Corn Plasters

Prep. 1. From white diachylon, 3 parts; yellow resin, 2 parts; verdigris, 1 part; melted together, and spread on leather. 2. From galbanum plaster, 1 oz.; verdigris, 1 dr.; as the last. 3. From resin plaster, 2 oz.; black pitch, 1 oz.; verdigris and sal-ammoniac, of each 1 ⁄ 2 dr. 4. To the last add powdered opium, 1 dr. Recommended to allay pain, . 5. (W. Cooley.) A piece of spread adhesive plaster is placed upon a table, and a piece of card paper having a round hole cut in it the size of the central portion of the corn is laid upon it; the exposed part is then softened by holding a piece of heated iron for a second or two near it; the card paper is then instantly removed, and nitrate of silver, in fine powder is sprinkled over the part which has been warmed. As soon as the whole is cold, the loose powder is shaken off, and the plaster is ready for use. Very cleanly and convenient. Two or three applications seldom fail to effect a cure. 6. ( Mechanical Corn Plasters. ) From common adhesive plaster spread on buckskin, amadou, or vulcanised india rubber, cut into pieces, and a circular hole corresponding to the size of the corn punched in each.
