Notwithstanding the fact that the annual appropriation for the 

 purchase of books was somewhat curtailed, the additions made to 

 the library number 1,555 more than those of the preceding year. 

 This is partly accounted for by Mrs. Gazzam's gift of 275 dupli- 

 cate volumes of Pennsylvania Geological Survey Reports, and the 

 transfer from the library of the Entomological Section of 709 reports 

 of Agricultural Stations, but it is mainly owing to successful efforts 

 to secure exchanges and deficiencies. 



Thirty-two pamphlets received in duplicate from the Department 

 of Agriculture were, as required by law, returned to Washington. 



An oil portrait of Dr. John L. LeConte, by L. G. Seybert, the 

 gift of Mrs. LeConte, was formally presented at the meeting of April 

 18, by Dr. Henry Skinner, who commented on the work and services 

 of the distinguished entomologist. 



I am indebted to my assistant, Mr. William J. Fox, for the per- 

 formance of much of the routine work of the year, thereby enabling 

 me to give more time than would otherwise have been possible to 

 the interests of the approaching Centenary, about which more is said 

 in the Report of the Recording Secretary. 



My junior assistant, Mr. Furman Sheppard Wilde, has also been, 

 in the discharge of his duties, intelligent and loyal. 



Edward J. Nolan, Librarian.
