The mere fact of iny having written these papers has put me 

 into communication with fellow lovers of nature, and has given me 

 access to standard worlds, so that 1 have been able to correctly identify 

 most of the species mentioned. I am deeply indebted to jMr. J. D. 

 de La Touche, C.jM.Z.S., M.B.O.II., who very kindly allowed me to 

 go over his wtjnderful culleetion of Chinese Birds, than which none 

 more complete exist, except that in the British ]\Iuseum. I am also 

 indebted to iMr. OldHdd Thomas, F.ll.R., F-Z.S., of the British 

 ]\Iuseum, and to Dr. Gerrit S. JMiller, of the Smithsonian Institution, 

 for assistance in the identification of many new mammals of North 

 China, while Br. iMorrison, by allowing me access to his magnificent 

 library, enabled me to further identify and verify the names of many 

 of the old ones. The following gentlemen very kindly supplied me 

 with photogmj.hs, witliout wliicli the illustrati(jns would have been 

 far from complete— Br. I>. H. Atwood, Mr. iMalcolrn, P. Anderson, 

 Captain T. Holcomb and Wr. W. A. Mace. To all these kind friends 

 I wish to convey my heartiest thanks.
