Copy letter from Robert William Frederick Harrison, to Mrs E W Miller, Alexandria Bay, Thousand Islands, New York, United States of America 'With reference to your letter of February 15, 1897, we have no copy of "Parentalia" in our Library, and it would, I fear, be somewhat difficult and costly to obtain. You will, no doubt, be able to find it in one [of] the great libraries of New York. I am, Yours faithfully, Robt Harrison Asst. Sec. & Library. R. S. [Assistant Secretary and Librarian, Royal Society]'. 1 March 1897
