    Special Duty. Candidates for special duty under Government must possess such an amount of acuteness of vision as will, without hindrance, enable them to perform the work of their ofifi.ce for the period their appointment may last. In all cases of imperfection of colour sense a note will be made on the candidate's papers. HOME CIVIL SERVICE. There is no fixed standard. The candidate is referred to a competent medical adviser, leaving him to apply whatever tests he may deem suitable, and whatever standard the particular situation may require. A candidate is considered unfit if he has any serious defect in vision. A moderate degree of ordinary short sight corrected by glasses would not, as a rule, be regarded as a disqualification ; but candidates for the Customs Outdoor Service are liable to disqualification for any defect of vision. Candidates for some other appointments of a special character would be rejected for colour blindness, but for the Covenanted Civil Service of India and for ordinary home appointments it is not by itself a dis- qualification. PRISON SERVICE. Candidates are expected to have normal vision in both eyes, and any slight departure from normal vision is considered on its merits in accordance with the duties which the candidate would be required to perform if appointed. THE METROPOLITAN POLICE SERVICE. Candidates are required to have normal vision in both eyes, without glasses. The ordinary test-types are used, and the range of accommodation is sometimes, but not uniformly, tested. Candidates who show only slight deviation fiom the normal standard are considered on their merits. ENGLISH RAILWAYS. No uniform standard. Each company has its own standard. Every engine-driver should have normal colour perception: and, without glasses, vision should be at least x% in each eye.
