 newer analyses of 1865-7. Therefore the averages of water and ash do not in all cases 

 agree with those of the former tables. It gives besides, the proportions of nitrogenous 

 and non-nitrogenous compounds, i. e., albuminoids and carbohydrates, etc. It ate* 

 states the averages of crude fibre and of fat, etc. The discussion of the data of this 

 table belongs to the subjects of Food and Cattle-Feeding.
