The Curators would also acknowledge the efficient work of their 
assistants, Messrs. Witmer Stone and Samuel N. Rhoads, to whose 
earnestness and fidelity the successful progress of the museum work 
is largely due ; and they also express their appreciation of the work 
of the taxidermist, Mr. D. N. McCadden, and the valuable assist¬ 
ance of the students of the Jessup Fund, Miss Helen M. Higgins, 
Messrs. Henry W. Fowler, H. C. Borden, Win. J. Gerhard and 
E. G. Vanatta. 
The interest of the general public in the museum is shown by the 
large attendance of visitors during the year, while specialists in

Specimens have been loaned to Messrs. R. Latchford, F. W. Stokes, 
O. F. Cook, H. C. Mercer, Professors B. W. Evermann, Chas. E.
