Yet among normal men in one of these organizations the incidence of hemolytic streptococci was 26 per cent and in the other, 16.7 per cent. In both organizations the incidence among normal individuals compares closely with that of the patients after a period in the measles wards of the hospital. =Discussion.=—Three features of the data collected at Camp Funston are noteworthy. First, the small percentage of S. hemolyticus carriers among the men admitted to the hospital with measles as compared with the percentage found in normal men in the camp. Second, the increase in the number of S. hemolyticus carriers among patients during their stay in the hospital, the increase continuing until it approaches that of the normal men on the outside. Third, the prevalence of hemolytic streptococci in normal throats. In comparing men arriving at the hospital acutely ill with measles with normal men in the organization from which they came, only one variable can be found on which to base the differences observed in the two groups. This is the advent of the acute disease. The figures seem to suggest a temporary disappearance of hemolytic streptococci from the throats of patients acutely ill with measles, at least, to such an extent that the same cultural methods fail to identify the organisms.
