Copy letter from an unknown correspondent, to Mr D Nutt, 270 Strand 'Dear Sir - In answer to your memo [memorandum] of July 10, our books should indicate the arrival of any work for the library, & are strictly kept. We find no entry for the 2 parts of Bibliotheca Mathematica, which you say you supplied, & we think they must have been misdelivered. But as the matter is a small one we shall be glad if you will now obtain for us Bibliotheca Mathematica. 1892. Nos 3 + 4'. 20 September 1893
