As has been stated the hog that was slaughtered before feeding was 

 evidently in slightlj^ better condition. We may be fairly certain that 

 the one slaughtered before feeding, or No. i , was at least not richer in 

 nitrogenous matters than the one fed, or No. 2. We will therefore as- 

 sume that the two hogs were of the same composition at the time the 

 first one was slaughtered. On this assumption the composition be- 

 fore and after feeding of the hog fed, and the gain or loss of the va- 

 rious constituents, are shown in the following table :

The table shows a marked increase of the nitrogenous matter 

 over the fat and a considerable falling off of water as a result of 

 the feeding. This experiment was in every sen.se preliminary and 

 ofcour.se the data are insufficient to furnish positive proof as to the 

 questions asked, still all the indications are that a mature animal 

 can be readily made to increase in muscle or lean flesh. This is 

 apparent to the eye in comparing the photo-engravings of .sections 

 of the hog No. 2 and sections of hogs of about the same weight, 

 fattened in the ordinary manner, as found in the Ithaca markets. 



The upper .section in each plate is from hog No. 2, the middle and 

 lower sections are from carcasses .selected in the Ithaca market ; 

 both of them of about the same weight as our hog No 2, and both 

 considerably younger. They were fattened by fanners in the neigh- 

 borhood, in the usual wav, largely on corn. The reader will notice 

 the remarkable proportion of lean to fat in the carcass of hog No. 2. 



We had carried on an entirely parallel experiment with mature 

 grade Merino ewes, except that fin additional lot was added that 

 were fed a strongly carbonaceous ration ; unfortunately an ac- 

 cident occurred during the rendering of the carca.sses and all com- 

 parative results by analysis were lost. In .so far as the results 

 could be judged by the eye they, were in accordance with tho.se 

 obtained from the carcass of the hog. I. P. ROBERTS.
