REPORT OF 'l"HE LIBRARIAN. 



(Abstract.) 



The exchange list of the Society has been increased during 

 the year by the addition of the publications of ten societies, in- 

 cluding the publications of the Geological Survey of India, the 

 Royal University of Norway, the German Scientific Society of 

 Santiago Chili, the Entomological Society of Washington, etc., 

 etc. 



There have been added to the library during the year, by 

 donation and exchange, about 400 books and pamphlets. The most 

 valuable being the volumes of the Geological Survey of India. 

 These volumes have been bound in plain substantial binding and 

 the forty volumes contain a vast amount of valuable material. 



Next to this set is the publications of the Pennsylvania 

 Geological Survey, nearly all of which are now in the Society's 

 library. 



Donations have been numerous. The largest was from the 

 Estate of Dr. E. S. Wayne received through Dr. O. D. Norton. 

 This consisted of about 100 books and pamphlets, many of them of 

 great value. 



A new book case has been ordered and will soon be ready to 

 be placed in the library. Geo. W. Harper, Librarian.
