TESTIMONY OF CHARLES F. CHANDLER. 87 



be at other points, as I had not retained a record of the original tests 

 of these lactometers, I very carefully verified four points on each of 

 those lactometers last night ; in addition to 100 which had pre- 

 viously been verified. At the 104 mark, they agreed exactly ; three 

 of them were correct at 88, the fourth marked 87 ; at 78 two of them 

 were correct exactly, one marked 77 and one marked 76 ; at 68 two 

 were correct, one marked 67 and one marked 66 ; the greatest de- 

 viation being two degrees, and that at points which are unimport- 

 ant, as being far away from the standard of 100. 



By COUNSEL FOR DEFENDANT Q. We would like to ask the wit- 

 ness to produce those four lactometers? A. I have only one of 

 them here. 



Q. Are the others here, Doctor ? A. I can ascertain by exami- 

 nation. 



Q. You have explained, I believe, Dr. Chandler,- what you have 

 intended by the term commercial milk, that it is a milk received 

 here in the city of New York and offered for sale in forty-quart 

 cans ? A. I have. 



Q. It is mixed milk, is it ? A. It is. 



Q. You have testified that when you testified in the Court of 

 Special Sessions in the Kneib case, Mr. Wanklyn's book and the 

 other books containing the extract were not before you ; were they 

 not in court at that time ? A. I presume they were in the hands of 

 the experts on the other side of the case and were read by them. 



Q. Did you make any attempt to get them into your hands ? 

 A. I have no recollection of trying to do so. 



Q. Did you or did you not ? A. I cannot say whether I did or 

 not ; I presume not. 



Q. Were you at that time satisfied that they were correctly read ? 

 A. I had no reason to doubt it. 



Q. Were you satisfied that they were or do you now remember 

 that they were then correctly read ? A. I have no reason to doubt 

 it. 



Q. What is analysis, is it not a system of testing ? A. Analysis 

 is taking things to pieces. 



Q. Is it not one means of testing milk ? A. Yes, it is one 

 method. 



Q. Take this table of Quevenne and look through pages 194, etc.,
