3. (Wholesale.) From metallic arsenic, 61 gr.; iodine, 500 gr.; mercury, 154 gr.; rectified spirit, 112 fl. oz.; distilled water, 2 quarts; hydriodic acid, 5 fl. dr.; as No. 1; the product being made up with distilled water so as to measure exactly 4 pints, or 80 fl. oz., or to weigh 5 lbs. 114 oz. (av.), when cold.

Obs. Great care must be taken that the whole of the arsenic be dissolved, which can only be effected by the most careful trituration. Soubeiran recommends the employment of 1 part, each, of the respective iodides, with 98 parts of water, as furnishing a simpler and equally effective product, proportions which are almost exactly those employed by Mr Donovan.—Dose, 10 to 30 drops, twice or thrice a day, preferable soon after a meal; in lepra, psoriasis, lupus, and several other scaly skin diseases. It is a most valuable medicine in these affections.
