EXPERIMENTS WITH RAW GRAHAM FLOUR. 
Three experiments were conducted with raw graham flour made 
up in the form of frozen pudding, the proportion of flour used being 
the same as in the case of the pure cereal starches. The graham 
flour was found by analysis to contain 11.82 per cent water; 10.63 
per cent protein; 1.71 per cent fat; 74.12 per cent carbohydrate, 
including 2.25 per cent crude fiber; and 1.72 per cent ash. 
The entire diet furnished the following average amounts of nu- 
trients and energy per woman per day: Protein, 40 grams; fat, 83 
grams; carbohydrate, 295 grams; energy, 2,085 calories. The aver- 
age amount of raw graham flour eaten per woman per day was 196 
grams and the average amount of carbohydrate supplied by the flour 
alone was 145 grams per woman per day.
