to 95. We thus see that the self-fertilised children of Hero certainly
inherit the powers of growth of their parents; for they greatly exceed
in height the self-fertilised offspring of the other self-fertilised
plants, and even exceed by a trifle the intercrossed plants,--all of the
corresponding generation.

Several flowers on the self-fertilised children of Hero in Table 2/14
were fertilised with pollen from the same flower; and from the seeds
thus produced, self-fertilised plants of the eighth generation
(grandchildren of Hero) were raised. Several other flowers on the same
plants were crossed with pollen from the other children of Hero. The
seedlings raised from this cross may be considered as the offspring of
the union of brothers and sisters. The result of the competition between
these two sets of seedlings (namely self-fertilised and the offspring of
brothers and sisters) is given in Table 2/16.
