 nearly alike as possible. 



This experiment was made October 23d, last, when the 

 cows were in the barn at hay, liaving two quarts of oat 

 meal each per day. 



The Ayrshii-e cow ^ave -22 pounds 4 ounces of milk ; 

 weight of cream 2 pounds ; time in churnino-, forty minutes ; 

 weight of butter, one pound one ounce ; weight of butter- 

 milk, rifteen ounces. Buttermilk appeared rich, as though 

 there were butter trlobulcs left in it. 



The Jersey heifer, two years old, gave 10 pounds 8 

 ounces of milk ; weight of cream, 1 pound 4 ounces. Time 

 of churning, twenty minutes ; weight of butter, 12 ounces ; 

 of butteruiilk, 8 ounces. This buttermilk was as blue as 

 skimmed milk. 



The next day I mixed the milk of the two cows, ^"eight 

 of milk, 32 pounds 4 ounces ; weight of cream, 3 pounds 1 

 ounce ; time of churning, thirty minutes ; weight of butter, 

 1 pound 12 ounces ; of buttermilk, 1 pound o ounces. 



"When taken separately, T had 33 pounds of milk, 3 

 pounds 4 ounces of cream, 1 pound 13 ounces of butter. 

 Mixed, I had 12 ounces less of nailk, and 1 ounce less of 

 butter. The time in churning the mixed was just half way 

 between the other two, so there seems to be no loss in this 

 experiment. Another experiment might result differently. 



The butter contained in o-lobules is lischter than milk. 

 The material of which the sack is composed, which contains 

 the butter, is heavier than the milk. This is proved by the 

 experiments of Dr. Sturtevant and others. Large globules, 

 containing more butter in proportion to weight of sack, rise
