![i^xxviij., E.); digest for seven (fourteen, L.) days, and filter.) Ca- thartic and tonic. Dose, min. xxx. to fgss.—Tinctura Aloes comp., D. L. Tinctura Aloes et Myrrhce, E. (Socotrine (or East In- dian. E.) aloes, powdered, ^iij. (jiv., L. E.); tincture of myrrh, by measure, ibij. (Oij.; and saffron, gij., L. E.) ; macerate for fourteen (seven, E.) days, and filter.) Stomachic and cathartic. Dose, i'3ss. to f3ij.—Enema Alo'ts, L. (Aloes, 3ij.; carbonate of potash, gr. xv.; decoction of barley, Oss.; mix, and rub them together). A useful stimulating cathartic in the constipation of amenorrhcea; also employed for dislodging ascarides from the rectum. Calomelas, E. Calomelas sublimatum, D. Hydrargyri chlo- ridum, L. [Hydrargyri Chloridum Mite, U. S. P.] Calomel; Sublimed Calomel; Chloride of Mercury. {Sub-chloride of, Mer- cury, Graham.) Calomelas fr/Ecipitatum, D. Calomel by precipitation. P. P.—Calomel, as obtained by sublimation, is sometimes in the form of a semitransparent, white, crystalline cake, the crystals be- ing four-sided prisms ; as usually met with, however, it is a heavy, snow-white, soft powder, inodorous and tasteless. Its sp. gr. is 6'5 (Graham). C. P.—Calomel is a subchloride of mercury, being composed of 1 eq. of chlorine and 2 of mercury (Hg2Cl.). It is completely in- soluble in cold or boiling distilled water, in alcohol, or in ether. It acquires a yellow tinge by exposure to the air or by rubbing; exposed to heat, it becomes yellow, and volatilizes at a heat below redness; if under pressure, it fuses ; with lime-water it gives a black- ish precipitate, sub-oxyde of mercury. Prep.—Calomelas sublimatum, D. Persulphate of mercury, 25 parts ; purified mercury, 17 parts ; muriate of soda, dried, 10 parts; triturate together in an iron mortar the persulphate and the purified mercury, till the metallic globules shall Have completely disappeared, then add the dried muriate of soda; mix well, and in a suitable vessel, with a gradually-increased heat, sublime into a receiver ; reduce the sublimed mass to powder, and wash it with water, as long as the decanted liquor precipitates with solution of caustic potash; finally, dry the sublimed calomel,— Hydrabgyri c'iilouiiium, L. .Mercury, Ibiv. ; sulphuric acid, lbiij. ; chloride of so- dium, fbiss. ; distilled water, a sufficiency. Boil Ibij. of the mercury with the sul- phuric acid in a proper vessel, until the bipersulphate of mercury remains dry ; rub this, when it is cold, with Ibij. of mercury in an earthen mortar, that they may be perfectly mixed. Afterward add the chloride of sodium, and rub them together until globules are no longer visible ; then sublime. Rub the sublimate to very fine powder, and wash it carefully with boiling distilled water, and dry it.—Calomel ls, E. Mercury, ?viij.; sulphuric acid, ffij., fjiij. ; nitric acid, f^ss.; muriate of soda, fiij. ; mix the acids, add to them ^iv. of the mercury, and dissolve it with the aid of a moderate heat ; raise the heat so as to obtain a dry salt. Triturate this with the muriate of soda and the rest of the mercury, till the globules entirely disappear ; heat the mixture by means of a sand-bath in a proper subliming apparatus. Reduce the sublimate to tine powder, wash the. powder with boiling distilled water until the water ceases to precipitate with solution of hydriodate of potash ; and then dry- it.—Calomelas prjECIpitatum, D. Purified mercury, 17 parts; diluted nitric acid, 1.5 parts ; pour the acid upon the mercury, put into a glass vessel, and as soon as the mixture ceases to effervesce, digest with a gentle heat for 0 hours, frequently agitating; then increase tb.e heat, that the liquor may boil lor a shorl nine, pour off from the residual mercury, and mix the liquid immediately with a solution of 7 parts of muriate of soda in WO parts of boiling water; wash the precipitated pow- der with warm distilled water, as long as the poured-off liquor is affected by solu- tion of caustic potash ; finally, dry the powder.
