Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to the Librarian, the University, Aberdeen 'Referring to your letter of March 3, your cheque for £17, subscription to the International Catalogue, 13th issue, was duly received and was sent on to Dr H F Morley, the Director of the Catalogue. I am sorry that an official receipt (now enclosed) was not sent to you from here. It seems to have been overlooked, and I hasten to rectify the omission. It would, perhaps be more convenient if in future, you sent the subscription direct to Dr H F Morley, International Catalogue of Scientific Literature, 34 & 35 Southampton Street, Strand, London, WC.' 11 March 1915
