Letter from Edward Cadogan, 8 Gloucester Square, Hyde Park, to [Francis Alexander] Towle, Assistant Secretary of the Royal Society 'Dear Sir, I am exceedingly grateful to you for your most kind and courteous reply. Acting upon your suggestion, I have written to Capt. C. Kinght asking him if he will help me to procure the lecturer of the sort I indicated in my last letter. I must apologise to you again for troubling you in this manner and I cannot thank you sufficiently for the assistance you have rendered to me. Yrs. sincerely, Edward Cadogan'. 24 November 1921
