SIZE OF MILK GLOBULES. 381 



Experiment "VI. 

 Three cows of the same herd, and under the same treat- 

 ment. Xhe trial was made Avith milk of the same milking, 

 treated alike : — 



Days from Average size 



calving. of globule. 



No. 1, 15 4440'' 



2, 27 5260" 



3, 40 5520''

Butter to Milk. 



No. 1. Pasture and | quart oil-meal, 



about 2 to 3 quarts shorts, . =1 lb. : 23.23 lbs. 



2. Pasture and 3 quarts oil-meal, 3 



quarts shorts, 1 quart oats, . =:1 lb. : 23.27 lbs. 



3. Pasture and ^ quart oil-meal, 



about 2 to 3 quarts shorts, . =1 lb. : 17.77 lbs. 



Experiment VII. 

 Milk of different cows, bu: the same breed. Measurements 

 taken at different times, and under varying conditions of 

 food, etc. The sequences are not thereupon as regular as in 

 the experiments V. and VI : — 



Days from calving, 11 



I have also reason to believe that the size of these globules 

 is varied by the feed and condition of the cow, and that
