Letter from Felix Semon, 39 Wimpole Street, Cavendish Square, London, to Robert [William Frederick] Harrison 'My dear Sir, I am very much obliged to you for your kind information in reply to the questions which I addressed to Professor [Joseph] Larmor. I beg you to accept my best thanks. It is particularly important for me to be able to give a reply to Professor Waldeyer, and I will do so at once. With regard to the participation of the deputation in the banquet, I shall expect to hear from Professor Larmor. Believe me, Yours very faithfully, Felix Semon'. 23 February 1905
