178 TESTIMONY OF EGBERT OGDEN DOBEMUS. 



milk, one from an Alderney cow and one from a native cow ; these 

 milks were mixed, and the gravity at 60 Fahr. was 95 ; I may men- 

 tion incidentally at 75 Fahr., when it was first tested, it stood at 91 ; 

 at another place nearer Mr. Mulford's, called Uncle Kichard's, I 

 obtained milk from a cow which at a temperature of 93, just as it 

 was drawn, of course this is not blood heat, stood 85 on the lacto- 

 meter, the same lactometer being always used, at 79 as it gradually 

 cooled it stood at 100 ; at 60 it stood at 110 ; in the same place 

 another cow, Indiana, at 95 Fahr., it stood at 90 ; the gravity when 

 cooled to 60 it stood at 112 ; another cow, the belt cow, one of those 

 peculiar varieties that have a white band around them looking as 

 though a sheet had been wrapped around the cow, at 89 Fahr. the 

 gravity was 108, and at 60, 106 ; I made an experiment with the 

 milk of the bob-tailed cow, allowing the milk to stand over night, 

 removing the cream ; the half skimmed milk at 60 Fahr. had a 

 gravity of 105, whereas the night previous at 60 it stood at 92 ; 

 your Honor will perceive that there was a gain of 13 degrees by the 

 lactometer ; if the buoyant power of the milk is expressive of its 

 goodness the half skimmed milk, by the lactometer, is better than 

 the milk containing all the cream ; I tested also at that place the 

 amount of cream which would rise on allowing the milk to be placed 

 in tubes 11 inches in length, and found that the milk from the first 

 cow mentioned as Uncle Richard's, as it is called, which stood at 

 110 on the lactometer, gave seven-eighths of an inch of cream ; the 

 one called the Indiana cow, which stood at 112, one and one-eighth 

 of cream ; the belt cow, which stood at 106 on the lactometer, gave 

 one and three-sixteenths of cream ; another cow, part Alderney, 

 which at a temperature of 60 gave a gravity of 108, yielded fifteen- 

 sixteenths of cream the first half of the milk, while the second half 

 of the milk of the same part Alderney cow which stood at 100 on 

 the lactometer gave two inches of cream ; the cow named Star, 

 which stood at 103, gave eleven-sixteenths of cream ; the bob-tailed 

 cow, which stood lowest of all in this series, 92 on the lactometer 

 at 60, gave an inch and a half of cream ; plainly showing that the 

 lactometer affords us no indication of the richness of milk in cream ; 

 I brought samples of his milks to my laboratory and submitted 

 some of them to chemical analysis, with the following result : With 

 the thousand-grained bottle, the gravity of milk, such as this, your
