    carded. If a diluted oleate is required for application it may be ordered in the same manner that all dilutions are prescribed—so much of the oleate and so much of the diluent. It is not my purpose to present in detail the chemistry and phar¬ macy of each particular oleate, as the foregoing remarks, with the subjoined table, showing the percentage of base in each salt, will give an insight into their mode of manufacture and composition: Aluminium oleate contains 3.1 % metallic aluminium equivalent to 17.9 % aluminium hydrate. Arsenic oleate a 8.16 % metallic arsenic ii 21.5 % arsenious acid. Bismuth oleate a 19.9 % metallic bismuth ft 44.3 °/0 bismuthyl oxide. Copper oleate is 10.1 °/0 metallic copper a 12.8 c/0 cupric oxide. Iron oleate a 9.04 a/0 metallic iron a 11.5 a/o ferrous oxide. Lead oleate a 26.7 °/o metallic lead a 29.2 % plumbous oxide. Mercury oleate a 26.2 °/o metallic mercury a 28.35% mercuric oxide. Quinia oleate a 57-2 c/o quinia. Silver oleate a 27.6 °/c metallic silver a 59.3 % silver oxide. Zinc oleate k 10.4 °/o metallic zinc a 12.9 °/0 zinc oxide. Oleate of Aluminium —In color, light yellow, of plastic consist¬ ence, and somewhat adhesive. For application, it should be melted with an equal part of a fatty base, such as lard or cosmoline. It pos¬ sesses an astringent action, as well as being somewhat stimulating. It may be prescribed in all skin diseases in which there is much discharge, such as dermatitis, pustular eczema, etc. In the treatment of simple ulcers an ointment of this oleate is frequently productive of improve¬ ment. In pustular eczema of children, it is useful, checking the dis¬ charge and exerting an alterative action on the diseased skin. An excellent ointment for such cases is the following: R. Hydrargyri chlorid. mit., gr. xx. Aluminii oleatis, Petrolati, aa 5 ss. Ft. ugt. Oleate of Arsenic.—In color, reddish-yellow, solid and granular, melting over a water-bath; insoluble in alcohol, but soluble in petro¬ leum benzin, a filtered solution of which, if treated with hydrogen sulphide, will give a yellow precipitate of sulphide of arsenic. It should be melted with from two to six parts of a fatty base for dermic application. In epithelioma and the ulcerations of lupus, it may be found useful. It is, however, in these diseases, inferior to other well- known methods of treatment. In a few cases of psoriasis, its appli-
