direction of the Council, no volumes or parts of journals or periodicals 
may be borrowed without the special consent of the Librarian, who 
must be reasonably sure, before the publication is sent out, that the 
interests of those working on the premises will not be interfered with 
by the loan. 
As required by the By-Law, a separate list of books that can be 
borrowed is being prepared and is nearing completion. 
A very desirable subject index to the map collection has been 
prepared by Mr. Fox. 
Forty-seven volumes of works not connected with the Academy’s 
interests have been transferred to the Free Library of Philadelphia. 
A framed photograph of Rembrandt Peale’s oil portrait of Reuben 
Haines, who served most efficiently as Corresponding Secretary 
from February, 1814, to December, 1831, has been presented by his 
grandson, Reuben Haines. 
A framed photograph from life of the late Dr. Benjamin Sharp 
has been received from Mrs. Sharp. 
Through the liberality of a number of subscribers, there has been 
obtained a replica of the portrait of Baron Yon Humboldt, painted 
from life in 1856 by J. R. Lambdin, and now in the rooms of the Ameri¬

by the President of the Academy.

J. Fox and Furman Sheppard Wilde, both in the Library and in 
connection with the issue of the publications.

The number of visitors to the Museum has steadily increased, 
especially classes from the schools of Philadelphia and vicinity

At the last session of the State Legislature the sum of 810,000 was
