590 PROCEEDINGS OF THE ACADEMY OF [DeC, 



concluding number was not issued until later, so that it will be in- 

 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 as 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 Wm. J. Sinclair, 

 H. R. M. Landis, H. T. Wolf and T. Guilford Smith. 



A successful meeting of the American Ornithologists' Union was 

 held in the Lecture Hall and Reading Room, November 13-16. 



The Committee on Instruction and Lectures reports that the 

 usual course of free popular evening lectures was conducted in 

 conjunction with the Ludwick Institute, January 9-April 20, 1911, 

 this being the second series delivered in the new Lecture Hall of the 

 Academy. 



Five lectures on Bird Life about Philadelphia were delivered by 

 Mr. Witmer Stone; three on the Conservation of Human Energies 

 and Resources by Dr. Seneca Egbert; two on the Mammalia by 

 Dr. Spencer Trotter; five on Scientific Explorers of America and 

 their Discoveries by Dr. H. A. Pilsbry; five on Entomology by

 tion and its Significance by Dr. J. Percy Moore. 



Beginning September 13, 1911, an afternoon course was given to 

 students of the Girls' High Schools of Philadelphia, who visited the 

 Academy in company with their teachers. This course was very 

 largely attended. Two lectures each were delivered by the following 

 speakers: Mr. Witmer Stone on Local Birds, Dr. J. Percy Moore 

 on Mammals and Reptiles, Dr. Henry Skinner on Insects, Mr. 

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



Early in the year resolutions were adopted by the Council approv- 

 ing of a fitting celebration of the Centenary of the Academy on the 

 19th, 20th, and 21st of next March. The President appointed a 

 committee of forty-one to make arrangements for such celebration.
