Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society to Captain W H Rowthorn, 168 Upperthorpe, Sheffield 'In answer to your letter of the 3rd instant, concerning the copy of Grew's Museum Regalis Societatis, I beg to inform you that the Society already possess several copies of this work. We are therefore not prepared to acquire yet another. I thank you for your letter and might perhaps suggest (should you desire to sell your copy) that you communicate with a good bookseller, as the work has market value, especially if in good condition.' 4 February 1915
