176. The total attendance of members at 

 the ten meetings of the year was 350; 192 

 members attended at least one meeting. 

 The total membership of the society is now 

 547, a gain of 43 during the year. 



The publication of the New Haven col- 

 loquium lectures, delivered at the last sum- 

 mer meeting, has been generously under- 

 taken by Yale University. The volume 

 will probably appear next fall. 



The following papers were read at the 

 meeting : 



S. E. Slocum : ' The rational basis of mathe- 

 matical pedagogy.' 



F. L. Griffin : ' On the law of gravitation in 

 binary systems.' 



James McMahon: 'A differential property of 

 the lamellar vector field.' 



J. I. Hutchinson: 'A method of constructing 

 the fundamental region of a discontinuous group 

 of linear transformations.' 



James Pieepont : ' Multiple integrals.' 



Oswald Veblen : ' Collineations in a finite pro- 

 jective geometry.' 



W. R. LoNGLET : ' Some particular solutions in 

 the problem of n bodies.' 



Max Mason ; ' The expansion of an arbitrary 

 function in terms of normal functions.' 



R. D. Caemichael: 'On Euler's ^-function.' 



Arthue Ranum : ' On the group of classes of 

 congruent matrices.' 



W. B. Carver : ' Sets of quadric spreads con- 

 nected with the configuration Tn, r- 



C. J. Keysee : ' Circle range transversals of 

 circle ranges in a plane: a problem of construc- 

 tion.' 



C. J. ICeysee : ' Concerning the analytic treat- 

 ment of geometric involution.' 



A. B. Coble: 'A generalization of the plane 

 Hesse configuration.' 



A. B. Coble : ' Involutory Cremona trans- 

 formations.' 



W. E. Story : ' Denumerants of double diflfer- 

 entiants.' 



Virgil Sny'dee : ' Birational transformations of 

 curves of high genus.' 



T. E. McKinney : ' On the continued fractions 

 representing properly and improperly equivalent 

 real numbers in a system of continued fractions 

 depending on a variable parameter.' 



H. E. Hawkbs : ' On elementary divisors.' 



E. B. Wilson : ' Rotations in higher dimen- 



Edwabd Kasnee : ' Systems of extremals in the 

 calculus of variations.' 



Edward Kasnee : ' The motion of a particle in 

 a resisting medium.' 



R. P. Stephans : ' Note on a system of curves 

 of class n and order 2(n-l).' 



D. E. Gillespie: 'On the construction of an 

 integral of Lagrange's equation in the calculus of 

 variations.' 



F. R. Sharpe : ' The general circulation of the 

 atmosphere.' 



The following papers from the program 

 of Section A of the American Association 

 for the Advancement of Science were also 

 laid before the society : 



G. B. Halsted : ' The sect carrier and the set 

 sect.' 



Harris Hancock : ' On a fundamental theorem 

 of Weierstrass by means of which the theory of 

 elliptic functions may be established.' 



G. A. Miller : ' On the minimum number of 

 operations whose orders exceed two in any finite 

 group.' 



The informal dinner, always arranged in 

 connection with each meeting of the society, 

 adds much to the pleasure of these occa- 

 sions. Despite the many distractions inci- 

 dent to the general gathering of scientists, 

 over forty members attended the dinner on 

 Friday evening and passed a few pleasant 

 hours in social intercourse and renewal of 

 old acquaintance. 



The Chicago Section met on the same 

 days as the society. The next meeting of 

 the society, and also of the San Francisco 

 Section, falls on Saturday, February 23.
