    As a parasiticide, a lotion of one grain of the bichloride to an ounce of vinegar destroys Pediculus Pubis and Pediculis Capitis, and, at the same time, the ova of these parasites, which cling to the hairs. In Tinea CiRCiNATA and in small patches of Tinea Versicolor a solution of two to four grains of the bichloride in an ounce of the compound tincture of benzoin, painted on the affected parts once or twice a day, as recommended by Taylor of New York, is efficacious. A solution in dcohol of similar strength may be painted on the smaller patches of Ringworm of the scalp. Recently electricity, applied from the negative pole of a constant current battery has been employed to facilitate the penetration of this parasiticide. Such applications should be made cautiously, and not over too large a surface at any one time for fear of absorption with toxic effect. In Erysipelas, Eppstein {Therap. Monatshefte, No. 4, 1891) has used a one per cent, ointment of this salt in lanolin with excellent results. White, of Boston, has recommended the employment of an ointment of ten to forty grains of bichloride of mercury to the ounce of lard, or of a ' solution of similar strength in castor oil as an application in Lupus Vulgaris. A mixture of bichloride of mercury with creasote has been described under the latter head. It is an efficient application in Lichen Planus and Lichen Ruber. Bichloride of mercury enters into the composition of a famous lotion formerly, and still to some extent, employed in the treatment of Acne, under the name of Gowland's lotion. It is composed as follows: R. Hydrarg. bichlor., gr. vij; alcoholis, in^xx; misturse amygdalae, ad fgiv. M. Diseases of the Ear, Nose, and Throat.—In the treatment of Otorrhea a solution of from 1-10,000 to 1-3000 is held in high esteem. Late writers (Schwartze, Laplace, and C. Behrens) employ tartaric acid to lessen the coagulating of tissue, in the following formula: B. Hydrar- gyri bichlor., gr. ss (0.032 grammes); acidi tartarici, grains xx (1.29 grammes) ; aquae, ounces iv (124.4 grammes). One-tenth of one percent, to one per cent, solution according to J. Gottstein (^Archives of Otology, vol. xiii, 1884) is sufficient to sterilize the ear. In place of instillation, W. Kirchner {Monatschr. /. Ohrenheilkunde, August, 1885, 229) saturates a delicate cotton string or cord about two millimetres in thickness in a weak solution of corrosive sublimate. Remembering the powerfully toxic charac- ter of the preparation care should be exercised in the use of corrosive sublimate in the middle ear, no matter what strength is used. The recognition of the bacillar nature of Auditory Furuncle renders the advice to saturate the wound made after incision with a lotion of bichlo- ride of mercury (1-10,000, 1-3000) fruitful of good results. Acute Eczema of the auditory passage is treated by Miot and Baratoux (^Rev.
