These data show that after twenty-four hours the leaves on the 

 shoo't with orange attached contained an average of 52.3% more water 

 than those on the other shoot. They further show that the detached 

 fruit contained 42.9% more water than the attached fruit from which 

 the leaves had been drawing their supply. This is considered to be 

 conclusive evidence that in the case of excised branches the leaves 

 can draw water from the fruit. 



Experiment 3 Two shoots in every respect similar to those used 

 in the previous experiments were treated in the same manner as those 

 of Experiment 1 and 2. These were then weighed at irregular inter- 

 vals until they had reached a constant weight. During the interim 

 they were kept on the laboratory table. The data obtained are found 

 summarized in table 3 :
