AN EXTENSION TO 5.99° OF TABLES TO DETERMINE 
THE OSMOTIC PRESSURE OF EXPRESSED VEGE- 
TABLE SAPS FROM THE DEPRESSION OF 
THE FREEZING POINT 
J. Arthur Harris 
Some months ago Dr. Gortner and I published in this journal 
(Amer. Journ. Bot. i: 73-75, Feb. 1914) tables of the value of 
P = I2.060A — .02lA2 
for freezing point lowerings of .01° to 2.99°. 
At that time this range of values seemed to us, as well as to others, 
Hundredths of Degrees, Centigrade
