Note 352 — PHARMACOLOGIA.

Nitric acid may be considered as one of the most efficient agents in our possession for exciting prompt vesication. For this purpose, we believe it was first used in the epidemic Cholera of the East Indies, and the success which attended it in that fatal disorder suggested its application in a variety of other diseases. The mode of using it is to rub the surface intended to be vesicated, with the pure acid, and as soon as pain is produced, to neutralize the acid by washing the part with a solution of salt of tartar. If the object is to continue the irritation, a common blister may be laid upon the part. Ed.
