The differences between Lots III and IV in proportion to the 

 live weight, in the dressed weight, wool, and some of the more im- 

 portant internal organs is shown in the following statement. 



The following parts and organs were greater in the lambs fed 

 on nitrogeneous food by the following percentages in proportion to 

 the live weight : 



Wool, . . . .44 per cent. Heart, ... 40 per cent. 



Kidneys, . . 18 " Liver, .... 13 " 



Blood, ... 19 " Lungs, ... 18 " 



The following were greater in the lambs fed on carbonaceous 

 food : 



Dressed Weight, 13 per cent. 



Caul Fat, 242 " 



Kidney Fat, 198 



In the experiment of 1888 the organs greatest in the animals fed 

 nitrogenous food, were : 



Dressed Weight, . . 9 per cent. Caul Fat, 13 per cent. 



Wool 26 " Kidneys, 13 " 



And those that were greatest in the animals fed carbonaceous 

 food, were : 



Heart, ... 26 per cent. Liver, .... 4 per cent. 



Blood, ... 9 " Lungs, ... 8 



SUMMARY. 



The weight of evidence of all of our experiments, together with 

 results obtained by other experimenters in the same field, seems 

 to show : 



That corn, as an exclusive grain ration, does not give the best 

 results, either in amount, quality or economy of production, when 

 fed to growing or fattening animals. 



That the amount of water drank (especially in the case of our 

 lambs) is a pretty certain indication of the rate of gain. 



That the production of wool- is very greatly dependent upon the 

 nitrogen in the ration.
