' Mathematics and Biology ' was of especial 

 interest at this time on account of its bearing 

 upon the principle of variation and mutation. 



The recently adopted rule of not allowing 

 papers to go on the program unless an ab- 

 stract had been handed in by the author was 

 adhered to by the program committee. This 

 committee was enlarged for the coming year 

 so as to have five members, one for zoology, 

 one for botany, one for geology and physiog- 

 raphy, one for archeology, anthropology and 

 ethnology, and one for mathematics, chemistry 

 and physics. 



The next annual meeting will be held at the 

 University of Cincinnati during the Thanks- 

 giving recess, 1905. The following officers 

 were elected: 



President — Herbert Osborn, Columbus. 



First Vice-President— C. W. Dabney, Cincin- 

 nati. 



Second Vice-President— F . M. Comstock, Cleve- 

 land. 



Secretary — L. B. Walton, Gambler. 



Treasurer — J. S. Hine, Columbus. 



Member Board of Trustees— C. J. Herriek, 

 Granville. 



Elective Members Executive Committee — S. H. 

 Williams, Oxford, and F. C. Waite, Cleveland.

DISCUSSION AND CORRESPONDENCE. 



cox'^-ocation week. 

 In the earlier years of the American Associa- 

 tion it had at least four important functions: 

 (1) It gave opportunity for expert scientific dis- 

 cussion. (2) It fostered the scientific spirit 

 and developed scientific interest in the people 

 of the land (a) by admitting non-expert as 

 well as expert membership, thus giving an op- 

 portunity for non-expert discussion, (i) by as- 

 sembling popular or semi-scientific audiences, 

 (c) by a peripatetic system of meetings in 

 which few places were visited more than once. 

 (3) It promoted the solidarity of the scien- 

 tific body by affording opportunity for per- 

 sonal acquaintance and intercourse (a) of 

 students of the same subject, (h) of students 

 of different subjects. (4) It undertook the
