Copy letter from Robert William Frederick Harrison to Messrs John Dickinson & Co, 65 Old Bailey, EC 'Dear Sirs, In 1907 your firm kindly took from us at an agreed price a consignment of sheets of printed matter, representing surplus Royal Society publications. Recently, there has been a further overhaul of stock of this kind, and it is now desired to clear a batch of sheets of "Proceedings [of the Royal Society]" and other matter from the basement, approximately 4 tone in weight. I should be glad to hear whether you could take over this supplementary batch, which is all of good quality. We should be please to show the above material, at any convenient time.' 15 March 1910
