Ear No. 1129 had 24.1 per cent of waxy seeds, a close approxima- 
tion to the expected 25 per cent, the deviation being less than the 
probable error. The deviation of ear No. 1130 was 3.7 times the 
probable error below 25 per cent. The plant that served as the male 
parent of ear No. 1180 bore ear No. 1185, the result of self-pollina- 
tion. The deviation of this ear was also below the expected 25 
per cent by three times the probable error. This fact would indi- 
cate that the low percentage of waxy seeds observed on ear No. 1130 
was due to the male parent, since there was also a deficiency of waxy 
seeds when the male parent was self-pollinated.

If any difference in the behavior of the progenies of Nos. 1129 and 
1130 occurred, a lower percentage of waxy seeds on the progeny of 
ear No. 1130 would be expected. A careful analysis of the progeny 
with this point in mind failed to reveal any significant differences, so 
that the differences observed in the percentage of waxy seeds of the 
two ears, Nos. 1129 and 1130, must, for the present, be ascribed to
