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]'.
