Table 104. Table D.

 Relative fertility of the offspring from crossed & self-fertilised  plants, of the first or succeeding generation, all  being spontaneously naturally fertilised & therefore in like manner,  as judged by the number of the fruit, or by the average number of the seeds per fruit, or by both data combined.

The fertility of the crossed plants being as base taken as 100.
