![Uses.—In dyspepsia with pain, combined with bismuth or sodium ] bicarbonate. To allay vomiting and cough. It is very useful as a sedative in an effervescing mixture, and as a 2% dilution as j lotion to soothe the itching of pruritus ani or pruritus vulvse, or r general prurigo. Must not be used to broken skin surface. To promote healing of acute gastric ulcer bismuth, according to (some, is of no particular value, but dilute hydrocyanic acid 5 minims in two drachms water is useful for vomiting. 3 CE)Lotio Acidi Hydrocyanic! cum Sodio, L.H. Diluted Hydrocyanic Acid 8-3, Borax 9'2, Sodium Bicarbonate ; 9'2, Water to 1000. As a soothing eye lotion.—R.O.H. has 1% of each. ACIDUM HYPOCHLOROSUM. HC10 = 52*468. Hvpochlorous Acid, as such, has not been isolated. In solution iand especially in the form of its salts—the Hypochlorites, e.g. those of Calcium and Sodium, it has played an important part in many chemical processes. The method of treating Chloride of Lime with Boric Acid in excess, as advocated during the war, was recognised in the past as a method of making solutions of Hypochlorous Acid. The acid in dilute solution is practically colorless; in a concen¬ trated form it is yellowish. It readily undergoes decomposition with formation of chlorine, chloric acid, oxygen and water. It is hence a strong oxidising agent and for this reason a bleaching agent. Medicinally the Chlorinated Soda Solution was a popular detergent during the last half century, but has latterly fallen into dissuetude. The Hypochlorites were, however, resuscitated and were extensively employed for wound treatment in the war as described in the fol¬ lowing pages. Calx Chlorinata. (Off.) Sel de Javelle. A dull white powder having about 30% available Chlorine. Solutions of 0*25 to 0*5% applied to burns and ulcers heal them rapidly. The best commercial samples do not contain more than 70% of Calcium Chloro-hypochlorite (CaOCb).—J. McCrae, P.J. i./2o,273, i.e. 39% available Chlorine. 25,000 gallons of water can be sterilised for less than Id. by aid of Calx Chlorinata.—Thresh, L. ii./oS, 1597,1846. Water sterilisation with Calcium Hypochlorite for troops on active service.—Sims Woodhead, B.M.J. ii./i4,494 Chlorination of Potable Water. 1 ounce of Chloride of Lime to 2000 gallons. Remove taste by a few crystals of Sodium Hyposulphite.— Ministry of Health Circular, L. ii./2i,671. cf. also Yol. it. Unguentum Calcis Chlorinatae. Chilblains can be cured with 10% strength in Paraffin Ointment. Gonococcal arthritis in women has been treated by vaginal douch¬ ing twice daily with solution of calx chlorinata 1 in 100. Afterwards a solution of Hydrogen Peroxide is freely used.](https://iiif.wellcomecollection.org/image/b31360440_0001_0093.jp2/full/800%2C/0/default.jpg)
