In 1914, under the stimulus of the ability to examine postmortem material in a large percentage of fatal cases at the Infants' Hospital, we began a detailed study of tuberculosis in the first two years of life. This study while, perhaps, not disclosing anything very startlingly new, has given results which may be of value in emphasizing certain peculiarities of the disease at this period of life, and which have the advantage of being based on a series of necropsies on children under 2 years of age which is larger than any we have been able to find in the literature, at least in American literature. The conclusions presented in this paper are based on a series of 374 cases in which a clinical diagnosis of tuberculosis was made in the wards of the Infants' Hospital, and on a series of 138 necropsies in which lesions of tuberculosis were found.
