The patient was last seen in the first week of February, 1894. The lesions seen on December 13th disappeared soon afterward, leaving the customary pits, but a few weeks ago there had been another mild outbreak which was still to be seen. A few small, primary vesicular lesions without central discoloration were present, one of which was excised for microscopical study. The patient had been using by advice an ointment colored black by lampblack, but this appears to have had no influence on the recurrence of the lesions. It was impossible, however, to determine how faithfully this procedure had been carried out. The disfigurement of the application made it naturally unpopular.
