CHEMICAL ANALYSES. 



The blades of grass (including corn), clover, vetches, lucerne, etc., contain 

 more nitrogenous matter and less woody fibre than the stalks. 



The nitrogenous matter of plants, which, in its composition, 

 closely resembles that of the animal body, may be divided 

 into albuminoids (proteids) and amides. The albuminoids are 

 often called "muscle formers," but would be more correctly 

 termed " formers of nitrogenous tissue " ; because their pre- 

 sence in the food is necessary for the construction and repair 

 of every tissue which contains nitrogen. Although amides 

 also contain nitrogen, they are not capable of assisting in the 

 formation of nitrogenous tissue ; their office being to produce 

 energy and to manufacture fat. As the respective proportions 

 of albuminoids and amides vary a good deal in different 

 species of plants, the expression " nitrogenous matter " has
