Aloes in any quantity in a mass is hest made up on a hejted slab with proof spirit or decoction of aloes in minute quantity. Butyl Chloral Hydrate should not be treated with the tragacanth paste, which dissolves it and causes the pills to flatten. It is best worked up with a little confection of hips and thick mucilage.

Gallic Acid Si in J drop make a good pill. Iodide of Potassium hould 1* ru: red up with a few drops of water into a smooth paste, and made into a mass with a little liquorice powder ; 6 grs. may thus be got into a fair-sized pill. The pro|»ortions of liquorice and water will dejend upon the sample of iodide, as this salt varies much in its suitability for making pill ina--es. Phosphorus should be dissolved in bisulphide of carbon, and whilst solution is firing effected two or three drops of chloroform may lie added, which produce a heavy va|H>ur around the solution and prevent oxidation of the phosphorus by the atmospheric oxygen. A little liquorice jHiwder is now added, and the mass quickly made into a workable form with Proctor's paste, divided into pills and varnished. Phosphorus is made into a pill by some pharmacists by melting it in cacao butter or mutton suet, and, when cold, beating it into a plastic mass, to which a little powdered liquorice may be added. Quinine H parts, tartarii at iJ I part, with q.s. of Proctor's paste, make a mass much less liable to crumble and of less bulk than if the acid lie omitted. They soon become insoluble. Camphor red with of spirit, Proctor s paste added after the spirit esafiorates. Carbolic Acid may lie easily made into a mass with Ij grs wheaten flour to 2 grs. of the crystallised acid, or with bread crumb, or with powdered marshmallow or elm bark, to which a trace of Proctor's paste is added.
