Library. — The history of the library for the past year has 

 been one of constant growth. The number of individual 

 donors has increased, and there have been more accessions 

 from the individuals and institutions on our exchange list 

 than during the preceding year. The principal accessions 

 have come from General Egbert L. Viele and Mr. Frederick A. 

 Constable, the volumes from the latter pertaining specially to 

 conchology. The total number of volumes, parts and pamph- 

 lets received is equivalent to 2,619 bound volumes, making 

 the total number of volumes or their equivalent in the library 

 at the present time 55,308. The books have been very ex- 

 tensively used by members and visitors, as well as by our 

 scientific staff, but there have been calls for hundreds of 

 books not on our shelves, which, however, should be in our 

 possession. The branches of natural science which need 

 especial development in the line of books and periodicals are: 

 Forestry, Herpetology, Anthropology, Invertebrate Zoology, 

 Mineralogy and Mining. A considerable sum, furthermore, 

 could be used to advantage in the purchase of missing num- 

 bers and parts of scientific periodicals.
