glucose, and other corn products. It represents the germ 

 layer of the corn kernel from which part of the oil has 

 been extracted. Two methods are employed in the 

 separation of the germ from the kernel. In the manu- 

 facture of starch, the germ is usually removed by the use 

 of a weak water solution of sulfurous acid, while in the 

 making of hominy it is removed by mechanical processes. 

 Chemical analysis of the feeds in the first Indiana feed- 

 ing trial showed that the corn germ meals were consider- 

 ably richer in protein than corn, and further, that the 

 starch corn germ meal contained 6 per cent more protein 

 than the hominy corn germ meal. Judging from the 

 chemical analyses given in the following table, both feeds 

 contain suflBcient protein to dispense with the use of any 

 supplement.

Preliminary investigations by Skinner and Starr ^ at 

 the Indiana Experiment Station suggest the possibilities 

 in the use of corn germ meal as a substitute for corn. Two
