Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to Sir Alexander Pedler FRS 'With reference to the non-delivery to you of the Proceedings of the Society, it would seem that your name has not been on Messrs Harrison & Sons's postal list for about four years. Have you any recollection of stopping the issue of Proceedings? Kindly say whether you wish to be put on the printers' list again, and whether for both series or only one.' 9 June 1915
