![water, f§xvj. ; macerate for two hours and strain.) Dose, f§ss. to f§i. for a child, four times the quantity for an adult. However admin- istered, it should be always followed by a strong mercurial purge. Stanni pulvjs, [U. S.] D. L. E. Powder of Tin. Tin is found in nature chiefly in the form of peroxide, existing in large quantities in Cornwall, in South America, and in the East Indies. Preparation.—The metal is separaled from the impurities which exist with it in the ore, by smelting and liquation. For medical purposes it is reduced to powder, by agitating it while in a state of fusion in a wooden box the inside of which has been rubbed with chalk, (in a mortar previously heated, triturating briskly as its cools, E.), and separating the finerparticles by means of a sieve ; D. E. Physical Properties.—Metallic tin is of a buish-white colour, brilliant, soft and malleable, with but little tenacity ; it emits a slight peculiar odour when rubbed. Sp. gr. 7.3. Chemical Properties.—It melts at 442° F., if the heat be in- creased it oxidises rapidly, and at a red heat burns brightly ; it dissolves slowly in dilute muriatic acid, but rapidly if the acid be strong and boiling ; nitric acid slightly diluted acts on tin with great violence, heat is produced, orange fumes disengaged, and pure peroxide of tin is formed. Adulterations.—Pewter filings are sometimes substituted for tin filings in commerce ; and Christison says, that lead powder is not un- frequently sold for powder of tin. These adulterations may be detect- ed by first acting on the specimen with nitric acid, so as to convert it into the peroxide, boiling the powder thus obtained with distilled water, when, should the tin be pure, the water will not precipitate with so- lution of sulphate of magnesia. Therapeutical Effects.—Powder of tin is a most effectual an- thelmintic, especially for children, in cases of lumbrici, not so useful in cases of ascarides, and producing little or no effect in cases of tamia. It appears to act mechanically, and consequently, its administration should be always followed by an active cathartic. Dose and Mode of Administration.—|ss. to §i. made into an electuary, with an equal quantity of honey or treacle. [Tanacetum [TJ. S] ] Tanacetum vulgare folia, D. Common Tansy. Indigenous ; belonging to the Linnaean class and order Syngenesia Superflua, and to the Natural family Composite (As- teracea. Lindley.) Botanical Characters.—Stem two to three feet high, bearing a corymb of yellow flowers. Physical Properties.—The whole plant has a disagreeable, cam- phoraceous odour, and a nauseous, bitter, aromatic taste. Chemical Properties.—The most important constituents of the plant are bitter resin, and volatile oil. Leroy has recently obtained a peculiar principle from it which he has named tanacetine. Therapeutical Effects.—Though rarely employed in regular practice, it is frequently administered as a vermifuge with much ben- efit as a domestic remedy ; it is only applicable for cases of lumbrici. Dose and Mode of Administration.—In powder, 9i. to 3i- In-](https://iiif.wellcomecollection.org/image/b21143602_0045.jp2/full/800%2C/0/default.jpg)
