802 PROCEEDINGS OF THE ACADEMY OF [Dec. , 
of 617 Muybridge plates illustrating animal motion. They will 
fill six portfolios and go far toward the completion of the Academy’s 
collection of these interesting plates, of which previously there 
were but 103 in the Library. 
Four hundred and ninety-eight volumes have been bound. 
A death-mask of Dr. Joseph Leidy, whose memory is held in 
deserved esteem, has been presented by his nephew, Dr. Joseph 
Leidy, Jr. 
The decrease in the number of volumes bound and the slight 
falling off of receipts from those reported last year are consequent 
on the absence of the Librarian from May until October, four 
months’ vacation having been kindly granted him by the Council 
for the improvement of his health, an end which was measurably 
secured by a prolonged stay in Italy. He has great pleasure in 
acknowledging his obligation to his assistant, Mr. William J. Fox, 
who during that period performed the routine work of the Library 
and also acted as Recording Secretary most acceptably. 
All of which is respectfully submitted, 
Edward J. Nolan, 
Librarian. 
REPORT OF THE CURATORS. 
The year just past has been one of prosperity. While the soci- 
ety’s income is small compared with that of many other institutions 
of like character, the increase in its scientific collections has been 
large, and the results obtained in original research have been the 
most extensive in its history. 
The buildings and the collections in the care of the Curators 
have been kept in excellent condition during the year, while many 
improvements have been effected. 
Additional space has been provided for the Entomological depart- 
ment by enclosing another section of the first floor of the old 
Museum. The taxidermist’s quarters in the new wing have been 
partitioned off from the rest of the basement and heated. 
An enlarged system of steam pipes, covered with magnesia, has 
been introduced in the old building.
