previous records. An enjoyable social feature 

 of the meeting was the dinner at the Hotel 

 Marlborough on Friday evening attended by 

 fifty persons, including representatives of the 

 American Physical Society, which was in ses- 

 sion on Friday. 



At the annual election, on Saturday morn- 

 ing, the following officers and members of the 

 Council were chosen : Vice-Presidents, Maxime 

 Bocher, Franlv Morley; Secretary, F. N. Cole; 

 Treasurer, W. S. Dennett; Librarian, D. E. 

 Smith; Committee of Publication, F. N. 

 Cole, Alexander Ziwet, Frank Morley; Mem- 

 bers of the Coiincil to serve until December, 

 1904, Pomeroy Ladue, G. A. Miller, P. F. 

 Smith, E. B. Van Vleck. The President of 

 the Society, Professor E. H. Moore, holds 

 office for a term of two years expiring at 

 the annual meeting of 1902. Resolutions 

 were adopted by the Council expressing appre- 

 ciation of the services of the retiring Librari- 

 an, Professor Pomeroy Ladue, who has held 

 that office since 1895. 



The following persons were elected to mem- 

 bership in the Society: R. E. AUardice, Stan- 

 ford University; Miss Grace Andrews, Col- 

 umbia University; S. E. Brasefield, Michigan 

 Agricultural College; W. E. Brooke, Univer- 

 sity of Minnesota; T. C. Esty, University of 

 Rochester; L. L. Jackson, State Normal 

 School, Brockport, N. T. Seven applications 

 for membership were received and laid over, 

 under the by-laws, for action at the February 

 meeting. 



Reports were received from the secretary, 

 treasurer and librarian. These reports will 

 appear in the Society's Annual Register now 

 in preparation. The Society has now 378 

 members, a net gain of 21 over last year. 

 There are 17 life members. The total at- 

 tendance of members at the meetings of 1901 

 was 2.30, the number of papers read 140, in 

 both cases a large increase over previous years. 

 The Treasurer's report shows a balance of 

 over two thousand dollars. The Transactions 

 has just initiated its third annual volume; 

 the Bulletin has been issued since 1891. An 

 especially important event of the past year 

 was the deposit of the library of the Society 

 in the charge of Columbia University, through 



whose generous action the books will now be- 

 come available for the use of the members. 

 A catalogue will soon be issued and steps will 

 be taken to extend and complete the collection. 

 Following is a list of the papers read at the 

 annual meeting. It may be added that the 

 Chicago Section of the Society issued a pre- 

 liminary program of nineteen papers for its 

 meeting at Evanston, Bl., on January 2-3, 

 1902.
