Copy letter from unknown correspondent; to G.E Mainwaring Esq., London Library, St. James Square, S.W. Dear Sir, In answer to your enquiry concerning the entry in Sir Arthur Church's Catalouge of a paper by sir Henry Mainwaring, I beg to say that the title as entered is, "Some Extracts from the Seamans Dictionary" of Sir Henry Mainwaring. - 12pp. The extracts are manuscript and unprinted, so far as the Royal Society was concerned, but probably appeared in the later editions of the "Dictionay", as published. I trust this information may be of service to you and remain.' [17 March 1916]
