Copy letter from Robert William Frederick Harrison to W R Cooper, Physical Society of London, 32 Victoria Street 'My dear Sir, I am obliged to your for remitting Mr D Owen's cheque for one guinea, his subscription to the Proceedings [of the Royal Society] for 1908. Mr Owen is, I notice, a new subscriber, The reduced rate for Proceedings Vols. 76, 77 and 78 was a privilege offered to the original subscribers, but I am afraid it will not be possible for us to extend it to subscribers for 1908. The volumes in the A Series are on sale at Messrs Harrison & Sons, 45 St. Martin's Lane, WC, at the published price of 20/- each.' 24 March 1908
