During the past two years it has become increasingly apparent that the virus of poliomyelitis may be readily isolated from stools of patients with poliomyelitis. Many reports1 now testify to the ease with which this may be accomplished, not only from the stools of patients with the paralytic type2 but also from those of patients with the common abortive type.3 In fact the stool method has quickly found its place in the study of this disease, and during this short period of time our knowledge of human carriers has been considerably enhanced. Already Lépine4 in Paris has followed one child convalescent from abortive poliomyelitis who harbored the virus in the intestinal tract as long as one hundred and twenty-five days, and Kramer and his co-workers,5 more recently in Detroit, have given a convincing report of "healthy intestinal carriers" in this disease. These observations point the
