Among the starved capsules the minimum number of seeds was 



• _^ _ _ 



maximum 168. One starved capsule contained only 20 seeds, and 

 was therefore not included ; one fed capsule was lost ; so that the 

 seeds of same number of capsules of each kind were counted. 



In calculating the average weight of a seed &c. in the following 

 Table the produce of only 20 fed capsules could be employed, as 

 the counted seeds of 9 fed capsules were thrown away before it oc- 

 curred to me to weigh them. 



It will be seen from the Tables that the difference between 

 the fed and starved plants was investigated in a variety of 

 ways, and that in every particular the fed show a marked
