Remarks - The power possessed by acetic acid of slowly dissolving epithelial tissues when kept in prolonged contact with then is frequently utilized for the destruction of horny excrescences of all kinds. For this purpose the pure glacial, rather than the weaker officinal acid, should be employed; and if dilution should be desired, this may often be advantageously effected with a menstruum, composed in part of glycerine. I have found equal parts of glacial acid and glycerine of service in the smaller patches of erythematous lupus. Acetic acid differs in its action very materially from the other so-called caustic acids and caustics generally. On horny growths it exerts a solvent action, without the production of a distinct slough or eschar, while in lupus it appears to stimulate absorption of the morbid deposit. The direct injection of acetic acid into the substance of morbid and more especially malignant growths, has not proved so serviceable as it was at first supposed would be the case. The tumor might be destroyed orgreatly lessened, but secondary developments of the disease, it is asserted, appear more frequently than when other methods of eradication have been employed.

The officinal preparations are: Acidum Aceticum, and Acidum Ace-tieum Dilutum.
