LiN.S. Vol. XXVI. No. 677 



by the congress for seeing the great paleonto- 

 logical collections of the Eastern United States 

 and to the further opportunity which the meet- 

 ing of American with European paleontologists 

 would afford for the discussion of some of the 

 broader problems of the science. The response 

 to the invitation was a gratifying one; such a 

 goodly number of paleontologists attended the 

 congress, and so much was the need of such a 

 periodic gathering of the workers in this sci- 

 ence felt, that the permanency of the section 

 is assured. These meetings will be looked 

 forward to as the opportunity for establishing 

 closer personal relations with fellow paleontol- 

 ogists of distant lands and for a discussion of 

 those questions of our science which are of 

 more than local interest. 



The meetings of the section were scheduled 

 for Tuesday and Wednesday mornings, August 

 20 and 21, from 10 a.m. to 1 p.m., but it was 

 found necessary to hold additional sessions on 

 Thursday and Friday mornings. The first 

 meeting was called to order by the organiza- 

 tion chairman, Professor H. F. Osborn. Pro- 

 fessor Charles Deperet, of the University of 

 Lyons, France, was elected first chairman of 

 the section, and Professor A. W. Grabau, of 

 Columbia University, New York, secretary. 

 Professor Gustav Steinmann, of the University 

 of Bonn, was elected chairman for the sessions 

 of Thursday and Friday. 



The principal address of the meeting was 

 delivered by Professor C. Deperet, on Wednes- 

 day morning. It was given in French, the 

 title being " Les migrations des f aunes ter- 

 tiaires entre I'Europe et I'Amerique." Two 

 other addresses on the broader aspects of the 

 science were made, one by Professor Gustav 

 Steinmann in German, on " Die Bedeutung 

 der Palaontologie fiir die Abstammungslehre," 

 on Wednesday, and the other on Friday, by 

 Professor H. "F. Osborn, on " Evolution as it 

 appears to the Paleontologist."
