the amounts of digestible nutrients in any of the foods 

 there recorded. For the convenience of the ftudenl WB 

 have calculated the amounts of digestible nutrients in 

 most of the foods shown in Table V, and the result! 

 are arranged in Table VII. The nitrogen-free extract 

 and crude fiber are combined in this tabic, and the 

 mum is given under carbohydrates.

 is digestible?
