    AcHDUM FiroEicuM DiLUTUM. T. H. An aqueous boIu- tion of hydrofluoric acid gas, obtained by passing the gas produced by the action of sulphuric acid on fluor spa, into water. The commercial acid thus prepared is redis- tilled for therapeutic use. The redistilled acid contains about 30 per cent, of fluoric acid. A half per cent, solu- tion of the redistilled acid is kept in glass bottles for use; the dose of the latter is from 20 to 60 minims. AciDTJM FOHMICUM. Exists naturally in ants. Obtained by the action of binoxide of manganese and sulphuric acid on starch. Formerly given in chronic rheumatism. Acid Gallicum. B. Boil one part of coarsely powdered galls with four fluid parts of diluted sulphuric acid for half an hour, then strain through calico while hot; collect the crystals that deposit on cooling, and purify these with animal charcoal and repeated crystallization. B. 1867. Place galls in coarse powder ibj in a porcelain dish, pour on as much distilled water as will convert them into a thick paste, and keep them in this moistened condition for 6 weeks, at a temperature of between 60° F. and 70° F., adding distilled water from time to time to supply what is lost by evaporation. At the end of that time boil the paste for 20 minutes with f^xlv of the water, strain through calico, and when the fluid has cooled, col- lect on a filter the crystalline deposit which has formed, and let it drain. Press it strongly between folds of filter- ing paper, and redissolve in gx of boiling distilled water. When the fluid has cooled to 80° F. pour it off from the crystals which have formed, wash these with of ice- cold distilled water, and dry them, first by filtering paper, and finally at a temperature not exceeding 100° F. By boiling the undissolved portion of the galls with an addi- tional gxlv of water, filtering into a capsule containing the liquor decanted from the crystals in the preceding pro- cess, evaporating to the bulk of Jx, and cooling to 80° F., an additional quantity of acid may be obtained, which, however, is usually a little darker in colour than the pro- duct of the previous crystallization. Dose, 2 to 10 grains. AciDTJM Htdeiodicum. Dr Buchanan's Medicinal Sy- driodic Acid is made by dissolving sepai'ately 264 gr. of tartaric acid and 330 gr. of iodide of potassium, each in l5iss of distilled water. Mix the solutions, agitate, and, when settled, decant the clear liquid, adding water to
