tein. These 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 froni 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.
