Ulcers: Nitric Acid, 119, a powerful escharotic, used to destroy unhealthy tissues and change the character of the surface. Potassa Chlorate, 225, in powder, applied to the surface, is remarkably beneficial in cases of unhealthy ulceration, in epithelioma, etc. Alum, 337, dried, is a feeble escharotic, and destroys unhealthy granulations. Zinc Sulphate, 319, dried, is a valuable caustic, and easily managed ; the chloride of zinc is more powerful and penetrating, as well as more painful. Pyrogallic Acid, 348. Potassa Fusa, 225, or the milder "Vienna paste, diffuses widely and destroys deeply. Silver Nitrate, 303, acts superficially, and is therefore to be used only when the mildest effects are necessary. Copper Sulphate, 309, is, like silver nitrate, a good application to change the character of an indolent ulcer, and to form a thin coating under which healing may proceed. Iodoform, 264, 271, in powder, dusted over the ulcer, is a capital dressing for syphilitic ulcers, irritable sores, and superficial ulcers generally; its odor for these purposes may be covered by thymol, menthol, or euca-lyptol. Carbolic Acid, 382, Salicylic Acid, 400, Boric Acid, 420, Resorcin, 404, Thymol, 428, Chlorine, 369, and Dermatol, 164, are antiseptic, deodorant, and alterative applications, of great value in wounds, unhealthy ulceration, and sloughing phagedena.

Morphine, 640, hypodermatically, in full doses, is of remarkable value in uremic convulsions.

Uric-Acid Diathesis: Aliment, 63, the acid fruits and starchy foods are proper, but meats and other nitrogenous materials objectionable. When excess of uric acid is due to deficient oxidation, Nitric Acid, 119, especially is of the greatest value; also muriatic and lactic acids. Alkalies, 219, the potash salts, particularly after meals; also the Alkaline Waters, 229. Air, 98, Massage, 102.

Urine, Incontinence of: Belladonna, 530, the most important remedy, and the alkaloid Atropine is the best preparation, a quantity sufficient to induce its physiological effects being necessary. Ergot, 501, is effective when there is a paralytic sphincter, and in the case of diseased prostate.

Uterus, Fibromata of: Ergotin, 501, subcutaneously and by stomach and rectum. Hydrastinine. 191, of special value in myomata and haemorrhage. Gold and Sodium Chloride, 297, persistently used. Calcium Chloride, 223, also taken for a long time. Saline and alterative Waters, 253 et seq. ; those of St. Catharine's, Canada, of Homburg and Kreutz-nach, etc. Iodine and Iodoform, 260, tincture and glycerites, 263, applied topically.

Hydrastinine, 191. is of value in uterine haemorrhage and congestion. Electricity, 470, galvanism— an interrupted current, of great value in cases of simple enlargement. Iodoform, 263, and Iodo-Tannin, applied directly to the uterus, promote absorption. Gold and Sodium Chloride, 297, long continued in small doses, does much good. Phytolacca, 725, Digitalis, 509, and Cimicifuga, 522, are very useful in sub-involution. Ipecacuanha, 742, has remarkably good effects in recent cases of sub-involution, with menor-rhagia or metrorrhagia.
