Eighty-odd cases of vaccinia of the eyelids have been recorded in the literature. Of these, however, only about 25 per cent, were due to vaccinated persons inoculating their own eyes, the remainder being due to vaccinators, mothers, nurse-girls and others infecting their eyes from the vaccination vesicle of some one under their care. It is on account of the infrequency of the cases brought about by homo-inoculation that we report the one described herewith.
Incidentally, we wish to call attention to several associated facts. In addition to the cases mentioned above, eight instances have been reported in which the cornea was accidentally the primary seat of inoculation. In eighty-odd cases of palpebral vaccinia, the cornea was involved by extension in only about 10 per cent. Several cases of a primary "vaccinal conjunctivitis" have been reported, but it is difficult to gain from the literature a clear idea as to the
