From the data recorded in these tables it may be calculated that an 

 average of 237 gm. of meat, furnishing 78 gm. of protein, or 75 per cent 

 of the total protein of the diet, was eaten daily. The five subjects com- 

 pleted the experiments in good condition and without having experienced 

 any physiological disturbances. The average values of seven experi, 

 ments for the digestibility of total protein and that of meat protein alone 

 are practically identical, being for the former 92.9 per cent and for the 

 latter 92.7 per cent. The values estimated for the digestibility of bob- 

 veal protein in the different experiments are not consistently higher or 

 lower than the determined values for the protein of the total diet. This 

 irregularity is very likely due to the variation in the amounts of protein 

 obtained from the different sources. 



CHECK EXPERIMENTS 



Tests of the digestibility of market veal, using the same basal ration 

 and with the same subjects and method of cooking as for bob veal, 

 were made in order to compare the digestibility of very young and 

 market veal under identical conditions. For this purpose legs of veal 

 from animals at least 4 weeks old were purchased in the open market. 

 Although it was realized that market veal contained a larger percentage
