Letter from William Lawrence Bragg, on a paper 'Precipitation in the alloys of copper and silver' by Charles Sykes and W F Cox to J D Griffith Davies, Assistant Secretary of the Royal Society When he communicated the paper, it didn't occur to him that it might be of value to the enemy and he is 'not so confident' in guaranteeing that it isn't. The paper could be sent to Moore, who is the head of the Non-Ferrous Metals Research Association. If Moore thinks all is well, then he will regard himself as covered. If Egerton agrees, he asks that the paper be sent to Moore. [Not published]. 17 February 1940
