Copy letter from Robert William Frederick Harrison, to Mrs Edmond Hills, 1, Devonshire Place, Portland Place, W. 'Dear Madam, Your application for the transference of Major Hills' Soiree invitation to Mr L. S.

Believe me, faithfully yours, Robt [Robert] Harrison Asst. [Assistant] Secretary R.S. [Royal Society]'. 14 June 1907
