Copy letter from Herbert Rix, to Professor Michael Foster, Secretary, Royal Society 'Dear Sir, Mr Mallock writes that he fully agrees to your suggestions about his paper. In Cajal's postcard which you enclose I see he speaks of sending the original of the lecture "10 days before March 1st". Your last instruction to me was that the Croonian Lecture was to be on March 8th. I suppose there is no misunderstanding about this? I am yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 5 February 1894
