i:; 



fact must certainly largely account for the superior digestibility of 

 the former. Several examinations of the feces in these experi- 

 ments have failed to show the presence of sugars or starch, the 

 diastase test being employed for the latter. These carbohydrates 

 being entirely soluble in the digestive fluids, as it was reasonable 

 to expect, their presence in these foods in greatly varying quan- 

 tities must certainly cause corresponding variations in the digesti- 

 bility of the nitrogen-free-extract, and consequently of the total 

 dry matter, other things being equal. 



That this is so, is easily seen from the figures presented in Table 



xxn.
