EXPERIMENTS WITH RAW WHITE CORN MEAL. 
Three experiments were conducted with raw white corn meal. 
Analysis showed the composition of the corn meal to be: Water, 
10.54 per cent; protein, 8.88 per cent; fat, 4.24 per cent; carbo- 
hydrate, 75.04 per cent, including 1.67 per cent crude fiber; and 
ash, 1.3 per cent. 
The entire diet furnished the following average amounts of nutri- 
ents and energy per woman per day: Protein, 34 grams; fat, 68 
grams; carbohydrate, 242 grams; energy, 1,715 calories. The aver- 
age amount of corn meal eaten per woman per day was 158 grams 
and the carbohydrate supplied by the corn meal was 119 grams. 
The average coefficient of digestibility of the carbohydrate of the 
corn meal alone was 98.6 per cent. If allowance is made for 47 per 
cent undigested crude fiber, the resulting coefficient of digestibilit 
is 99.6 per cent. Microscopic examination showed absence of stare
