358 Report of the Committee on Colour- Vision. 



"(Modified after the Regulations issued from the Horse Guards, 

 by Prof. Longmore, in 1868.) 



" Each test dot on this card is one-fifth of an inch square, and 

 corresponds, at a distance of 15 feet, with the bull's-eye, 2 feet 

 square, at 600 yards, required by order to be distinctly seen by 

 every acceptable recruit. 



" Men. — With perfectly acute vision these test dots ought to 

 be clearly visible in full- daylight at 19 yards. 



"1. Expose the card in full daylight at a distance of 15 feet 

 from the candidate. 



" 2. Examine each eye separately, taking care that the unused 

 eye be merely covered, not pressed upon or closed. 



" 3. Vary the number and position of the dots by covering 

 some of them and moving the card. 



" 4. Test each eye as to recognition of colour."

" Sir, — In reply to your letter of the 20th instant, I am 

 directed by the Civil Service Commissioners to inform you that 

 in the medical examinations conducted by them no tests of Colour 

 Vision are employed, except in the case of the examination for 

 the India Civil Service, where the tests used are of the simplest 

 character.
