One surprising result noticed was that Indian corn (Table 14), 

 made 100 per cent of germination in five days where dry seeds had 

 been frozen for twenty-four hours, while similar dry seeds, not frozen, 

 made only 68 per cent germination. Just why freezing should appar- 

 ently have been beneficial to germination is not clear. Seeds that

 made 100 per cent germination, while only 80 per cent grew where 

 similarly frozen and soaked but not etherized. Others that had the 

 same preliminary treatment but etherized for only twelve hours, 

 showed 98 per cent of germination. Thus it would seem that the 

 ether treatment increased the amount of germination, and a study
