    This agent has long been one of the remedies generally relied upon in the local treatment of Diphtheria. Lunin, in 1882, found the best results following its use. A convenient form is to add one drachm of the tincture to two ounces of syrup. This can be given as an internal remedy, but the tenacious character of the mucus causes the remedy to cling to the walls of the pharynx and thus, pressing downward, secures a local appli- cation W. Porter {^Trans. Amer. Laryngological Ass'n, 1887) advocates a much stronger preparation-namely, equal parts of the tincture with glycerin. The application should be made every two or three hours. Chloride of Iron Wool : Cotton-wool, one drachm ; glycerin, ten minims; tr. fer. chlor., one ounce. Mix the glycerin with the tincture, saturate the wool with the liquid, and dry. FERRI ET AMMONII SULPHAS. Sulphate of Iron and Ammonium. Ferric Alum. It occurs in pale violet, octahedral crystals, efflorescent on exposure to air, odorless, having styptic taste and a slightly acid reaction. Soluble in three parts of water at 15° C. (59° F.) and in eight-tenths part of boiling water; insoluble in alcohol. (U. S. P.) Sulphate of iron and potassium is also sold under the name of « ferric alum. Ferric alum is a powerful astringent. General Surgery.—Ferric alum often substitutes alum in practice, as it is n'lore astringent. It is devoid of the stimulating effects of the iron salts. It is in requisition as a vaginal wash in the treatment of Leucor- RHCEA and Vaginitis. A saturated hot solution may be employed as a hgemostatic. Diseases of the Ear, Nose, and Throat—Keene recommends a solution of eighty grains to the ounce for Chronic Laryngitis. In a solution of four grains to the ounce of water ferric alum is a useful astringent in Chronic Nasal Catarrh. It stains linen, and on this account is not so popular as are some other forms of astringents. In the strength of three grains to the ounce it may be used as a spray in Pharyn- gitis and Laryngitis. FERRI SUBSULPHAS. Monsel's Salt. Basic Ferric Sulphate, Fe40(S04)5- It occurs in the form of thin, transparent scales, is of a reddish-brown color, very deliquescent, and very soluble in water. (U. S. D.) There is official, in the United States Pharmacopoeia, a liquor ferri subsulphatis which contains forty-three and seven-tenths per cent, of the salt. It is usually known as Monsel's solution, from M. Monsel, who first called attention to its properties as a styptic, in 1852. A hsemostatic absorbent cotton is prepared by steeping absorbent cotton in solutions of subsulphate of iron forty-five per cent.
