Five hundred and forty-three volumes have been bound, being 
but little more than the unbound accessions of the year. The accu¬ 
mulation of unbound volumes has been nearly all put in proper shape 
by the liberal appropriations of the few preceding years. 
A careful count of the books now in the possession of the Academy 
furnishes the following statistics:

This is an increase of 15,912 volumes since the enumeration of 1901. 
In view of the strictly special character of the library this should be 
regarded as a gratifying exhibit. It represents the steady current 
growth of the collections, no large libraries having been received 
en bloc. The separate pamphlets have not been counted, but an 
estimate has been made of the number of volumes those still unbound 
would make if arranged uniformly with the rest of the collection. 
Many of the volumes in the library of the Entomological Section 
are duplicates of those on the shelves of the Academy. There is an 
apparent falling off of 121 volumes on Conchology instead of an in¬ 
crease, but this is accounted for by the fact that the Conchological 
journals were formerly placed with the special books on that subject,
