remainder represents approximately tliat part of the dry matter 

 which is good for food. This latter is of two kinds, nitrogenous 

 and non-nitrogenous. The nitrogenous part consists mostly of 

 albuminoid matter, which is a very valuable form of food, but 

 there are also other nitrogenous compounds in the turnips which 

 are not valuable, and unless they are separated from the dry 

 matter before estimating the albuminoids, the feeding value of 

 the turnips is certain to be over estimated. This has been done 

 in the case of the quantities given below, so that they represent 

 the true albuminoid matter. The non-nitrogenous constituents 

 consists of oil, sugar, mucilage, digestible cellulose, and allied 

 compounds, and these also are valuable feeding substances. In 

 the following table the percentage and total product of these 

 substances are arranged : — 



<^The average percentage of albuminoid matter contained in 

 the [dry matter of the swedes is seen to be about 16 per cent.
