A d:; occurring chiefly in India, and characterized by the formation on the foot (sometimes on the hand) of a tender purplish swelling, which in time suppurates, the pus being evacuated through one or more sinuses. These sinuses discharge a seropurulent liquid containing peculiar bodies resembling gunpowder-grains or fish-roe. The disease is chronic, but remains local, and is believed to be due to an organism allied to the actinomyces-fungus. It is also termed Mycetoma. Magendie’s Solution. See Morphin.
