Dr. Sharp reports that 64 slides have been purchased and that Dr. 
H. A. Pilsbry has presented 14, making the number of slides in the col- 
lection 1,447. The Schaeffer collection of some 2,000 slides have not 
yet been catalogued. It is hoped that this will be done during the 
coming spring. 
It gives me pleasure to acknowledge my obligation to my assistant, 
William J. Fox, for efficient service, both in the Library and in the issue 
and distribution of the Academy’s publications, during my attendance 
at the meeting of the American Library Association in Portland,

provided for storage of small birds and insects, as well as 245 Schmitt
