From the upper part. 



Combining' the above two results."^ 



From these results we see a clear difference between the 

 mean weights of the upper and lower parts, while we cannot 

 find any difference between the numbers of their vesicles. It 

 may be here remarked that the difference of weight came from 

 the fact that most of the fruit of the upper branches was 

 situated on main branches, while those of lower branches were 

 on the small lateral branches, and hence the former received a 

 richer flow of nourishment than the latter. 



On 15th Nov. 1909 I obtained the following data from 

 another, but somewhat smaller tree in the same place as A.

This result shows us that the age of a tree has not any 

 influence upon the variation of its vesicles. 



On 12th 1910 the following data were obtained from the 

 large tree of 1909. 



1) The mean was obtained from the weighing of 947 fruits. 



2) V number of vesicles.
