The twenty-fourth session of the Biological 

 Laboratory of the Brooklyn Institute of Arts 

 and Sciences located at Cold Spring Harbor, 

 New York, will be held during six weeks, be-

 A course in bird study will be given by Mrs. 

 Alice Hall Walter, and by Dr. C. E. Ehinger, 

 of the Pennsylvania State Normal School. 

 Comparative anatomy, by Professor Henry S. 

 Pratt, of Haverford College, and Dr. David 

 D. Whitney, of Wesleyan University. Animal 

 bionomics and evolution by Dr. Davenport. 

 Cryptogamic botany by Dr. Harlan H. York, 

 of Brown University, and Dr. W. E. Maneval, 

 of Randolph-Macon College. Plant geography 

 and ecology, by Professor John W. Harsh- 

 berger, of the University of Pennsylvania. 

 Those who wish to carry on investigation at 

 the laboratory are invited to correspond with 

 one of the above-named instructors. As in the 

 preceding three years a training course for 

 field workers in eugenics, strictly limited in

A STATION for instruction and research in 

 biology will be maintained by the University 

 of Michigan, for the fifth season, as a part of 

 its regular summer session, during the eight 

 weeks from July 1 to August 22. The station 

 is located near the Bogardus Engineering 

 Camp of the university on a tract of about

 and stretching from Douglas Lake to Burt 

 Lake in Cheboygan County, Michigan, 17 

 miles south of the Straits of Mackinac. The
