332 ROCHESTER ACADEMY OF SCIENCE. [Jan. I4, 



Exchanges. Our Proceedings have been donated to several hun- 

 dred scientific and educational institutions in foreign countries as well 

 as America, and have carried the name and fame of Rochester around 

 the world. The list of " Exchanges " includes at present nearly 200 

 institutions in the United States and over 300 in foreign countries. 



Library. The most valuable piece of property owned by the 

 Academy is its library, now deposited, under suitable contract, in the 

 Library of the University . It has been accumulated almost entirely 

 since 1891 as a result of our system of exchanging publications with 

 other societies the world over. It is composed largely of the proceed- 

 ings or transactions of scientific societies and museums, which publica- 

 tions are difficult to obtain except by way of exchange, and now 

 includes about 5,000 volumes and pamphlets. 



Collections. Something has been done in the way of making 

 collections representative of the local natural history. The Herbarium, 

 especiallv, can be mentioned with pride. It is another monument to 

 the successful labors of the Botanical Section. Through the gifts of 

 the members, and by donations and exchange it now includes about 

 15,000 specimens. Among special collections in the herbarium is the 

 collection of ferns, numbering about 1,500 specimens, presented to 

 the Academy by Mr. C. W. Seelye. (See Proceedings, Vol. 2, 

 page 180 ; volume 3, page 195.) 



The collection of local molluscan shells presented to the Academy 

 by Mr. John Walton is on deposit in the Zoological Museum of the 

 University. It has recently been rearranged and relabelled by Mr. 

 George H. Chadwick, and is a fine display of a local fauna. The 

 suite of local fossils donated by Mr. A. L, Arey is a partial represen- 

 tation of the ancient life of the region as preserved in the Rochester 

 rocks. It is deposited in the Geological Museum of the University. 



The Robert Bunker Collection of insects, handsomely mounted 

 and cased, has been housed for a number of years in the vestibule of 

 Sibley Hall. In 1882 Mr. Robert Bunker transferred the collection 

 to three trustees, Adelbert Cronise, Joseph T. Ailing and H. F. 

 Atwood, with the verbal understanding that it should remain in the 

 custody of the Academy under conditions of proper housing and care. 

 The handsome mounting and casing of the collection was made by 

 special contributions of money secured by Mr. Cronise and Major 

 Streeter.
