"We thus find," he says, "as a result of corn breeding, 

 that in the seventh generation we have a maximum difference 

 of only 75 lb. of protein in the germs from 100 lbs. of low 

 protein and high protein corn, while in the endosperms from 

 these two kinds of corn we have a difference of 7 06 lbs. of 

 protein in 100 lbs. of corn. In other words, in changing the 

 protein-content of corn, the effect produced in the endosperms 

 amounts to almost ten times the effect produced in the germs."

602. The Proteids of Maize Grain, — Chittenden and 

 Osborne (2) find that the maize grain contains several dis- 

 tinct proteids, well characterized in reactions and composition. 

 Of these, there are three globulins, one or more albumins, and 

 an alcohol-soluble proteid known as zein. The quantities of 

 the different proteids in the maize grain are estimated {Hopkins, 

 4), as follows : —
