THE AMERICAN ASSOCIATION FOR TBE 



ADVANCEMENT OF SCIENCE AND 



CONVOCATION WEEK. 



The permanent secretary of the Ameri- 

 can Association for the Advancement of 

 Science has compiled an abstract of the 

 communications printed in Science early 

 in the year in regard to the meetings of 

 the American Association and the special 

 scientific societies, which is here printed, 

 in order that further discussion may be 

 elicited either in the columns of Science 

 or at the approaching meeting of the asso- 

 ciation. 



Nichols, E. L. (29 Jan., '04, No. 474, p. 192). 

 The plan of convocation week is a 'distinct 

 step in advance. * * * The general feeling 

 in the vcest seems to be for summer meetings; 

 in the east for winter meetings. Many of us 

 would be glad of a choice, with the privilege 

 of attending either or both. Summer meetings 

 should be held in some attractive and acces- 

 sible resort; in mountains, on lakes or at the 

 seashore. Select earliest possible date after 

 closing of colleges and thus avoid the summer 

 rush to these places. Bringing together of 

 various afiiliated societies at a common meet- 

 ing place helps to mitigate one of the most un- 

 fortunate features of modern specialization in 

 science — the separation of men of science into 

 small groups. Question of expense of two 

 meetings a year not worthy of consideration. 

 It is imperative that the association afford 

 those members who can not attend the winter 

 meetings an opportunity for intercourse with 

 kindred spirits at time and place possible to 

 them.

 pp. 192-4).
