The disease had occurred in a patient from China, and he had directed attention to this variety of infection in the British Journal of Dermatology in 1906.

Fleet-Surgeon Collingwood said that he had seen cases of dhobie itch on the China station. The men were supplied with linen bathing-drawers, which were washed on board, apart from the ordinary washing, and there were no more infections. For treatment, ship's yellow soap, made into a creamy paste, had been used, and it was apparently very effectual, although in some cases he was afraid it had removed the skin as well as the parasite.

Mr. Cantlie said that there was a somewhat similar disease prevalent on the coast of China, which was commonly known as foot tetter. It commenced by the formation of a bleb on the sole of the foot; the bleb ultimately broke, and, by and by, hard, bare, shelly flakes of skin formed and extended all over the sole and between the toes.
