Take what quantity you please of sweet Sublimate, reduce it to Powder in a Marble or Glass-Mortar, and put it into a Matras, three quarters whereof remain empty, and of which you have cut off the Neck in {179} the middle of its Height: Then place this Matras in a Furnace or _Balneum_ of Sand, and make a little Fire underneath for an Hour, to give a gentle Heat to the Matter, which may be augmented by little and little to the third degree: Let it continue in this state about five Hours, and the Matter will be sublimated within that space of time. Then let the Vessel cool, and break it, throwing away as unprofitable a little light sort of Earth, of a reddish Colour, which is found at the bottom, and separating all the Sublimate from the Glass. Afterward pulverize it a second time, and let it be sublimated in a Matras, as before: Thus the Sublimations must be reiterated seven several times, changing the Matrasses every time, and casting away the light Earth. Then having reduc'd your Sublimate to a very fine impalpable Powder, by grinding it upon a Porphyry or Marble Stone, put it into a Glass Cucurbite or Gourd, pour into it alkaliz'd Spirit of Wine to the height of four Fingers; cover the Cucurbite with its Head, and leave the Matter in Infusion during fifteen Days, stirring it about from time to time with an Ivory _Spatula_. Afterward set your Cucurbite in _Balneo Mariæ_, or in a Vaporous Bath, make fit a Recipient to the Mouth of the Alembick; lute the Joints exactly with a moistened Bladder, and cause all the Spirit of Wine to be destill'd with a moderate Fire: Let the Vessels be cool'd, and unluted, and the _Panacæa_ will appear at the bottom of the Cucurbite. If it be not {180} already dry enough, you may dry it up with a gentle Fire in the Sand, stirring it with an Ivory or Wooden _Spatula_ in the Cucurbite it self till it be reduc'd to Powder. It may be kept for use in a Glass-Vessel, as a Remedy of very great Efficacy for all sorts of Venereal Diseases, as also for Obstructions, the Scurvy, _Scrophula_ or Kings-Evil, Tettar, Scab, Scurf, Worms, _Ascarides,_ inveterate Ulcers, _&c._ The Dose is from six Grains to two Scruples, in Conserve of Roses. * * * * * {181} A TREATISE OF THE DISEASES OF THE BONES. * * * * * CHAP. I. _Of the Dislocation of the Bones._ _What are the Diseases incident to the Bones?_ They are five in number, _viz._ Dislocation, Fracture, _Caries_ or Ulcer, _Exostosis_, and _Nodus_. _What is a Dislocation or Luxation?_ It is the starting of the Head of one Bone out of the Cavity of another, with an {182} Interdiction of the proper Motion of the Part: Or else it is the disjointing of two Bones united together for the Motion of a Part. _How many causes are there of Dislocation in general?_
