240 Non-I salable Races. 
At this point they were recorded and, if the first leaf 
was single, were usually pulled up. Those which were 
saved were usually weaker, more stunted and backward 
in growth. Several had not yet unfolded their first 
leaves, and amongst them a great number of the anom- 
alies were found when the examination was repeated a 
few days afterwards. 
I then convinced myself by a very simple experiment 
of the correctness of these conclusions. All that was 
necessary was to isolate the large and the small seeds in 
a sample and to sow them separately. But as there is 
no absolute limit between the two it was necessary to 
know how many seeds should be separated out, as the 
smallest. And this can only be done by the number of 
anomalies, i. e., compound primary leaves, they produce. 
I therefore selected a sample of seed whose capacity for 
producing anomalies I already knew. This was 15%; 
the sample was derived from a single seed-parent. I 
separated the seeds into three categories, small, inter- 
mediate and large. All in all there were 217 seeds of 
which 17 did not germinate. The characters of those 
which did are as follows: 
Number of divisions in the primary leaf. 
123 2-3 
Small seeds 31 9 16 12.5 % 
Intermediate seeds 50 2 1 1.5 % 
Large seeds 88 2 1 1.5% 
169 13 18 15.5 % 
It will be seen that almost all the abnormal seedlings 
are derived from the smallest seeds. The seedlings from 
the large seeds had, with a single exception which was an 
abnormal one, unfolded their primary leaves in May, and 
fourteen days after the seed had been sown ; the same
