TESTIMONY OF JOHN BLAKE WHITE. 33 



Q. How do you cool it when it requires cooling ? A. "We cool it 

 with ice water place it. in a glass containing ice water and cool 

 it. 



Q. How do you warm it ? A. Warm it in a vessel containing 

 warm water, and sometimes with my hands ; I have often warmed 

 it with my hands. 



Q. Do you state what you do in your laboratory or what you do 

 in the shops? A. I state what I have done in some cases in the 

 shops and always in the laboratory. 



Q. Now you said, Mr. White, that the temperature varied 2 de- 

 grees of specific gravity for 1 on the lactometer ? A. No, sir ; I 

 said the average was 2 degrees on the lactometer for 3 in temperature; 

 that was about the variance. 



Q. You do not mean then what it varies in degrees of specific 

 gravity, but degrees on the lactometer ? A. The lactometer in- 

 dicates the specific gravity of the fluid when it is tested. 



Q. How many degrees of specific gravity are indicated by any 

 degree on the lactometer ? A. The 100th mark on the lactometer 

 indicates a specific gravity of 1.029. 



Q. What degree on the lactometer indicates 1.018 of specific 

 gravity ? A. About 89 I should say. 



Q. Now, sir, have you any regular scale of allowance to be made 

 in testing milk if the temperature is above or below 60 Fahr. ? A. 

 I have no scale ; no sir. 



Q. Can you give a regular scale ? A. I have just stated that it 

 varies 2 degrees in specific gravity ; the degrees on the lactometer 

 indicate the specific gravity of the fluid in which it is placed. 



Q. The difference between 100 on the lactometer and 99 on the 

 lactometer indicates 1 degree in specific gravity ? A. Yes, sir." 



Q. Now you always test the milk exactly at 60 ? A. Not always ; 

 when I first test it, it may be higher and I cool it to 60 after- 

 wards. 



Q. Can you state what temperature the milk of the accused was 

 when you went in there ? A. I cannot. 



Q. Had you cooled it or warmed it ? A. I do not remember, it 

 was at 60 when I tested it. 



Q. What does it weigh ? 



(Objected to ; objection sustained ; exception.)
