WAXY ENDOSPERM IN HYBRIDS WITH SWEET CORN. Mii 
ments have been outlined for isolating and determining the nature 
of this new type. | 
Since all three classes of seeds occurred on the same self-pollinated 
ear, it was possible to compare the weights of the three classes where 
the parentage of all was identical. The horny, waxy, and sweet 
seeds from each of 49 ears were separately weighed. The result 
showed that in nearly every ear the horny seeds were heavier than 
the waxy, which were in turn heavier than the sweet. Specific- 
gravity determinations of the different classes showed no significant 
differences. The differences in weight must therefore be due to dif- 
ferences in size.
