nutrients being in all eases quite thoroughly digested and about 03 

 per cent of the energy of the diet being available. Considered as a 

 whole the results agree quite closely with the average values obtained 

 in a large number of American experiments made under widely vary- 

 ing circumstances. As has been observed in other experiments, when 

 corrections for metabolic products, obtained by the pepsin method, 

 are introduced the coefficients of digestibility of protein are higlier 

 than when the corrections are obtained by the ether, alcohol, and 

 limewater method. 



During the digestion experiments it was found that animal foods 

 furnished from about 33 to 50 per cent of the protein and from about 

 20 to nearly 50 per cent of the energy of the diet. Baked beans fur- 

 nished from 20 to 33 per cent of the total protein and from 10 to l-t 

 per cent of the total energy of the diet.
