Itmay even invade the perineum, anus, thigh, and mons veneris, and, like noma ofthe mouth, seems to have a tendency to penetrate deeply and attack the bone. Noma may be attended with high fever, chills, and great prostration, but thespecial symptoms are not infrequently masked by those of the previously exist-ing disease. The condition is exceedingly fatal, and the patient usually sinksinto a state of profound prostration and rapidly succumbs.

A bacillus, resembling that of diphtheria, has been de-scribed by Bishop and Ryan and by Schimmelbusch, but is not invariably and Zambilovici have isolated from some cases a pathogenic micro-organism capable of inducing gan-grene when injected into and Lingard have also de-scribed a germ which the} believeto be specific.
