AMERICAN MATHEMATICAL SOCIETY 



The two hundred and fifth regular meeting of 

 the society was held at Columbia University on 

 Saturday, October 25, 1919, extending through the 

 usual morning and afternoon sessions. The at- 

 tendance included forty-nine members. 



Vice-president G. D. Birkhoff occupied the chair. 

 The council announced the election of the follow- 

 ing persons to membership in the society: Dr. C. 

 C. Camp, University of Illinois; Professor Carl J. 

 Coe, University of Michigan; Dr. Teresa Cohen, 

 Johns Hopkins University; Mr. W. E. Heal, U. S. 

 Bureau of Plant Industry; Dr. C. A. Nelson, Uni- 

 versity of Kansas; Mr. J. L. Walsh, Harvard Uni- 

 versity. Four applications for membership were 

 received. 



A list of nominations for oflBcers for the com- 

 ing year was adopted and ordered printed on the 

 official ballot for the annual election. A commit- 

 tee was appointed to audit the treasurer's ac- 

 counts for the current year. Propositions for es- 

 tablishing a board of custodians for the society's 

 property and for issuing a new catalogue of the 

 library were laid over for action at the annual 

 meeting.

 ^ Motion in a resisting medium: J. K. Whitte- 

 more.

 filosed point sets with connected sum: Anna M. 

 ^ulliken.

 theory of modular covariants: Olive C. Hazlett.

 fhe principle of inversion in the theory of num- 

 bers: R. D. Carmichael. 



I Note on the theory of integral functions of the 

 first class: R. D. Carmichael.

 meters: Anna J. Pell. 



I Note on stable periodic orbits: G. D. Birkhoff.

 the air aloft: A. A. Bennett. 

 , The probable error of a small number of rounds: 

 A. A. Bennett.

 tions: A. A. Bennett. 



, The sign of the distance in analytic geometry: 

 A. A. Bennett. 

 , Invariants of infinite groups in the plane: E. P. 



glMONDS. 



, The motion of n bodies, under any forces, start- 

 ing from rest: Edward Kasneb. 



The San Francisco Section met at the University 

 of California on October 25. The annual meeting 

 of the society will be held at Columbia University 

 on December 30-31 and will be followed by that 

 of the Mathematical Association of America on 

 January 1-2. The Chicago and the Southwestern 

 Sections will meet at St. Louis with the American 

 Association for the Advancement of Science.
