was furnished by corn meal, and 10. i per cent by peanut meal. 
Loughlin (j) have shown that normal growth can be secured.^ In our 
experiments normal growth was obtained with mixtures consisting of 75 
parts of com meal and 25 parts of peanut flour at a protein level of 15.5 
per cent. From such a protein mixture two-thirds of the protein was
