RESEARCH IN BIOLOGICAL CHEMISTRY 

 Biochemical research may be conducted, by advanced workers, independently 

 or under guidance. Prof. Gies consults regularly with investigators in the 

 laboratories of Botany and Zoology on Tuesday afternoons, and at the N. Y. 

 Botanical Garden on Wednesday afternoons. 



BlOCHEMICAL LIBRARY 

 Prof. Gies' library occupies a room adjoining the main biochemical labora- 

 tory at the College of Physicians and Surgeons and is accessible, by appoint- 

 ment, to all workers in the Department. 



LABORATORIES FOR ADVANCED WORK IN BIOLOGICAL 



CHEMISTRY 



The laboratories in which the advanced work of the biochemical department 



is conducted are situated at the College of Physicians and Surgeons, Teachers 



College and the New York Botanical Garden. The laboratories are well 



equipped for research in nutrition and all other phases of biological chemistry. 



COLUMBIA UNIVERSITY BIOCHEMICAL ASSOaATION 

 The Biochemical Association holds quarterly scientific meetings, which are 

 open to all students in the University. 



SUMMER SCHOOL COURSES 

 Summer Session courses are mentioned in the foregoing references to 

 Courses 101-102 and 104. Prof. Gies will have charge of both courses next 

 Summer. He will also conduct a special lecture course in nutrition. The labora- 

 tories will be open for research during the summer session.
