L ( ,. ; i« a i. S« >ciety (Entomological Section of the Academy), 400 pages, 

 3 plates : Manual of Conchology, 168 pages, 20 plates. The entire 

 issue lor 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. Air. 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: —
