TESTIMONY OF CHARLES A. DOBEMUS. 225 



was in the first case, and yet there was seven degrees difference on 

 the lactometer, showing that the lactometer will not tell the amount 

 of water either adulterated or naturally present in the milk. 



By Mr. PRENTICE Q. Is that your opinion ? A. That is my 

 opinion ; the two last cows were fed on pasture and some pump- 

 kins. 



Q. How many cows have you of Clark's dairy? A. There 

 were fifteen cows and three went below 100 ; the highest one was 

 at 115, the table is at your disposal ; I visited another dairy, Uncle 

 Richard's, but unfortunately they had commenced milking before 

 I arrived there, so I only had a chance of testing the milk from five 

 cows, and they all went above 100 ; I tested therefore in all thirty- 

 seven cows and got 8 samples below 100 ; a fifth of the cows there- 

 fore gave milk less than 100. 



By Mr. WAEHNER Q. Now, Doctor, did you make an analysis 

 of the milk contained in that mysterious bottle ? A. I did, sir. 



Q. That was No. 3 ? A. No. 3. 



Q. What were the results ? A. I found 90, 668 of water, butter, 

 1.94, caseine, 7.305, salts, 0.087 ; I would like to state in regard to 

 these analyses, that I would not like to say that they were absolutely 

 correct, for I was very much pressed for time and had not the pos- 

 sibility of going into it as I did with the other analyses ; the other 

 analyses were very carefully made, but I think that Prof. Chandler's 

 analyists will substantially agrees with these analyses. 



Q. Now, sir, have you examined the instrument known as the 

 lactometer ? A. I have, sir. 



Q. Can you enumerate to this jury any mechanical defects con- 

 nected with that instrument ? A. Besides those defects showing 

 that the instruments did not agree, I could point out that the 

 scale is not properly graduated according to the rules laid down in 

 scientific books ; if you will hand me Watts' dictionary, I would 

 like to refer to that. 



Q. What page do you cite in support of that proposition ? A. 

 206, Vol. 3, under the subject called gradation, showing that the 

 degrees on the gradation should not be equal ; this is applied to all 

 hydrometers ; I would like to have Hoppe-seyler. 



By Mr. PRENTICE Q. That is the other book you cite in con- 

 firmation of your views ? A. Hoppe-seyler ; I do not know the page,
