Dr. GRAHAM LITTLE showed (1) a case of _Tinea cruris_ in a private patient, a Japanese gentleman, an exponent of the art of ju-jitsu. The patient had noticed the eruption for about a month and a half, but could not be certain that he had not the first trace of it before he left Japan, six months ago. He was engaged in teaching the national form of wrestling, and in his exercises had to strip almost entirely, so that he might well have contracted the disease from a pupil. There were now large patches of scaly dermatitis occupying the perineum and groins with extensions on to the scrotum. On the left side of the cheek there was a circinate patch the size of a florin, having a somewhat intricate whorled pattern, suggesting tropical ringworm. On the outer side of the ankle just below the external malleolus there was a small patch the size of a sixpence, which was fading. No treatment had been applied to any of the lesions. There was no history of infection among his pupils, with the exception of one, a friend, who stated that he had some patches on his skin which he noticed while on the voyage from Japan. The patch on the groin was scraped, and in the scales thus obtained a very large-spored mycelium with unusually long branches was demonstrated. (2) A case of _Pityriasis rosea_ in a girl aged about 12 years, with very characteristic pale pink patches, in size about one quarter by half an inch, appearing first upon the upper part of the trunk above the clavicles, and arranged in lines directed obliquely from the summit of the shoulder to the clavicle. Upon the back in the intervertebral groove there were numerous similar patches and also smaller papules, round and faintly scaly. The eruption had made its appearance two days previously, and it was not now present upon the limbs or lower upon the body than the groin. It itched slightly. There was no similar eruption in any member of the family. This was the second case the exhibitor had seen of the disease this week, and it was probably true that the malady was an exanthem occurring in epidemic form during certain periods of the year. Dr. WILFRID WARDE agreed as to the epidemic character of the disease, and he remarked upon the general good health of the patients. He thought that the so-called “herald-patch” was frequently missed, both by the patient and the physician.
