practically the same, wherever this work is carried out intel- 

 ligently. The results obtained are, therefore, applicable 

 for the determining of a comparative value wherever the 

 identity of the material can be established. 



The actual results of the analysis are usually reported 

 under the following headings : — 



1. Amount of moisture lost at 110° C, or 230° F., and 

 amount of dry matter left behind. 



2. Amount of mineral matter left behind after a careful 

 incineration of the material. 



3. Amount of organic nitrogenous matter, commonly 

 called crude protein. 



4. Amount of non-nitrogenous organic matter, exclusive 

 of fat and of coarse cellulose substances. 



The entire mass which any fodder substance leaves behind 

 after being heated at one hundred and ten degrees, Centi- 

 grade thermometer, is called dry matter. An increase in 

 dry substance in case of any plant or part of plant at the 

 same stage of growth indicates usually a higher feeding, 

 value. To satisfy the cravings of the animal, a certain 

 quantity or bulk of coarse, dry matter becomes an impor- 

 tant consideration in making up the fodder rations for differ- 

 ent classes of animals. In raising young stock for fattening 

 purposes, a liberal supply is also desirable, to effect a 

 proper distension of the digestive organs, to make them 

 good feeders hereafter. 



Nitrogenous substances, or protein matter, refer to several 

 groups of nitrogen-containing compounds, of plants in par- 

 ticular, as albumin, fibrin, legumin, basein, etc., which are 

 essential for the formation of blood and tissues. Those 

 contained in animal matter, as meat refuse, are frequently 

 considered of a higher value than those in many plants. 



Non-nitrogenous substances include, in particular, starch, 

 sugars, organic acids, gums, fats and the digestible portion 

 of the cellular matter of the fodder. These substances are 

 readily transformed within the digestive organs into soluble 

 compounds of a similar chemical character, and are thus 

 assumed to serve an identical physiological purpose. As 

 more recent investigations have shown a superior physio-
