TEMPERATURE RANGE 16° TO l£° F. 
The (lata for the corn subjected to a temperature ranging 
from 16° to 1*2° F. are given in Table 7. It will be noted from 
this table that the fatality range is very much the same as 
for the temperature of 24° to 20° F., but runs somewhat lower. 
Samples containing 33 per cent or more of moisture were killed 
by the 24-hour exposure to this range of temperature; the 
embryo generally showed a dark color, and ice formation was
