ASH CONSTITUENTS IN ANIMAL PRODUCE, AND VOIDED 

 FOR 100 CONSUMED AS FOOD. 



The proportion of the ash constituents and nitrogen

* The quantities of nitrogen given in this column are a little below 

 the truth, as, besides the undigested albuminoids, some nitrogenous 

 biliary matter is present in the solid excrment. With oxen and sheep 

 the amount of biliary matter in the excrement is very small ; with pigs 

 it is more considerable. In the case of the pig the nitrogen in the 

 solid excrement should probably stand as 26'0, and that in the liquid 

 as 59-3.
