PROCEEDINGS OF THE ACADEMY OF 
[Dec., 
logical Society (Entomological Section of the Academy), 400 pages, 
3 plates; Manual of Conchology, 108 pages, 20 plates. The entire 
issue for the year, therefore, amounts to 2,358 pages and 123 plates. 
Nineteen members and four correspondents have been elected. 
The deaths of twelve members and of six correspondents have 
been announced, while three members have resigned. 
More than a mere record should be made of the loss sustained 
by the Academy in the deaths of Edward Potts and Thomas Harrison 
Montgomery. Mr. Potts had been forced by impaired health 
to discontinue, a few years ago, his active association with the 
Academy, but his interest in science remained unabated to the last. 
His work on the natural history of the fresh-water sponges, the 
results of which the Academy had the honor of publishing, has 
been recognized as of singular accuracy and thoroughness. 
Dr. Montgomery was the first contributor to the commemorative 
volume, and the announcement of his death at the first session 
of the centenary meeting was a pathetic incident of the proceedings. 
Appropriate action was taken by the Academy, an appreciative 
minute, prepared by Dr. Calvert, having been placed on the minutes 
and published. 
The Hayden Medal, on the recommendation of the properly con¬ 
stituted committee, was awarded to Professor John C. Branner, 
of the Leland Stanford Jr. University, in recognition of his dis¬ 
tinguished work in geology. 
Daniel J. Fay, Robert Rosenbaum, and Delos E. Culver have 
served terms as Jessup Fund students. 
The will of the late Mrs. Catherine E. Beecher provides for the 
endowment of the J. F. Beecher Memorial Laboratory for the 
study of Biology and Anthropology in the Academy. The amount 
of the fund, not yet definitely reported, is to be invested for ten 
years before the income can be available. The proper officers 
have been instructed to prepare the papers required by the accept¬ 
ance of the legacy. 
The popular evening course of free lectures, conducted in con¬ 
junction with the Ludwick Institute, was given as usual on Monday 
and Thursday evenings, January 8 to March 7:— 
Three lectures on Familiar Birds and their Life Histories were 
delivered by Air. Witmer Stone; one on The Organization of the 
Pennsylvania Department of Health by Dr. B. F. Royer; one on 
The Purity of the Streams of Pennsylvania by Air. F. Herbert 
Snow; three on Entomology by Dr. Henry Skinner; three on Problems
