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 Menstruum.

THis Menstruum is ordinarily called Aqua temperata, tempe∣rate Water, as also the sweet or dulcified spirit of Salt: for it is made of equal parts of very pure Alkoholiz'd spirit of Wine and spirit of Salt very well dephlegmated, which you must mix to∣gether by degrees; then distill and bring over the Helm in ashes four or five times, or what is yet better, until they be inseparably conjoin'd and united together by reiterated distillation: this being performed, you shall have a very good preservative and curative of the Plague and all contagious diseases, because it hinders all manner of corruption, preserves the natural parts in their equal temper and necessary vigour; this also is the Menstruum which shall be us'd to keep in it self the internal sulphur of Coral, which the first Menstruum did yet hide, or the shadow of the Body.
