Abstract
THE Board of Trade has published the annual return of the sight tests used in the mercantile marine for the year ending December 31, 1910 (Parliamentary Paper, Cd. 5876), a return which includes the examinations in both form and colour vision. In the course of the year 7502 candidates were examined, including fishermen who sought to obtain certificates as skipper or second hand of fishing boats, and of this total 109 (1.46 per cent.) failed in form vision, and one of them, who was re-examined, failed again. One hundred and forty-one failed in colour vision, but of these 69 were re-examined on appeal, and 29 of them passed, leaving 112 (1.56 per cent.) as ultimate failures.
