The ten Westerham-crossed plants here average 36.67 inches in height;
the ten intercrossed plants, 38.27 inches; and the ten self-fertilised,
23.31 inches. These three lots of plants were also weighed; the
Westerham-crossed plants weighed 28 ounces; the intercrossed plants, 41
ounces; and the self-fertilised, 14.75 ounces. We thus get the following
ratios:--

The Westerham-crossed plants in height to the self-fertilised as 100 to
63.
