308 ANNALS NEW YORK ACADEMY OF SCIENCES 



EEPORT OF THE LIBEAEIAN 



It is doubtful if in the history of the N'ew York Academy of Sciences 

 the library has been so much used by scientists and naturalists in the 

 vicinity as during the year just past. The files, in conjunction with 

 those of the American Museum of Natural History, now form a remark- 

 ably complete library in the subject of Natural History, as well as in 

 the proceedings of the Learned Societies of the world. 



The uncertainty of the foreign mails and the disturbed political situa- 

 tion in Europe have caused an almost complete cessation of exchanges 

 with that part of the world; on the other hand, opportunity has thus 

 been afforded for promoting a more intimate affiliation with our sister 

 societies in South America. 



Eespectfully submitted, Ealph W. Tower, 



Librarian.
