41. Mr. CATHCART WASON
asked the President of the Board of Trade whether his advisers on colour blindness only consist of those who have advocated the wool test; and, if so, now that this test has been shown to be so defective, whether he will consider the advisability of adding to his advisers someone with knowledge and experience of the lantern test?
My right hon. Friend has no reason whatever to think that his advisers have not the knowledge and experience necessary to enable them to advise on the lantern test which has been adopted on the recommendation of the recent Sight Tests Committee, of which two of them were members.
