From July 1, 1908, until April 1, 1914, a period of almost six years, 1,320 autopsies were performed at the Babies' Hospital of the City of New York. Of these subjects 178 showed tuberculous lesions, or 13.5 per cent, of the total number, a proportion slightly lower than Lubarsch1 found among 747 children up to the age of 5 years. Lubarsch's examinations extended over a period of five and one-half years, and he found 128 cases of tuberculosis, or 17 per cent. A study2 of the earlier Babies' Hospital cases showed 16.4 per cent. tuberculous cases among 1,131 autopsies. The contrast with adult percentages is very striking, whether we accept Lubarsch's figures, 69.2 per cent., or those of Naegeli,3 93.1 per cent. as the average.
In age the cases included in our study varied from 2½ months to 5 years, as follows:
