STUDIES ON FRUIT RESPIRATION. 



experiments 1 and 2, no acceleration in rate of respiration is shown. 

 At the conclusion of the experiment a very slight leak was detectable 

 in each of the systems, but it was probably not sufficiently large to 

 affect the results. 



The results, therefore, show that if any change in the rate of 

 respiration of peaches is caused by picking, such change is very small 

 and not measurable by the method employed.

1 The jar cracked during the run. Higher result possibly due to contamination by outside air. 



2 A very slight leak perceptible. 



3 A barely detectable 'eak found in both systems.
