The meal was finer than necessary to pass thru the sieve. The meal had the following composition: Per cent Moisture 8.23 Ash 4.60 Fat 18.01 Protein 40.99 Crude fiber _ 1.70 Nitrogen-free extract 26.47 The bran had the following composition: Per cent Moisture 8.46 Ash, 4.42 Fat 1.50 Protein, 5.81 Crude fiber 37.00 N-free extract 42.81 Digestibility of the Bran In the digestibility experiment, the subject was a man thirty-eight years old, weighing 150 pounds, 5 ft. 8 inches high, enjoying good health and working at the ordinary laboratory routine.

The stools were each treated as in previous experiments, and weighed when air dry 60 grams. The analyses were carried out as in previous experiments. The composition was as follows: Per cent Moisture 7.31 Ash 22.23 Fat 24.11 Protein 12.40 Crude fiber 20.30 N-free Extract 13.65 Since the amount of protein and fat in the bran amount to so little in each case, we...
