fruits of exp. D were brought in for analysis between 3 P.M. Oct. 

 6 and 3 P.M. Oct. 7. The large series E furnished samples for 

 the chemical laboratory from Aug. 19 to Oct. 16. The two short 

 series were grown in large pots sunk in the ground, and furnished 

 abnormal fruits of the kind here considered from Sept. 10 to Oct. 

 6 (exp. A) and from Aug. 15 to Oct. 4 (exp. B). Thus, 

 three of these collections were made over a wide period, during 

 which the plants were subjected to great variations in meteor- 

 ological conditions. Furthermore, these repeated collections from 

 the same individuals must be composed of fruits representing the 

 plant in very different physiological stages. Sufficient proof of 

 this assertion is to be found in the demonstration that the Propor- 

 tion of teratological fruits becomes smaller in successive collec- 

 tions (Harris and Gortner, 19 14). 



This table by no means includes all of the fruits produced by 

 the plants. Others remained on the vines after the discontinuation 

 of collections for chemical purposes because of the lateness of the 

 season. Furthermore, large series of fruits were dissected and re- 

 corded for morphological purposes but omitted from the chemical 

 samples because not sufficiently mature.

With regard to this last point, the greatest care was taken to 

 secure fruits at as nearly the same stage of development as pos- 

 sible. In the gathering of the fruits only those with dried calyces
