On an average the daily diet supplied 18 grams protein, 68 grams 

 fat, and 281.8 grams carbohydrate, the energy value being 1,811 

 calories. 



Considering the digestibility of the ration as a whole on an average 

 the subjects digested 40.5 per cent of the protein, 71.8 per cent of 

 the fat, and 94.7 per cent of the carbohydrate. The estimated digesti- 

 bility of the oleo stearin alone is 80.1 per cent. The figure, as would 

 naturally be expected, is considerably lower than that of oleo oil,
