Copy letter from Robert William Frederick Harrison to Sir Ray Lankester, KCB, FRS 'The difficulty about sending you at once pulls of your paper is that Ede & Townsend have not yet delivered their plate. We have worried them and so have the printers, but Harrisons just report per telephone that the plate is still undelivered. However I think you should be able to get copies by end of the week. The paper should be out by that and I will ask Harrisons to send you by post 2 or 3 early pulls of your private copies.' 22 April 1912
