Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to Henry Curtis, 2 Whitehall Court, SW 'In answer to your enquiry for information concerning "Thomas Curtis FRS", in the course of the XVII century, - I beg to inform you that there would appear to be some error. There never was a Thomas Curtis FRS. In fact there is no Curtis at all on our lists, from the foundation.' 23 December 1914
