    LOCAL THERAPEUTICS. blown through the tube by a rubber hand-ball carrying the vapor with it Walter G. Smith ^Br. Med. Jour., May 7, 1881) has likewise used this apparatus with satisfaction. Diseases of the Ear, Nose, and Throat.-Calomel hasa reputa- tion second only to that of the bichloride in the treatment of Otorrhcea Ihe parts should be first washed out thoroughly with a solution of bichlo- ride of mercury and the calomel used subsequently as an insufflation {Year Book of Treatment, 1885). Black wash is often employed as a remedy for Eczema of the auricle. Calomel in the proportion of five to eight grains to an ounce of powdered sugar or bismuth subnitrate, is a favorite remedy with many practitioners for inflammatory states of the interior of the nose. It is especially indicated in Chronic Purulent Catarrh of children and in Syphilis. Calomel is of repute in the local treat- ment of Diphtheria. The powder may be floated on a teaspoonful of cold water and the whole conveyed to the open mouth. While the bulk of the powder adheres to the sides of the tonsils and pharynx a small portion will be swallowed. This method of treatment has been popu- larized by W. H. Daly {Trans. American Laryngological Ass'n, 1889). A similar treatment is efficacious in the treatment of Croup. Thrown upon the vocal cords by insufflation, calomel has been found useful by Tchernoff {St. Olga's Hospital Reports, 1888, p. 19) for Syphilitic Laryngitis. Diseases of the Eye.—Calomel is a valuable local application in Phlyctenular Ophthalmia, though, as it is insoluble, the rationale of its action is not easily understood. That it is something more than a mechan- ical irritant has been shown by experiments in which inert powders were substituted without producing the same effects. It is used as a fine, dry powder, and is dusted directly upon the ulcer from a camel's-hair brush. The brush is held between the forefinger and thumb and flicked with the little finger of the same hand. Calomel should not be used when there is much ciliary irritation, shown by photophobia, lachrymation, and contracted pupil, but after this has been subdued by atropia and other remedies. It is also useful in Chronic Vascular Keratitis and Pannus, and in small indolent Ulcers and Superficial Opacities (nebula) of THE Cornea. HYDRARGYRI lODIDUM RUBRUM. Red Iodide of Mercury. Biniodide of Mercury. Mercuric Iodide. A scarlet-red, crystalline powder, permanent in the air, odorless and tasteless, almost insoluble in water, soluble in 130 parts of alcohol at 15° C. (59° F.), and in 15 parts of boiling alcohol; also soluble in solutions of iodide of potassium or of mercuric chloride. (U. S. P.)
