The Curator of Entomology made a revised report of 

 the collection of Insects belonging to the Society, and 

 especially on the addition made by the purchase of the 

 cabinet of the late Dr. T. W. Harris, and his valuable 

 manuscripts. 



The department of native insects in Dr. Harris's cabinet has a 

 peculiar value as containing many typical specimens of species 

 described by himself, Say, and other naturalists, and also from its 

 completeness in all its parts. It contains — 



4838 specimens of 2241 species of Coleoptera. 



In all, 9758 specimens of 4660 species. This does not include a 

 considerable number of unclassified specimens. The cabinet is 

 in good condition. The Curator suggested the purchase of his 

 scientific library, rich in entomological works not elsewhere to be 

 met with in this vicinity, and forming a most desirable accompa- 

 niment to his collections. 



Mr. Stodder exhibited a specimen of polished encrinal 

 limestone, from the vicinity of Davenport, Iowa. 



Mr. F. B. Meek, of Washington, D. C, was elected a
