Copy letter from Herbert Rix, to Dr Charles Scott Sherrington, Fellow of the Royal Society 'Dear Sir, We are not quite clear whether you wish all four of the micro-photos which you handed in yesterday to be reproduced. Prof. Schafer's [Professor Edward Albert] plates were done by the Autotype Co, and I propose to get yours done by the same. Yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 16 December 1893
