Copy of letter from J D Griffith Davies, Assistant Secretary to the Royal Society to Sir William Bragg PRS ' I have written to Dr Myers and suggested he should ask Sir Stephen Gaselee how he ought to proceed in the matter of his visit to America. As you know Sir Stephen is always most helpful in such matters. I return Dr Myers letter to you: those which he enclosed in his letter to you I have returned to him. ' 3 April 1940
