This milk evidently presents a larger quantity of butter than ap- 

 pears in any of the preceding analyses. But no hasty conclusion 

 must be drawn from th's : for the succeeding experiments will ex- 

 hibit a change equally sudden in the proportion of the fatty element, 

 but in a difterent way. 



In a second series of experiments I set myself the task of ascer- 

 taining whether green fodder had any such remarkable influence on 

 the production of milk, and especially of its fatty element, or butter.

The ration here consisted of winter fodder :
