Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society; to Messrs. Taylor & Francis Requests one double subscription invoice always to be sent by the New Year for 'Annals and Phil. Mag.' as the subscription for the latter was overlooked. There is handwritten note saying he is still unable to trace the August Phil. Mag, and asks if they are willing to supply it, and they will return a copy if it turns up later. 14 October 1919
