Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society; to the Controller of the London Telephone Service Encloses a cheque for £5.10.0 in response to the Controller's 'final notice' demands. Notes that, in light of the Society's telephonic communication with various departments of Government concerned in the prosecution of the War, and the fact that the Society has been a telephonic subscriber since the Telephones were first taken over by the Postmaster General, the Controller's threatening notices seem ill-timed. 30 March 1917
