Copy letter from Robert William Frederick Harrison, to Dr Gilbert Thomas Walker, Fellow of the Royal Society In reply to Walker's letter of 22 May, all back volumes of the 'Philosophical Transactions [of the Royal Society]' preceding that last five years of publication may be purchased by Fellows at one-third of the published price. On the cover of each issue of the 'Philosphical Transactions' is a list of the separate Papers recently published, and Messrs Dulau & Company have a list of those papers published between 1800 and 1895 and possibly at even a later date. Is writing today to have one of these lists sent to Walker. 22 June 1905
