Copy letter from Robert William Frederick Harrison to W R Cooper, 82 Victoria Street, SW 'My dear Sir, Proceedings, Royal Society. I have to acknowledge the receipt of cheques and orders from 31 members of the Physical Society, each of one guinea amounting in all to £32. 11s. 0d. You mention Col. Malcolm as desiring to discontinue his subscription, but Col. Malcolm paid his subscription on January 1st direct to our bankers, Messrs Robarts, Lubbock & Co., as in the previous year. Perhaps you will be good enough to bring this to his notice, if you think it necessary.' 19 February 1909
