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 begit™ 
ners in physical chemistry and theoretical physics 
The second part presents the literature of the physio- 
logical réle 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 = a 
cise and forms an admirable addition to the ee
