HC Deb 07 August 1940 vol 364 c221W
Captain Graham

asked the Home Secretary how many times since 5th June last, sittings of the Camouflage Committee have taken place; how many biologists are on the staff of the Civil Defence Camouflage Establishment; and whether he is aware that any camouflage not based on the specialised advice of biologists and which ignores Thayer's principle is unable to provide maximum efficiency?

Sir J. Anderson

There has been one meeting of the Camouflage Committee since 5th June last. There is one biologist on the staff of the Civil Defence Camouflage Establishment. As to Thayer's principle, I would refer the hon. and gallant Member to the reply which I gave on 2nd May last to a Question by the hon. Member for the Scottish Universities (Sir J. Graham Kerr).
