The present report is of moment only as it is, perhaps, the first report of a case of sporotrichosis in which simply the primary, or chancre, stage was manifested. It is of interest that the chancre was reproduced in a rat with recovery of the organism, and that a cultural pleomorphism was demonstrated following the single exchange of hosts.

The often vaunted ease with which one may demonstrate the presence of Sporotrichum was conspicuous by its absence. This might have been due to the strain of the fungus. Or possibly the observations of others were made on material obtained from secondary lesions. The necessity of making many cultures and inoculations in the presence of any intractable foreign lesion which may come to hand is adequately demonstrated, and we are of the opinion that any generalized statement regarding either ease of isolation or uniformity of results as applied to fungi should
