To the Editor: —
Dr. Ustvedt's statement (The Journal, March 9, p. 851) that "tuberculin negative individuals who are not exposed to infection cannot be expected to develop clinical tuberculosis" has been the crux of our argument, which Dr. Harrington and I have emphasized in numerous publications for fifteen years. Therefore his statement that "this is a fact that has been neglected by many investigators and latest by Myers and Harrington" is hardly justified. On this point, we are in complete agreement with Ustvedt. One of the objects of our paper (The Journal, Nov. 17, 1934, p. 1530) was to emphasize the fact that children who react negatively to the tuberculin test, when observed over a period of years and into adult life, are much better risks from the standpoint of the development of clinical tuberculosis than children who at the same time have positive tuberculin reactions. To be sure,
