CONVOCATION WEEK. 

 The second of the eonvoeation week 

 meetings of scientific and learned societies 

 leaves no doubt as to the wisdom of the 

 general plan, though it is evident that a 

 final solution can only be reached by grad- 

 ual evolution. The meetings held at St. 

 Louis, Philadelphia, Pittsburg, Princeton 

 and elsewhere brought together large 

 groups of scientific men, and the programs 

 of papers and other features, both formal 

 and informal, were satisfactory and profit- 

 able. With the exception of the first of 

 the convocation week meetings held last 

 winter at Washington, when practically all 

 the scientific societies met together, so 

 many scientific men have not simulta- 

 neously attended the meetings of their so- 

 cieties. Last winter there was some fric- 

 tion in the relations of the numerous so- 

 cieties meeting together for the first time 

 and partly confluent in their scope; but 

 such friction naturally leads to attrition 

 and adjustment. When individuals or so- 

 cieties are isolated there are always excres- 

 cences in process of formation, which re- 

 quire friction for their removal. 



We can not, consequently, regard the 

 meetings this year as wholly satisfactory. 

 The attendance of the meeting of the 

 American Association and its affiliated so- 

 cieties at St. Louis was not as large as had 

 been expected. It seems unfortunate that
