SOCIETIES AND ACADEMIES 

 AMERICAN MATHEMATICAL SOCIETY 



At the regular meeting of the society, held 

 at Columbia University on Saturday, April 

 27, an especially attractive feature of the 

 program was Professor W. F. Osgood's presi- 

 dential address on ' The Calculus in our Col- 

 leges and Technical Schools.' The address 

 will appear in the June number of the Bul- 

 letin of the society. The attendance at the 

 April meeting, always ranking next to that 

 of the annual and summer meetings, exceeded 

 on this occasion all previous records, amount- 

 ing to about seventy, including sixty-one 

 members. 



President H. S. White occupied the chair 

 at the two sessions. The council announced 

 the election of the following new members : 

 Dr. Alfred Ackermann-Teubner, Leipzig, Ger- 

 many; Dr. J. W. Bradshaw, University of 

 Michigan; Professor H. E. Cobb, Lewis Insti- 

 tute, Chicago, lU.; Mr. S. A. Corey, Hiteman, 

 la.; Professor Floyd Field, Georgia School of 

 Technology; Mr. G. W. Hartwell, Columbia 

 University; Chancellor C. C. Jones, Univer- 

 sity of New Brunswick; Mr. Joseph Lipke, 

 Columbia University ; Professor Francis Regis, 

 Christian Brothers College, St. Louis, Mo.; 



Mr. H. P. Stillwagen, Yeatman High School, 

 St. Louis, Mo. Seven applications for ad- 

 mission were received. The total membership 

 of the society on May 1 was 560. 



Following the plan recently adopted, ab- 

 stracts of the papers so far as available had 

 been printed and issued to the members in 

 advance of the meeting. In this way it is 

 hoped to secure a more intelligent interest in 

 the papers and to promote criticism and dis- 

 cussion. 



The date of the summer meeting, to be held 

 at Cornell University, was fixed for Thursday 

 and Friday, September 5 and 6. 



By no means the least enjoyable feature of 

 the meeting was the usual dinner in the even- 

 ing, attended on this occasion by over twenty 

 of the members. 



The following papers were read at this 

 meeting : 



G. A. Bliss : ' A new form of the simplest prob- 

 lem of the calculus of variations.' 



R. D. Caemichaex : ' Multiply perfect even num- 

 bers of five different primes ' ( preliminaiy com- 

 munication). 



L. P. EisENHAKT: 'Transformations of surfaces 

 whose lines of curvature are represented on the 

 sphere by an isothermal system.' 



F. L. Gbiffin: 'The variation of the apsidal 

 angle in certain families of central orbits.' 



F. L. Geiffin : ' The solutions of central force 

 problems as functions of the constant of areas.' 



F. Ii. Geiffin : ' Note on a simple example of a 

 central orbit with more than two apsidal dis- 

 tances.' 



G. A. MiLLEE: ' Note on the commutator of two 

 operators.' 



J. E. Weight: 'Arrangement of ovals of a 

 plane sextio curve.' 



W. F. Osgood: Presidential address — 'The cal- 

 culus in colleges and technical schools.' 



Ida M. Schottenfels : ' Group matrices.' 



0. E. Steomquist: 'An inverse problem of the 

 calculus of variations.' 



R. G. D. RiCHAEDSON: 'On the integration of a 

 series term by term.' 



A. L. Undeehill : ' Invariants of the function 

 F(x, y, x', y') under point and parameter trans- 

 formations connected with the calculus of varia- 

 tions.' 



Edwaed Kasnee : ' The motion of particlea 

 under conservative forces.'
