Copy letter from Robert William Frederick Harrison to Professor G [George] E [Ellery] Hale, For.Mem.RS 'I much regret that owing to pressure of work I jave overlooked your letter of October 14st last. I am now able to send you a second copy of the Anniversary Programme in which I have inserted the names of all the Universities, Institutions etc, to whom an investigation to the 250th Anniversary was originally sent. Trusting that this will meet your requirements. I suppose you have heard that Sir J Larmor have now given place to Prof Schuster as Physical Secretary.' 18 December 1912
