The Westerham-crossed plants in weight to the self-fertilised as 100 to

The Westerham-crossed plants in weight to the intercrossed as 100 to
101.

The intercrossed plants in weight to the self-fertilised as 100 to 22.3.

We here see, judging by weight instead of as before by height, that the
Westerham-crossed and the intercrossed have an immense advantage over
the self-fertilised. The Westerham-crossed are inferior to the
intercrossed by a mere trifle; but it is almost certain that if they had
been allowed to go on growing for another month, the former would have
completely beaten the latter.

As I had an abundance of seeds of the same three lots, from which the
foregoing plants had been raised, these were sown in three long parallel
and adjoining rows in the open ground, so as to ascertain whether under
these circumstances the results would be nearly the same as before. Late
in the autumn (November 13) the ten tallest plants were carefully
selected out of each row, and their heights measured, with the following
result:--
