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 t6 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.
