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 ancient way of preparing your acetous Syrup, or the com∣pounded Syrup of Vinegar.

℞ Roots of Fennel, Smallage and endive, or Chicory ana ℥ iij. of the Seeds of the same ana ℥ i. except Endive ℥ ss. boyl all, shred and reduce it to a gross Powder in lb x. of Spring-water with a slow fire, to the consumption of one half, then in an Earthen Vessel glazed; reduce it to a Syrup with lb iij. of Sugar and lb ij. of very strong Vinegar: We have the same reasons to take and note the Errors, whereof was spoken above: For, who cannot (I beseech you) perceive the gross and plain absurdities herein ob∣vious, to boyl Seeds and Roots, compounded of Volatile and subtile parts, with a slow fire, and lb x. of water: and moreover, to joyn two pound of Vinegar to lb v. of liquor, to destroy the most penetrative and active part of it, and upon whom depends all the incisive and aperitive vertue of this Syrup. Let us not grow tedious nevertheless, in repeating so often the same lesson: but show the way and means how to do better, since we have suffici∣ently explicated this matter here above in our preceding Notes up∣on the plain acetous Syrup.
