29 
chusetts was completed. The results of this survey as a contribu- 
tion to the War Effort in terms of specific information regarding 
medicinal plants will be published in the immediate future. 
My research this year involved a continuation of my investiga- 
tions to determine the physiological effects of the various substi- 
tute teas being used more widely during this current war period 
than under normal conditions. Several species of Rosa (Hips) 
and Rubus (leaves) were given special attention. During the 
Spring, the medicinal plants in the Botanic Garden were treated 
in a semi-popular fashion for publication in the July issue of the 
Garden Record. This work was organized by Dean C. W. 
Ballard of the College of Pharmacy, Columbia University, with 
the collaboration of the Resident Investigator (Econ. Plants) of 
the Brooklyn Botanic Garden; and Professor F. J. Pokorny of 
Columbia University.
