§ 60. Mr. LYNCHasked the President of the Board of Trade whether Dr. Edridge-Green was at any time requested by the Board of Trade to submit an efficient test for colour blindness; whether, as a result of considerable experimentation and original research, Dr. Edridge-Green devised that form of lantern which is now employed in the official tests in the Navy, and which, after slight modifications, was adopted by the Board of Trade; whether the Board offered to Dr. Edridge-Green 1175 any reward or acknowledgment of his services; and whether, in view of the importance of the material results which have followed from Dr. Edridge-Green's scientific researches, he will recommend him for a suitable reward?
§ Mr. PRETYMANDr. Edridge-Green was at no time requested by the Board of Trade to submit a test for colour blindness. The lantern adopted by the Board for testing colour vision was not devised by Dr. Edridge-Green, but was devised by a Departmental Committee appointed in 1910 to investigate the question of sight tests. As regards the remainder of the question, the answer is in the negative.
§ Mr. LYNCHWill the hon. Gentleman look into this question again personally, on the ground that the Board of Trade have simply taken Dr. Edridge-Green's invention and slightly altered it? Since the days of Thomas Young he is the only British man of science who has contributed valuable work in this particular field of research.
§ Mr. PRETYMANI have looked into the question this morning, and my information does not tally with the statement of the hon. Member; but I will look into the matter again.
§ Mr. PRETYMANI will look into the matter again.
