THE AMERICAN MATHEMATICAL SOCIETY. 



The twelfth annual meeting of the Am- 

 erican Mathematical Society was held at 

 Columbia University on Thursday and 

 Friday, December 28-29, 1905, simultane- 

 ously with the meetings of the American 

 Physical Society and the Astronomical and 

 Astrophysical Society of America. Large 

 attendance and extensive programs charac- 

 terized this three-fold gathering, in itself a 

 noteworthy scientific occasion. Community 

 of interest received due attention. A joint 

 session of the Mathematical and Physical 

 Societies was held on Friday afternoon for 

 the purpose of hearing Professor V. F. 

 Bjerknes, of the University of Stockholm, 

 who spoke on 'Experimental Demonstra- 

 tion of Hydrodynamic Action at a Dis- 

 tance.' On Friday evening about ninety 

 representatives of the three societies at- 

 tended a dinner organized in honor of 

 Professor Bjerknes. The common luncheon 

 between each day's sessions afforded an 

 excellent opportunity to renew and make 

 acquaintance and to compare notes, scien- 

 tific or otherwise. Informal gatherings 

 were also held on Thursday evening. 



The attendance at the four sessions of 

 the Mathematical Society included sixty- 

 six members, being a slight increase over 

 the highest previous record. President W. 

 F. Osgood occupied the chair, being re- 

 lieved at the Friday afternoon session by 

 Professor E. W. Brown. President Carl 

 Barus, of the Physical Society, presided 

 during the joint session. The following 

 persons were elected to membership : Mr. 

 R. L. Borger, University of Missouri ; Pro- 

 fessor "VV. B. Cairns, Ursinus College ; Mr. 

 A. J. Champreux, University of California 

 Dr. Emily Coddington, New York, N. T. 

 Dr. F. J. Dohmen, University of Texas 

 Professor 0. E. Glenn, Drury College ; Mr, 

 E. S. Haynes, University of Missouri 

 Professor J. H. Jeans, Princeton Univer- 

 sity; Mr. A. R. Maxson, Columbia Univer- 



sity; Professor J. F. Travis, Georgia 

 School of Technology ; Professor Vito Vol- 

 terra. University of Rome ; Miss Mary 

 E. G. Waddell, Orono, Canada. Nineteen 

 applications for admission to membership 

 were received. The total number of mem- 

 bers is now 504, a .net gain of 31 during 

 the year 1905. 



Reports were received from the treas- 

 urer, librarian and auditing committee. 

 These reports will appear in the Annual 

 Register of the society. The number of 

 papers read at all meetings during the year 

 was 147, as against 148 in 1904. The total 

 attendance of members was 280 ; 161 mem- 

 bers attended at least one meeting during 

 the year. The library now contains about 

 2,300 bound volumes. The treasurer's re- 

 port shows a balance of .$3,833.01 on hand 

 December 16, 1905; of this balance 

 $2,132.58 is credited to the life member- 

 ship fund.

 vStringham.

R. G. D. RiCHAEDSON : ' Multiple Improper 

 Integrals.' 



A. B. Frizell: 'On the Continuum Problem 

 (preliminary eommunication) . 



D. R. CuETiss: 'The Vanishing of the Wrons-
