"This table is. as regards water and ash, a repetition of last table, but includes the 

 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 nitrogenou* 

 and non-nitrogenous compounds, i. e. t albuminoids and carbohydrates, etc. It also 

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

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



t Organic matter here signifies the combustible part of the plant. 



i Carbohydrates, etc., includes fat, starch, sugar, pectin, etc., all la fart of Org. mottar 

 except albuminoids and crude fiber. 



i Crude fiber is impure cellulous. 



T Fat, etc., is the ether-extract, and contains besides fat, \rnv 4Uorphjrll, an,d in
