RESEARCH IN BIOLOGICAL CHEMISTRY 



Biochemical research may be conducted, by advanced workers, independently 

 or under guidance, in any of the departmental laboratories. 



LABORATORIES FOR ADVANCED WORK IN BIOCHEMISTRY 



The laboratories in which the advanced work of the biochemical department 

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

 College, New York Botanical Garden and Bellevue Hospital. Each laboratory 

 is well equipped for research in nutrition and all other phases of biological 

 chemistry. 



BIOCHEAIICAL LIBRARY 



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

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

 raent, to all past and present workers in the Department. The library contains
