Cheinical Dcterininations. 

 The work here reported is based in considerable degree on 

 cbeniical work done in the laboratory of the college. During 

 the past two years over 150 samples of apples have been sub- 

 jected to partial analysis, the results of which^ so far as they 

 are deemed worthy of publication, are presented in Table 7. 

 The names and locations of the growers are as follows: — 



As a rule the samples represent about the best type of the

 from six to twelve good specimens were selected for analysis. 

 They were ground in a food chopper, and after weighing a sam-

The determination of total solids was made by drying 2r) 

 grams on pumico iu n wntor oven at 05° to 98° for twenty
