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 first Precipitate of Antimony.

℞ As much as you will of well chosen Antimony, make it into course powder, and throw it in a long, broad neck Ma∣trass, and by little and little pour upon it good Regal water, agi∣tating and stirring sostly the matter, until the Menstruum goes a∣bove it three fingers high, but take care in the working of the Dissolvent; put the Vessel to digest in ashes in an equal heat, until you see the Antimony fallen to the bottom in the form of

a white Calx; then pour all into a Retort, and draw off the Regal water by distillation in sand, until the said powder in the bottom becomes very dry; then digest it in distilled Rain-water, and edulcorate it well with new water, then dry it gently; after this, having put the same in a Crucible, reverberate it for the space of six, seven or eight houres, or until the colour be changed and exalted into a red: if you will spare fire and labour, you may put this Calx in a Crucible covered and well luted, and put it in a Potters Furnace to reverberate during the time his work is a ba∣king. This Precipitate doth very happily and successefully purge the yellow and mordicant, or harsh serosities, lurking for the most part in the bottom of the stomach and adjacent parts, which it does very well both upwards and downwards, not that it is of it self violent or purging: for it doth otherwise operate in those that are not stuft with those superfluous serosities, and have no vice or defectuosity in the fermentation of the Ventricle: for it works with them by Sweats, Urine, or insensible transpiration. The Dosis may be from gr. j. to viij▪ in cordial Conserves, or gelly of some. Fruit.
