a tropical disease, prevalent in India, China, Java, and the West Indies. It is described by Sir Patrick Manson as characterized by a peculiar, inflamed, superficially ulcerated, exceedingly sensitive condition of the mucous membrane of the tongue and mouth; great wasting and anaemia; and more or less diarrhoea, with pale and frothy fermenting stools. It is an obscure disorder, and the treatment recommended is rest and milk diet.
