In studying those results it will be noted that the amount of ash 

 ami tiher extract in the corn hulls is decidedly lower than that in the 

 brail of kalir, milo, or feterita. These determinations in the kafir, 

 milo. and feterita appear t<> resemble one another fairly closely.

The most noticeable differences among these results are in the 

 comparatively high fat content of the corn and the comparatively 

 high protein content of feterita.

These results show a marked similarity, the protein content being 

 slightly higher in the kafir than in the other grains.

In Table 8 notice is immediately taken of the low ether extract of 

 the milo germ. The other results show a great similarity. 



A general consideration of all the tables shows that the protein 

 content of the feterita is higher than that of the other grains. The 

 horny endosperm in each case has more protein than the starchy 

 endosperm. The germs of these sorghums are very similar in com- 

 position.
