1905. In Impetigo, The Internal Use Of Nitric Acid (F3ss

in Oj. of a bland fluid) is strongly advised by Rayer. "It seldom happens," he adds, "that this medicine is continued for a month or six weeks without accomplishing a cure." In Lepra, a similar mode of treatment is very favourably mentioned by Mr. E. Wilson. §

1906. In Alopecia, a serviceable liniment is made by adding, to a certain q aantity of Olive Oil, as much Nitric Acid as will make it pungent, but not acrid.

1907. In Porrigo, Scabies, and some obstinate Skin Diseases, the liniment advised in the last section may be used with advantage.

1908. In Caries, and in non-syphiiitic Ulcers of the Legs, when the latter are attended with a thin ichorous discharge, Dr. A. T. Thompson || states that he has derived great benefit from a wash composed of f3ij. of the diluted acid and Oj. of water.

1909. Other Diseases

In Hooping Cough, Nitric Acid is strongly advocated by Dr. Gibb. The following is one of his formulae: - ℞ Acid. Nit. Dil. (Ph. L.) f3xij., Tinct. Card. Co. f3iij., Syrup, fiiiss., AquAe fj., M. Dose, a dessert-spoonful every one or two hours. Other observers have also borne testimony to its value in Hooping Cough. In Intermittents, Dr. Hammond** corroborates the statements of Drs. Bailey and Mendenhall as to the anti-periodic powers of Nitric Acid in doses of gutt. x. properly diluted with water thrice daily. Warts are easily removed by cutting off the top, and touching them daily with Nitric Acid, and removing from time to time the stratum of disorganized and hardened epiderma with the knife. (E. Wilson.*) In Mol-luscum, M. Emery employs Nitric Acid as a caustic.
