TESTIMONY OF EGBERT OGDEN DOREMUS. 203 



of pure milk from the cow more likely to depend upon the quantity 

 of water in the milk than upon the weight of all the other constit- 

 uents of the milk or not ? A. Your Honor, I consider that the 

 cream balances the water, for the reason that as I have shown some 

 of the lowest gravity of milks exhibit the cause of their low gravity 

 by their abundance of cream, not water. 



Q. Is it not more likely could you ascertain by the lactometer 

 the specific gravity of a certain given quantity of milk ; it is conceded 

 that if that is properly graduated, it ascertains that fact without 

 making any further analysis or investigation as to the relative 

 weights of the different constituents of milk ; is not the specific 

 gravity of that milk more likely to depend upon the weight of the 

 water it contains, than the weight of all the other constituents of the 

 milk, the weight of the water as shown by experience being much 

 greater ? A. I think that the most that can be said, if you omit the 

 cream relationship that I speak of, is that it is merely suspicious 

 and only warrants one to make a further examination such as the law 

 in Paris requires, that if the lactometer is very low, then be cautious 

 to take a sample and submit it to a chemist for an examina- 

 tion. 



By Mr. PRENTICE Q. This is an instrument that you have tes- 

 tified to before as used for what purpose ? A. For testing the 

 gravity of alcohol. 



Q. What do you call it ? A. An alcoholometer. 



Q. How much greater is the range of scale on this instrument 

 than on the lactometer ? A. Well, sir, it passes from the gravity of 

 water to the gravity of pure alcohol. 



Q. In degrees, how much greater is the range of this scale 

 than that ? A. It is apparent to the eye ; it is nearly twice the 

 length. 



Q. I am not talking about the measure, I am talking of the 

 number of degrees ; if the degrees on this instrument were as long 

 as the degrees of that instrument, would not this instrument be 

 very much longer ? A. It would be longer, but the principle would 

 be the same. 



Q. Would it be over 6 feet longer ? A. No, sir, I do not think 

 it would. 



Q. It would be very much longer than this ? A. It would be
