this it doubtless happened that in some cases a larger percentage 
of relatively green apples was obtained than in others. In addition to 
this, the chemical composition. of the apples changes very rapidly 
after they are picked from the trees. 
This is a matter which was not

is fully as it might have been. 
Owing to the fact that the apples were grown in West Virginia, from 
twenty-four to thirty-six hours elapsed from the time they were picked 
until analysis was begun in the laboratory. It was supposed that this 
lapse of time would not cause great changes in the composition of the
