All the experimental evidence which has been adduced conspires ^o " 
so-called “ fattening ” of animals for the butcher, is propel y so esigiia . 
o-cSed “La” of animals are seen to contain as much, or more, of diy fatty 
substance, than of dry nitrogenous compounds. After the feeding or 
the percentage of the collective dry substance of the body was consideiably mciea-c . 
whibt fatty matter had accumulated in much larger proportion than the iiitiogcnous 
Irf pounds It is obvious, therefore, that in the increase itself of the fattening ammtd. 
the proportion of fat to the nitrogenous substance of growth, must e giea <■' . 
the total or standing live-weight of the animal. In other words, * “ 
the increase in weight of a fattening animal, must show a less 1'““" ^ the'whole 
substance, and a higher one both of fat and total dry substance, than that of the
