Copy letter from Robert William Frederick Harrison, to Messrs Wesley & Son, 28 Essex Street, Strand, W.C. In reply to the Messrs letter of 22 July, the Society regret they cannot supply any of the separate numbers of the 'Philosophical Transactions [of the Royal Society]' that the Messrs mention as they are all out of print. They might possibly be able to obtain some of the numbers from Messrs Friedlander & Sohn, 11 Karlstrasse, Berlin. The only other way to obtain the papers that the Messrs want would be to purchase the volumes in which they appear. 23 July 1907
