EEPOET OF THE LIBEARIAIST 



The New York Academy of Sciences has received during the current 

 year by gift and exchange only one hundred one volumes and some two 

 hundred fifty numbers, representing about one half of the normal acces- 

 sions. Because of the insecurity of transportation, practically none of 

 the learned societies in Eussia, Germany, Austria, Italy and the Balkan 

 States are dispatching their publications. 



The Library of the Xew York Academy of Sciences finds an increased 

 usefulness each year, with an appreciation on the part of the scientists 

 for the admirable collection which it possesses. 

 Eespectfully submitted, 



E. W. TOWEE, 



Librarian.
