 taining 1.45 pounds of digestible protein, .54 pound of 

 digestible fat and 11.44 pounds of digestible carbohydrates,

 9.96 pounds of digestible carbohydrates, a slight increase in 

 the total nitrogenous matter.

 the figures as the results of two careful h- conducted experi- 

 ments along this line of investigation.
