re.si)cctively ; and the tough-poddedness seemed apparently to dominate over 
the soft-, but by measurement we could ascertain that the thickness of the 
scleren-chymatous tissue of the F-^ plant was intermediate, being 81 o., while 
in G- P- and M- P- it was 51 n and 100/^ respectively

In 1911. 
From the F-^ plants of the previous year, the following individuals were 
selected : — 
I X 1.2 VIII X 12. 1 
I X 1.3 Till X 12.4 
I X 1.4 VIII X 12.5 
4 X XVI.2 12 X VIII. I 
4 X XVI.4 13 X VIII.2 
4 X XVI.6 
30 seeds from each selected individual were sown on May 6, but, on account 
of the extraordinary dryness of the w^eather, uneven sprouting was caused 
(page 240). In Table 8, group A includes the offsprings which had for 
one of their parents an early pure line individual of G- P-, and group B? a 
late pure line individual of the same variety. Each of the groups A and B 
is differentiated into two sub-groups, according to the earliness or lateness of 
the sprouting. 
In 1912. 
As the sprouting of the F^ plants in 191 1 had been too uneven, we re- 
newed the raising in order to obtain the variation type in the F^ with nor- 
mal sprouting. For this purpose, we raised the progenies of the following 
F-L plants.
