LIBRARY. 



The Library numbers over 18,000 titles, and is especially 

 rich in sets of the publications of American and Foreign Societies. 

 In this respect it is one of the most complete in this country. It 

 is now shelved in a special room of the Library building at Co- 

 lumbia University, and is accessible to Members from 8 a.m. to 

 10 P.M. every day of the year. 



MEETINGS. 



The Academy at present enjoys the hospitality of Columbia 

 University in the use of Hamilton Hall. There is, however, no 

 official connection between the Academy and the University. 

 Meetings are held every Monday at 8 p.m., from October to 

 May, inclusive. The Academy meets in sections on successive 

 Mondays in the following order : Astronomy and Physics ; 

 Biology (Zoology, Physiology, Botany) ; Geology and Mineral- 

 ogy; Anthropology, Psychology and Philology. Other sections 

 may be formed by a vote of the Council. Each of the sectional 

 evenings is devoted mainly to scientific papers and discussions. 

 All the meetings are open to the public and are announced, with 

 the subjects of the papers to be read, in the bulletins of the 

 Scientific Alliance of New York. 



POPULAR LECTURES. 



The Academy is largely aided in its scientific work by its 

 general membership, and the course of illustrated popular lec- 

 tures arranged for each winter is specially for the benefit of the 

 general Members and the public. The subjects of the lec- 

 tures are chosen from different branches of science, and are de- 

 signed to present in a popular manner the latest results of research. 

 Persons desiring to join the Academy or support its scientific 

 work by subscription should address
