cluded in the statistics of publication of next year. 
Thirty members and six correspondents have been elected. The 
deaths of seven members and fourteen correspondents were an¬ 
nounced. In recording the death of the Rev. Henry C. McCook, 
the Secretary referred briefly to the value of his work and to the very 
important services rendered by him to the Academy a< Vice-Presi¬ 
dent, and especially in connection with the Committee on Instruc¬ 
tion and Lectures. A much more adequate memorial has been 
published by Dr. Philip P. Calvert in the current volume of the 
Entomological News. 
The appointments made by the President on the recommendation 
of the Council are noted in the report of the Corresponding Secretary. 
Resignations of membership were received from Win. J. Sinclair,

The Committee on Instruction and Lectures reports that the 
usual course of free popular evening lectures was conducted in

Stewardson Brown on Plants, and Dr. Henry A. Pilsbry on Alollusks.
