Heights of Plants in inches:

Column 1: Number (Name) of Pot.

Column 2: Crossed Plants.

Column 3: Self-fertilised Plants.

Pot 3 : 78 4/8 : 73 4/8.
Pot 3 : 77 4/8 : 53.
Pot 3 : 73 : 61 4/8.
Pot 3 : 77 4/8 : 75 4/8.

Total : 306.5 : 263.5.

Crossed and self-fertilised seeds of the third generation were also sown
out of doors late in the summer, and therefore under unfavourable
conditions, and a single stick was given to each lot of plants to twine
up. The two lots were sufficiently separate so as not to interfere with
each other's growth, and the ground was clear of weeds. As soon as they
were killed by the first frost (and there was no difference in their
hardiness), the two tallest crossed plants were found to be 24.5 and
22.5 inches, whilst the two tallest self-fertilised plants were only 15
and 12.5 inches in height, or as 100 to 59.

I likewise sowed at the same time two lots of the same seeds in a part
of the garden which was shady and covered with weeds. The crossed
seedlings from the first looked the most healthy, but they twined up a
stick only to a height of 7 1/4 inches; whilst the self-fertilised were
not able to twine at all; and the tallest of them was only 3 1/2 inches
