Copy letter from Messrs W B Keen & Company, 3 Church Street, Old Jewry 'Dear Sirs, The Treasurer writes me this morning: "If I can manage it I will call at Burlington House on Monday". I am afraid this is not of much use to you as he does not mention the hour, but he generally comes between one and four. Yours faithfully, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 5 October 1889
