70 TESTIMONY OF CHARLES F. CHANDLER. 



normal condition that you had that the milk had been tested by the 

 lactometer ? A. I had not. 



Q. You were present at the trial of John Kneib which I have 

 alluded to, throughout, were you not ? A. I believe so. 



Q. You heard the testimony of Doctor Doremus ? A. I did. 



Q. "Was not your attention then called to several cows the milk 

 of which was said to have been tested by the lactometer and found 

 at various points below 100, and which milk was sworn to have 

 been analyzed and the analyses produced ? A. My attention was 

 called to that statement. 



Q. Is not one of your arguments in favor of the lactometer that 

 it is a test which the milkmen themselves can apply ? A. Yes, sir ; 

 in connection with their senses. 



Q. You do not think it necessary to use the thermometer in 

 testing milk ? A. Only to avoid trouble in trials ; I do not consider 

 it absolutely necessary to use the thermometer when one tests milk 

 who has any experience in judging of temperature. 



Q. There are two methods to test your lactometer, are there 

 not? A. Yes, sir. 



Q. One is by the hydrometer ? A. That is by comparing it with 

 another lactometer or hydrometer which is known to be correct. 



Q. And the other is by the specific gravity bottle, I believe ? 

 A. The other is by placing it in liquids of known specific gravity. 



Q. Which is the best of those two methods V A. Both are 

 equally accurate. 



Q. Did you not yesterday testify that the test by the hydrom- 

 eter was the best of the two ? A. I do not remember that I did ; 

 if I did it was simply because it was the quickest and simplest. 



Q. If you did so testify were you mistaken ? A. Do you refer 

 to the test of the specific gravity of milk or the accuracy of the 

 lactometer ? 



Q. The latter. A. I do not recollect what I stated with regard 

 to those methods ; my impression is that I was not examined on 

 testing the accuracy of the lactometer but on determining the spe- 

 cific gravity of liquids ; in either case however to test the accuracy 

 of the lactometer by comparing it with another lactometer which is 

 known to be correct is the better method of the two, for the reason 

 that it is simpler ; in either case it will . be necessary to float the
