REPORT OF THE COMMITTEE ON CONVOCATION

 allegiance of a large number of important 

 educational institutions to the plan. The 

 proposal has been so generally accepted

 success as secured.

 the American Association for the Advance-

 the week in which the first of January falls 

 as Convocation Week, to be set aside for 

 the meetings of national scientific and 

 learned societies. The Association of 

 Universities formally recommended by a 

 unanimous vote the adoption of this propo- 

 sition, and it has since been adopted by 

 nearly all the universities belonging to 

 that association. 



A report of the progress made was pub-
