THE INTERNATIONAL CONGRESS OF ARTS 

 AND SCIENCE. 



The widespread interest in the Inter- 

 national Congress of Arts and Science, to 

 be held at the St. Louis AA^orld 's Fair from 

 the nineteenth to the twenty-fourth of Sep- 

 tember, may justify a word concerning the 

 latest stages of its development. Science 

 has carefully sketched its beginning and its 

 growth. Full discussions characterized the 

 uniqueness of its plans and purpose and 

 the scientific aims which are so different 

 from the usual congresses with their dis- 

 connected programs and their lack of unity. 

 These papers showed that the congress was 

 to be controlled by the single purpose to 

 work towards the unity and inner relation 

 of knowledge; and that its program was a 

 complete whole whose parts were in closest 

 relation. The whole range of sciences is 

 embraced, while the entire field was divided 

 into twenty-four departments and these 

 into one hundred and thirty sections. The 

 addresses to be prepared by invited speak- 

 ers are to deal in all departments alike with 

 the inner unity and with the fundamental 

 conception and methods, and in all sections 

 alike with the interrelations to the neigh- 

 boring sections and with the leading prob-

 whole plan was followed in Science by re- 

 ports with regard to the actions of the or- 

 ganizing committee that, under the leader- 

 ship of Professor Newcomb, the president 

 of the congress, secured the cooperation of 

 leading specialists abroad. And, when at 

 the beginning of June the list of chairmen 

 and official speakers was completed and
