§ Dr. Strossasked the Minister of Health what proportion of children leaving school are tuberculin negative; and how far the figure has shown significant change in the past few years.
§ Mr. Iain MacleodI regret that information is not available in this form; but a survey conducted by a committee124W of the Medical Research Council in 1949–50 in 22 selected areas on a sample basis showed that 56.1 per cent., over all, of children aged 14 and 48.5 per cent. of those aged 15–16 were tuberculin negative, and there is some evidence that these percentages are increasing.
