weights were from twenty-two to twenty-six pounds in case 

 of different animals. The same fodder articles were used as 

 in the third, fourth, fifth and sixth experiments ; they were, 

 however, fed in different proportions. The daily ration of 

 corn meal was gradually increased during the progress of 

 the experiment, for the purpose of altering the relative pro- 

 portion between the nitrogenous and non-nitrogenous matter 

 in the feed. The relative proportion of one part of digestible 

 nitrogenous matter to two and nine-tenths parts of digestible 

 non-nitrogenous matter was changed at stated periods until 

 it reached 1 : 4.28 ; practically, three feeding periods.
