Chemical Detenninations. 

 The work here reported is based iu eonsiderable degree on 

 chemical work done in the hiboratury of the college. During 

 the past two years over 150 samples of apjjles have been snb- 

 j exited to partial analysis, the results of which, so far as they 

 are deemed worthy of i)ublication, 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 

 various varieties grown in the different localities. The samples 

 received varied from a half dozen to a barrel, and from these 

 from six to tweh'c good sjiecimens were selected for analysis. 

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

 ple for sugar determinations, were preserved in a glass jar with 

 formaldehyde. The methods of analysis followed were those of 

 Ijiillelins on and 107 of the Ijureau of Chemistry. 



The determination of total solids was made l)y drying 2.5 

 grains on ituinicr' in n wnter o\-ou at 05^ to 08° for twenty
