In these correlations between the plants of the same duplet or triplet, 
the coefficients for osmotic concentration are higher than those for 
specific electrical conductivity, or for the ratio of specific electrical con¬ 
ductivity to freezing-point depression. They are in practically every 
instance higher than those for hydrogen-ion concentration. Thus the 
concentration of total solutes seems to be more influenced by the environ¬ 
mental conditions than the concentration of all electrolytes or of the 
hydrogen-ion.
