THE DIGESTIBILITY OF THE DASHEEN. 7 



The variations which occurred in the results obtained in the two 

 sets of experiments were immaterial. Furthermore, the results of 

 the individual experiments agree quite closely with one another with 

 respect to the figures commonly reported for the carbohydrates. 



During these six tests the subjects ate on an average 40 grams of 

 protein, 128 grams of fat, and 229 grams of carbohydrates, which 

 were 79.9 per cent, 96.2 per cent, and 97.5 per cent digested, respec- 

 tively. These values indicate a very complete utilization of this 

 diet by the human body.
