TESTIMONY OF CHARLES F. CHANDLER. 83 



for watering. One test is for one object and one for another ; each 

 is sure for its own object. 



Q. Is not analysis a surer test ? A. Not for excessive water- 

 ing. 



Q. In the Kneib case were you not asked by me : " You would 

 adopt another test ; would you not? " and did you not answer ; " Yes, 

 sir?" Then were you not asked "Would not analysis be a surer 

 test " ? and did you not answer, " Yes sir ? " A. I think very likely, 

 I entertained an opinion of that kind at that time. 



Q. You have changed it since ? A. I have learned a great deal 

 since. My confidence in the lactometer has been increased ten-fold 

 since that case was tried. 



Q. From your opinion as it is at present, is analysis of milk made 

 by an expert chemist, thoroughly and fully, a surer test than the use 

 of the lactometer accompanied by all that the inspector testified to 

 in this case ? A. Not for watering. 



Q. Is analysis thus made better and surer for the purpose of 

 ascertaining whether the fluid is milk ? A. Yes, sir. 



By COUNSEL FOR THE PEOPLE Q. Doctor, you were asked some 

 questions about the Dictionary of Chemistry by Watts, and were 

 called upon to read some extracts ; please look at that article again 

 and tell me if the title of the article related to the analysis of milk 

 or whether it was some other subject ? A. They related to the 

 analysis of milk that is the subject. 



Q. Does that article which you have in your hand, the part 

 which you read and its treatment of the particular subject under 

 the title of analysis of milk, confirm, or, as you understand it, is it at 

 variance with your opinion of the value of the lactometer as a prac- 

 tical test for the adulteration of commercial milk found in cities by 

 the addition of water? A. It is in full accord with my opinion on 

 the subject. 



Q. Doctor, you were examined upon this edition of the book 

 Du Lait, published in Paris in 1859 ; I ask you to turn to pages 192 

 and 193, and the table therein contained, the observations of 102 

 cows, and also the resume on the following pages ; the resume of 

 those tables of observation, the density of the milk, the analysis of 

 it, and the average, the minimum and the maximum ? A. I have 

 done so.
