102 TESTIMONY OF HENRY MOETON. 



Q. In making a test upon the result of which such a prosecution 

 was intended to be based, how far would you regard yourself as 

 being justified in departing from the standard of extreme accuracy ? 

 A. I would require such accuracy that, the extreme limit of error 

 being admitted, my conclusion would be irrefutable. 



Q. Then you would not regard it as necessary to use the best and 

 most accurate method that science could devise ? A. I would not. 



Q. You say if the lactometer differs the tenth part of a degree, 

 or is not accurate to that extent, that will not endanger the accu- 

 racy of the test, do you not? A. I said substantially what you 

 mentioned, but did not intend to limit myself to the tenth part of a 

 degree of the lactometer. 



Q. Suppose it differed the hundredth part of a degree ? A. That 

 would not injure the test. 



Q. Suppose it differed a tenth ? A. That would not injure the 

 test. 



Q. Suppose it differed a degree ? A. That would not affect the 

 test. 



Q. Suppose it differed two degrees ? A. I do not think then it 

 would be impossible. 



Q. Suppose it differed three degrees ? A. The question would 

 presently resolve itself into whether at that point or soon after there 

 would be one involved on which the main question hung ; if in the 

 specific case the adulterated material showed 50 per cent, of water 

 I should consider that an error in the lactometer, of three or five 

 degrees was of no importance. 



Q. Suppose the adulterated fluid appeared to be adulterated to 

 the extent of 15 per cent., would you regard an error in the lacto- 

 meter of three degrees as being important ? A. I should regard it 

 of small importance. 



Q. Take the case put by Prof. Chandler, assuming the cow's milk 

 to be 120 and therefore that the lactometer will not detect adulter- 

 ation to an extent of 15 per cent., in that case would a variation or 

 inaccuracy in the lactometer of one degree be important? A. Your 

 question involves a statement which I do not understand Dr. 

 Chandler to have made. 



Q. Understand the statement as coming from me as a hypothe- 

 tical question if you choose ? A. I must in that case, in the first
