SCIENCE. 



'Si: 



The principal topics for discussiou at the 

 conference of delegates will probably include 

 the following subjects: (1) Plans for coopera- 

 tion in solar research, and the preparation of 

 a general program of observations ; (2) forma- 

 tion of an international committee to conduct 

 this work; (3) adoption of a system of stand- 

 ard wave-lengths. 



INVITATION TO THE INTERNATIONAL CON- 

 GUESS OF ARTS AND SCIENCE. 



The organizers of the congress, to be held 

 at the universal exposition, St. Louis, on Sep- 

 tember 19-25, 1904, desire to invite the special 

 attention of professors and men of science in 

 the United States and Canada to the unex- 

 ampled opportunity which it offers to meet 

 and hear a great number of eminent men of 

 learning. It is expected that more than three 

 hundred eminent scholars of Europe and 

 America will deliver discourses in the various 

 departments and sections of the congress, and 

 that several hundred shorter communications 

 will be made by those present. 



It is the desire of the directors of the fair 

 and of all concerned in the organization that 

 professors and instructors in our colleges and 

 universities, and members of the learned pro- 

 fessions generally, shall, so far as possible, do 

 honor to our distinguished visitors by attend- 

 ing the congress. For this no fee is charged 

 and no formality is necessary except enrol- 

 ment on arrival. It is, however, desirable to 

 apprise Mr. Howard J. Rogers, director of 

 congresses. Universal Exposition, St. Louis, 

 Mo., in advance, what departments of the eon- 

 g-ress one desires to attend. A program of 

 its proceedings, with such other instructions 

 as may be necessary, will be sent by Mr. 

 Rogers on application.
