Copy letter from Robert William Frederick Harrison, to Percy F Nursey, Secretary, Society of Engineers 'Dear Sir, In reply to your letter of the 29th February, the Secretaries feel that such a selection as you desire them to make from among the names of the Fellows of the Society would be too invidious a task for them to undertake, and they have no information as to the fees which it is usual to pay for Lectures such as you have in view. I am, Dear Sir, faithfully yours, Robt [Robert] Harrison Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 3 March 1904
