COMPOSITION OF CORN MEAL.

tein. Those results show the value of this offal for feeding, but the 
high acidity is significant proof of its unsuitability for human food. 
WHOLE-KERNEL STONE-GROUND MEAL. 
The samples without exception were from southern mills. Analy- 
ses of both the meal and the corn from which it was milled appear in 
Table 2. As the corn was ground without the removal of any constit- 
uent other than some of the thin, papery chaff or "bee wing," the 
meal when ground should not differ materially from the corn in com- 
position, except for a possible change in moisture content. Whether 
or not the moisture is less or greater than in the corn depends on the 
dryness of the latter and on the climate. Ordinarily there is a loss 
in grinding.

was milled.
