Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to [Frank Edward] Smith Esq., CB, FRS 'I have just received the enclosed letter from Mr. Moullin suggesting an exhibit for the May Soiree. You will perhaps remember that we asked him to exhibit last year and a paper of his was subsequently published in the Proceedings. Do you think that we should accept his offer?' 23 April 1929
