    COLOUR VISION SCREENING. The inclusion of colour vision testing in the school medical inspection, was introduced in the Christmas term of 1960, so that school leavers of Secondary Modern and Grammar Schools were screened. In view of the small number of girls who possess a colour vision defect, boys only were thus examined.

DEFECTIVE HEARING. Plans directed towards the ascertainment of defective hear- ing in school and pre-school children, were adopted in 1960-1961. Two School Medical Officers and two health visitor/school nurses in turn, had undergone the courses at the Department of Education of the Deaf at Manchester University, and equipment considered essential for screening purposes was purchased, including an Amphiox Pure-tone Audiometer, Model 70. A soundproof clinic was completed during 1960. In addition, it should be pointed out that we enjoy the full co-operation of our E.N.T. Surgeon. In the Christmas term 1960, a small Pilot Audiametric Survey of school-entrants was decided on and carried out at three schools, in which 67 children were tested. These schools were
