SCIENCE. 



[N. S. Vol. XXIV. No. 601. 



Stanley McCormick and Professor C.-E. A. 

 Winslow made brief addresses expressing the 

 regard and affection of the former students 

 of the department for its head. 



The evening closed with a speech by Pro- 

 fessor Sedgwick himself in which he expressed 

 his appreciation of the occasion, and spoke of 

 his connection with the great university at 

 Baltimore and the great technical school in 

 Boston, and of the duty which now rests upon 

 the biological department of the institute, to 

 train men for the conduct of the sanitary 

 reforms which are spreading so rapidly all 

 over the union. 



The chief event of the occasion was the 

 presentation of a volume of biological studies, 

 ' dedicated by his pupils to William Thompson 

 Sedgwick, to express their regard and admira- 

 tion for him as a friend, teacher, investigator 

 and public-spirited citizen, and also to affirm 

 their loyalty to the ideals for which he has 

 always stood.' The volume, which has been 

 prepared in secret and was a complete surprise 

 to its recipient, has been published at the 

 University of Chicago press under the editor- 

 ship of Professor E, O. Jordan. It contains 

 nineteen original contributions to biology and 

 sanitary science, the authors and titles being
