Disinfectin.—(Pharm. Zeitschr. f. Russl.) Disinfectin is the name of a preparation intended for ordinary disinfection, said to be obtained as follows: 5 parts of the residue left in distilling crude naphtha are thoroughly mixed with one part (by volume) of concentrated sulphuric acid, and allowed to cool. The fluid portion is separated from the sediment, and gradually mixed with an equal volume of ten per cent. soda solution, and well shaken. Thus is obtained a yellowish-brown emulsion,—disinfectin,—which, when intended for use, is diluted with four parts of hot water, and thoroughly shaken.—Amer. Med. Surg. Bulletin.
Hippuric Acid as a Diuretic.—This acid, obtained[[1]] from the urine of the cow, is a favorite diuretic with many French practitioners. Dujardin-Beaumetz prescribes it combined with lime:
| ℞ | Hippuric acid | 25 grammes |
| Milk of lime sufficient to neutralize it. | ||
| Simple syrup | 500 grammes | |
| Essence of lemon to flavor. |
Four to six tablespoonfuls daily. As before mentioned it is excreted in the urine as benzoic acid.—Provincial Medical Journal.
Thymol in Toothache.—Dr. Hartmann (Deutsche Med. Wochenschrift) has employed thymol in toothache from hollow teeth, in place of arsenious acid. He fills the cavity of the tooth with a tuft of cotton on which a few crumbs of thymol have been sprinkled. It does not irritate the mucous membrane of the mouth much, and it is easily removed by rinsing the mouth with water. If a rapid action is desired let the patient rinse the mouth often, with warm water, in order to facilitate the solution of the drug. It never increases the pain at first, as arsenic does, and is not poisonous.—Lancet-Clinic.
