In 1,036 children Heaf testing was carried out and the result related to age, nutritional status and the presence or absence of previous B.C.O. vac cination. The observed pattern of tuberculin sensitivity is descriptionbed, compared with the reports of previous investigations and discussed in the light of factors known to promote and depress tuberculin sensitivity. The Heaf test when recorded by grade of reaction and related to those factors known to induce or diminish tuberculin sensitivity remains a valuable diagnostic investigation both in children who have received B.C.G. vaccine and in the unvaccinated.
