Mr. Milton advises Tartar Emetic to be given in grain doses every second hour, until a marked effect is produced upon the inflammatory swelling. He states that this treatment is very efficacious, and supersedes, in the majority of instances, the necessity of surgical interference. To Navus, Dr. Zeissl§ recommends the application of a plaster containing gr. xvj. - xviij. of Tartar Emetic, and 3j. of diachylon. A portion of this should be spread all over, and somewhat beyond the nAevus, and kept in situ by means of strips of gummed paper. In five or six days the nAevus begins to suppurate; a crust forms, which falls off in about fourteen days, leaving a surprisingly slight cicatrix. It is only applicable to nAevi of medium size.
