 the average fruit that remains on the tree, as shown by the representative 

 data in table 38:

The number of seeds found in individual fruits that have fallen and in 

 individual fruits taken from the tree are given in table 39. The column 

 on the left contains the number of seeds to the fruit. The figures in the 

 other colirmns give the number of fruits showing the respective number 

 of seeds. It is seen that many attached fruits have relatively few seeds 

 and some drops have a high seed content. This suggests that other factors, 

 in addition to fertilization or pollination, are responsible for the set of fruit.
