbure apothecary in ordinary, and chymical distiller to the King of France, and at present to his Majesty of Great-Britain.

The second Antimonial Precipitate.

℞ As much as you will of well chosen Antimony, grind it to powder and put it in a Matrass, and pour upon it Regulus water two inches high; put the Vessel to digest in ashes, and stir it from time to time to facilitate and advance the dissolution: then draw off the dissolution by decantation very cleanly, or filtrate it in a glass Furnace with Glass grosly beaten: this filtration pour into a Retort, and distil softly in sand to a dry bottom; pour upon the remaining powder distilled Rain-water, and digest it in B. M. un∣til it hath contracted a red Tincture; separate the Tincture, and proceed in the digestion and extraction with new water, until it drawes no more colour; all these Tinctures gather together and filtrate, then draw off the water again in ashes by a slow distilla∣tion in a Cucurbite to a dry bottom: pour upon the remain∣ders very good distilled Vinegar, and extact with it again until it will take no more of the colour; filtrate the Tincture, and throw

away the white remaining feces: draw off the Vinegar in ashes flowly to a dry bottom, or rather to the consistency of a thick Syrup, upon which pour tartarized spirit of Wine; lute well the Vessel with its Blindhead, and put it to digest and extract in the vaporous Balneo during three weeks, and you shall have a faif and red Tincture, which you must filtrate again and throw a∣way the feces; then draw off the spirit of Wine in the slow heat of B. M. to a dry bottom, and you shall have a Powder or Precipitate, which is none of the least preparations which Anti∣mony doth yield. It is a soveraign Remedy against the Pocks and Scurvy; but above all it excels all other things to dissolve con∣gealed blood, and resolve and evacuate all inward Impostumes, and the matter contained in them without any danger. The Dosis must be from gr. ss. to iv. or v. in some appropriated water, or some cordial and stomachical Spirit, or in Bolus in some Con∣fection or Conserve.
