194 TESTIMONY OF ROBERT OGDEN DOREMUS. 



Q Do the tests made by Dr. White in the shop of the accused, 

 as testified to by him, show whether the fluid tested was adulterated 

 milk ? A. They do not. 



Q. From such tests, if made by yourself, would you be willing 

 to give it as your opinion that the fluid tested was adulterated? 



(Objected to ; objection sustained ; exception.) 



Q. If you had made the tests in this case made by Dr. White, 

 would you have been willing to testify that the fluid tested was 

 adulterated milk ? 



(Objected to ; objection sustained ; exception.) 



Q. Now, what causes may vary the specific gravity of pure milk ? 

 A. I have mentioned that water would make it lighter, and cream as 

 accomplishing the same result ; cheese, sugar, and salts, reversing 

 this in fixing the gravity ; the condition of the cow ; the period after 

 calving ; the nature of her food, and so on. 



Q. Will the pasturing on which the cows are fed vary the gravity 

 of the milk? A. It will. 



Q. Will the question whether the cows are or are not fed with 

 salt vary the gravity of the milk ? A. It will. 



Q. Now, does the specific gravity of the milk usually change as 

 it grows older ? A. The gravity of the milk we have found by ex- 

 perience to change as we bring it from the country into the city, 

 even that brief time, and after a day or so it changes again ; what 

 this is due to is obscure, though many claim that it is a peculiarity 

 of the cheese portion of the milk, not from the loss of any one of its 

 ingredients, but the condition of the caseine or cheese. This is a 

 well established fact. 



Q. How does this affect the lactometric test ? A. This would 

 cause the lactometric test at the dairy to be one thing, and at the 

 city another. 



Q. Now, what is the effect on the specific gravity of the milk of 

 adding brackish water ? 



(Objected to ; objection sustained ; exception.) 



Q. Dr. Doremus, is not the butter in the milk strictly nutritious 

 and important ? 



(Objected to ; objection sustained ; exception.) 



A. What ingredients in milk vary most in quantity ? A. The 

 water, caseine and butter.
