Copy letter from Herbert Rix, to Dr Sherrington, Fellow of the Royal Society 'Dear Sir, You know, I believe, that Cajal's paper is now voted for "Proceedings" ['Proceedings of the Royal Society'], and, of course, I should like to get on with it. Nothing can be done till I get the photographs from you which are to be reproduced. I suppose you will send them shortly? Yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 22 March 1894
