Copy letter from Herbert Rix, to Mr R Richards, Willis's Rooms 'Sir - I have not any doubt that the origin of the difference in our number is that Mr Jackson, who was expected up to the last moment, did not arrive. You did not send the corrected account in the envelope with your note. Please forward it. Yours truly, H Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 11 December 1888
