    action of the Sugar in this and other similar cases is, that it prevents oxidation. (Klauer supposed that a definite compound is formed con- sisting of Protoxide and Sesquioxide of Iron, Carbonic acid. Sugar, and Water. He found 80 of Protoxide to 20 of Sesquioxide.) Fifty grains ought to yield 7*5 cubic inches of gas when decomposed by an acid. The B. P. states that the solution in HCl is but slightly affected by the Ferrocyanide, but gives a copious blue precipitate with the Ferridcy- anide of Potassium. It contains at least 57 per cent, of Carbonate. 20 gr. dissolved in excess of HCl, and diluted with water^ continue to precip. Ferridcy. Pot. until at least 33 measures of the volum, sol. Bichromate of Potash have been added. Action. Uses. Used, as the rest, in Anaemia, and the disorders associated with it. An excellent form of a Ferruginous preparation. D. gr. X.—gr. XXX. PiLULA Ferri Carbonatis, B. Pill of Carbonate of Iron. Prep. Saccharated Carbonate of Iron ^j., Confection of Eoses ^J. This pill is stable in composition, and contains a little less than half its weight of the Protocarbonate of Iron. The compound iron pill of the L. P., made by mixing Sulph. Iron with Carb. Soda, Myrrh, and Treacle, did not contain enough sugar to prevent decomposition. D. gr. v. or gr. x.—xx. 2 or 3 times a day. The Pilules de Vallel are similar to the pill of the L. P. Pilules de Blaud are made with Carb. Potash and Gum Arabic, and are a close imitation of the following mixture. MiSTURA Ferri Compostta, B. Compound Mixture of Mars. Griffiths Antihectic or Tonic Mixture. Prep. B. Rub powdered iJ/^/^r/i gr, Ix with Spirit of Nutmeg'^., Sugar gr.lx., and Card. Potash gr. xxv., add Rose Water jvij. gradually, an<i then Sulph. Iron in powder gr. xxx., previously dissolved in ^j. of Ease Water. Put the mixture immediately into a well-stoppered bottle. This is somewhat stronger than the mixture of the L. P., which it otherwise resembles. The Sulphate of Iron is decomposed, and Carbo- nate of Potash being employed, we have a Sulphate of Potash left in solution. A hydrated Protocarbonate of Iron is suspended with Myrrh and the Spirit of Nutmeg as aromatics, while the Sugar assists in pre- venting the formation of Sesquioxide of Iron. Mr. Brande states that the best mode of making it is to triturate a fine piece of Myrrh into an emulsion with rose-water, add the Carbonate of Potash, Nutmeg, and Sugar, and lastly dissolve in it the Sulphate of Iron. If the bottle is kept full, the preparation will long remain unchanged : it should there- fore be prescribed in draughts. (Ince, P. J. i. 252.) Inc. Acids and Acidulous Salts, Vegetable Astringents. D. fjj.—fjj. 2 or 3 times a day. Soubeiran (ii. p. 434) describes some other preparations of the Carbo- nate of Iron, as the Poudre Ferrugineuse, in which Bicarb. Soda and Sulphate of L'on are mixed with Sugar, also Poudre Feree Gazeuse. The latter is exhibited as follows :
