 own particular case. 



Btill fnrtlier, if we know, as we easily may, the propor- 

 tions of all)uniinoids and of amide-like bodies in the f<Td- 

 ing"Stnffs which we nse, we Iiavc, even with our probcut 

 limited knowledge of the subject, the basis for forming a 

 tolerably inteUigent judgment as to whether our ration is 

 deficient in true albuminoids or not. 



It is, of course, desirable that feeding standards should 

 distinguish between albuminoids and amides, and doubt- 

 less this wall be done to a large extent in future investiga- 

 tions. Meanwhile, the considerations here presented show 

 that those standards which we possess at present are far 

 from liaving lost their practical value when intelligently 

 used. 



Subjects not Considered. — Regarding;, as we do, the 

 determination of the proper feeding standards for the vari- 

 ous purposes of feeding as the chief object of all work in 

 this depai^tment of agricultural science, we nuist confine 

 ourselves in this part of the present work chiefly to the 

 consideration of these standards. It does not eomo within 

 the scope of this work to consider such questions as the 

 palatability of the various feeding-stuffs, the most suitable 

 kinds of fodder for different animals, or any ^' specific " or 

 <3ietetic action of particular fodders on the organism. 

 These are, in part, purely practical questions, and in part 

 questions to which science can as yet return no definite 

 answer. Consequently, though they are often of great 

 impoi^tanee, they do not properly find a place in g work 

 which treats of the application of science to feeding. 



Furthermore, it is not our purpose to consider tlie 

 necessary management and care of stock, the arrangement 

 of stalls, stables, and yards, or the various methods of
