1 Total loss in weight of acid in 100 berries: Catawba, 2.45 grams; Concord (Sandusky), 2.15 grams; Con- 

 cord (Charlottesville), 3.03 grams. 



2 Data not complete. 



ANALYTICAL RESULTS ON THE WHOLE FRUIT SAMPLES. 



The data on the examinations made of whole-fruit samples are 

 given in Table 6. These figures are necessarily percentages of the 

 weighed fruit sample. Therefore, for the purpose of comparison, 

 the results for sugar and acid of the juice samples given in Table 1 

 are calculated to percentages and these data for both juice and whole 

 fruit samples are brought together in Table 7.
