For Students of Botany 
Physics and Chemistry 
The Role of Diffusion and Osmotic 
Pressure in Plants 
By Burton E. LIVINGSTON 
HE first part deals with a clear statement of the 
physical principles of diffusion and osmotic 
pressure, and will probably be found of use to begin- 
ners in physical chemistry and theoretical physics. 
The second part presents the literature of the physio- 
logical rdle of these factors in a connected and reada- 
ble form, and embodies the researches of the author 
as to the influence of the medium. 
“The treatment of the whole subject is clear and con- 
cise and forms an admirable addition to the literature of 
physiological botany. It will be found indispensable to all 
students along these lines.’”— 7he Plant World.
