Some time ago1 we called attention to the class of cases whose symptoms, although they clinically resemble typhoid, are caused by a group of organisms standing between the typical colon and typhoid bacilli in cultural characteristics. This group of organisms shows among its individual members slight cultural differences, no greater than those between various strains of colon bacilli. Because of its intermediate position the organism has been variously designated as the "paracolon" or the "paratyphoid" bacillus. The results of the infection have also been various, the organism having been found sometimes in local abscesses, sometimes with pyemic manifestations, and often with a clinical picture very similar to that of typhoid fever. Therefore, it would seem justifiable to make a distinction on clinical grounds and to separate cases that resemble typhoid from those that do not, even if the infection is by similar organisms, the first class of cases being
