SOCIETIES AND ACADEIIIES- 



THE ANNUAL MEETING OF THE NEW YOEK 

 ACADEMY OF SCIENCES, FEBEUABY 26, 1900. 



Professor Henry F. Osborn, President of 

 the Academy, opened the meeting with a brief 

 address in which he spoke particularly of the 

 needs of the Academy in reference to a perma- 

 nent home, and a larger publication fund ; of 

 the work of the sections of the Academy, par- 

 ticularly of that of [the Section of Anthropology 

 and Psychology, in association with the recently 

 organized Ethnological Society ; and of the 

 Section of Astronomy and Physics, which has 

 lately added Chemistry to its field of operations. 

 Professor Osborn paid brief tribute to certain 

 of our distinguished Honorary members who 

 have died during the year, particularly to Pro- 

 fessor Bunsen, Dr. Geinitz, Sir William Daw- 

 son, and Sir William Flower. 



The Recording Secretary reported a total of 

 333 resident members, and analyzed the 82 

 papers given before the Academy during the 

 last year, as to their subjects, showing that the 

 largest attention has been given to anthropol- 

 ogy, astronomy, geology, paleontology, petrog- 

 raphy, physics, and zoology. The Recording 

 Secretary also reported that the annual recep- 

 tion and exhibition which was held in April, 

 in the American Museum of Natural History, 

 was, like its predecessors, extremely successful. 

 For the first time since the reception has been 

 held in the American Museum it was possible 

 to have an unoccupied room, whereby there 

 was no confusion between the Academy and 

 Museum exhibits. The same plan will be fol- 

 lowed during the coming year. The Academy 

 feels that it owes a great deal to the President 

 and Trustees of the American Museum of Nat- 

 ural History, for their kindness and courtesy 

 in allowing the Annual Reception to be held in 

 the Museum, under such favorable auspices, 

 and at such a moderate expense to the Academy. 



The Council feels that the success and in- 

 creased interest evident in the meetings since
