 A. Nothing further than what the lactometer explained. 



Q. You didn't see it milked? A. No, sir.

 eter in connection with the lactometer ? A. I think it was in July,

 meter. 



Q. Did you verify the lactometer that you used ? A. I did 

 not.

COUNSEL I move to strike out so much of this gentleman's testi- 

 mony as relates to making tests of milk by means of the lactome- 

 ter ; that he sampled 10,000 cans of milk by the lactometer, on the 

 ground that he is not an expert. 



The COURT I will decline to strike that out. 



COUNSEL I except to that; I move to strike out so much of his 

 evidence as relates to the tests of milk made by him with the lac- 

 tometer that covers the country milk. 



The COURT I won't strike that out. 



COUNSEL I except to that.
