    separately in two pints of water. Mix the liquors when hot, and let the carbonate of iron subside. Pour off the supernatant liquor, and fre- quently wash the precipitated carbonate, and add to it the sugar dis- solved in two ounces of water ; then evaporate to a powder, which must be kept in a well-closed bottle. The sugar tends to prevent the con- version of the carbonate into the sesquioxide of iron. ) Prop. Greyish-green colour, inodorous, sweetish chalybeate taste. Oper. and Use. As the other salts of iron; but especially adapted for children and delicate women. FERRI IODIDUM. D. E. Iodide of Iron. {Pure Iodine 3j-, Iron filings, separated from impurities by a magnet |ss., Distilled water fjv. Introduce the iodine, iron, and 3j v. of water into a Florence flask, and having heated the mixture gently for ten minutes, boil until the solution loses its red colour. Pass the liquid now through paper into a second flask, washing the filter with the remaining ounce of water, and by means of a well-regulated heat, boil down the liquor until a drop of it taken out on the end of an iron wire, solidifies on cooling. When the flask has assumed the temperature of the air, let the iodide of iron be extracted from it (by breaking the flask, if necessary), and, after it has been submitted to powerful pressure, enveloped in blotting- paper, let it be enclosed in a well-stopped bottle.) Prop. In aggregates of needle-formed crystals, of an iron-grey colour, very deliquescent; taste acrid, metallic. When exposed to the air it is decomposed, and sesquioxide of iron is deposited. Comp. 1 eq. iodine=126*34-1 iron=28+5 water=45, equiv. 199*3. (Fel +5 HO.) Oper. Tonic, emmenagogue, deobstruent. Use. In all cases of debility, in scrofula, incipient cancer, amenorrhcea, secondary syphilis, mesenteric obstructions. A bad form of the pre? paration, which should only be kept in solution. . Dose. Gr. j. to gr. v. in solution. FERRI IODIDI SOLUTIO. E. Solution of Iodide of Iron. (Iodine gr. 190+ Clean Iron wire gr. 100, Distilled Water fjvj. Preserve the solution with iron wire in the bottle.) Use. The same as the iodide. Dose. Htxl. tof3j. FERRI MURIATIS TINCTURA. E. See Tinctura Ferri Sesqui- FERRI OXIDUM MAGNETICUM. D. Black Oxide of Iron. (Sul- phate of Iron 3xij., Solution of Caustic Potash 31 jv., Distilled water, a sufficient quantity.) Use. In the same cases as the rust. Dose. Gr. v. to 3j. FERRI OXIDUM NIGRUM. E. Black Oxide of Iron. (Sulph. of Iron 3jv., Sulph. Acid f.3ij. and f3ij., Nitric Acid f3jvss., Aqua Am- monia fgjvss., Boiling Water Oiij.) Use. The same as the sesquioxide of iron. FERRI OXIDUM RUBRUM. E. Ferri Peroxidum, D. Ferri Ses- quioxidum, L. See Oxidum Ferri Rubrum. FERRI PERNITRATIS LIQUOR. D. Solution of the Pernitrate of Iron. Persesquinitrate of Iron. (Fine iron wire free from rust 3j., Pure Nitric Acid fBiij-* Distilled Water, a sufficient quantity. Into the acid, first diluted with f3xvj. of the water, introduce the iron wire, and leave them in contact until gas ceases to be disengaged. Filter the solution, and to it add as much water as will make its bulk a pint and a half. Sp. gr. 1107.) Comp. The pernitrate is composed of 2 atoms of peroxide of iron, 3 of nitric acid, 1| of water. (Pelouze.) (2 Fe20\ 3 NO5 1| HO.) Prop. Orange-brown, clear, nitric a id odour, and styptic taste. Oper. Tonic, astringent. Use. In chronic, lienteric, and phthisical diarrhoea, in mesenteric dis- ease, mucous vaginal discharges.
