REPORT OF THE RECORDING SECRETARY. 
The Recording Secretary respectfully reports that late in Sep¬ 
tember, he was disabled by an affection of the right side which has

The Secretary, in the hope of being able to resume the duties of 
his offices with the opening of the New Year, has been sustained 
by the sympathy of the President and the other administrators of 
the Academy, to whom, and to other friends, he returns his sincere 
thanks. 
The following report, and that of the Librarian, have been prepared 
by Mr. Fox, whose efficiency is cordially recognized by the Secretary
