    or mixed with collodion (i to 3), which it coagulates, or triturated with 3 parts of camphor to form Phenol-Camphor. A mixture of carbolic acid, i part; castor oil, 4 parts; and almond oil, 15 parts (Lund's Oil), is used for lubricating catheters, which should previously have been sterilised in aqueous phenol (i to 20). The so-called Phenol lodatum (10 per cent.) is occasionally used as a local application. Carbolic acid cannot be made into pills with camphor, thymol, menthol, resins, and gum-resins without the use of much absorbent powder; it is also incompatible with free ammonia and ammonium salts, ferrous salts, and lime. In cases of poisoning by carbolic acid, saccharated solution of lime, solution of magnesium or sodium sulphate, or olive or camphorated oil should be administered, 120 mils (4 fluid ounces) of camphorated oil forming a valuable antidote and stimulant. Heat should be applied to the extremities, and alcoholic stimulants given. Carbolic acid burns may be treated by the application of olive oil, lime water, or vinegar. Dose.—i to 2 decigrams (i to 3 grains). Note.—Carbolic acid sometimes acquires a pink colour on keeping, especially if exposed to moist air, owing to the formation of some coloured derivative from traces of impurities present. ACIDUM CARBOLICUM LIQUEFACTUM. Liquefied Carbolic Acid. Synonyms.—Liquid Carbolic ; Liquefied Phenol. Carbolic Acid, in crystals 90*00 Distilled Water, by weight g'oo Add the water to the carbolic acid, heat gently until the crystals melt, and mix. Liquefied carbolic acid is a colourless or pinkish product, and should form a clear solution on the addition of 18 to 27 per cent, of water at 15-5°. Specific gravity, i-o54 to 1-069. The boiling- point of the liquid rises gradually to a temperature not higher than 182°. Dose.—^ to 2 decimils (i to 3 minims). , Notes.—Carbolic acid is liquefied by the addition of 8 per cent, of water, but the resulting liquid, like the official liquefied phenol, solidifies when kept under ordinary conditions in cold weather. If 12 per cent, of water be used the liquid does not solidify so readily. Phenol Liquefactum, U.S.I ., contains 86-4 per cent, by weight of absolute phenol, and its specific gravity is about i ob5 at 25°. ACIDUM CHROMICUM. Chromic Acid. CrO„ = loo-i. Synonyms.—Chromic Anhydride ; Chromium Trioxide. Chromic anhydride, CrOg, may be prepared by adding sulphuric acid to an aqueous solution of potassium bichromate. It occurs in deliquescent, dark red, needle-shaped crystals. Very soluble in water (2 in i). Melting-point, 192°. It usually con-
