26 TESTIMONY OF JOHN BLAKE WHITE. 



Q. When you enter a milk shop and a fluid resembling milk 

 which as far as you can tell by the exercise of your senses is milk 

 is given you, and you test it with the lactometer and thermometer 

 and note the result, can you tell whether the fluid you have tested 

 is milk or is something else ; I ask an affirmative or negative 

 answer. 



(Objected to as uncertain in this, that it does not appear by the 

 question whether the test proposed is by the lactometer and ther- 

 mometer alone.) 



The COURT I think I will permit you to ask this question, 

 whether he knows enough about the lactometer to say whether by 

 inserting it in a fluid looking like milk to know whether it was milk 

 or not. 



By COUNSEL Q. Can you tell by inserting the ]actometer in a 

 fluid that looks like milk whether it is milk or not ? A. No, sir ; I 

 cannot. 



Q. When you visit a milk shop and a fluid is presented to you 

 resembling milk and you test it with the thermometer and the lac- 

 tometer as you used those tests in the case of the accused, can you 

 tell from the result whether the fluid tested is milk or something 

 else? 



(Objected to ; objection sustained ; -exception.) 



Q. Dr. White, have you tested the milk of other animals besides 

 the cow with the lactometer ? 



(Objected to as irrelevant ; objection overruled.) 



A. I have not. 



Q. Have you ever tasted as far as you know the milk of any 

 other animal than the cow ? A. I do not remember whether I have 

 or not ; yes, I do remember, certainly ; it is so long ago that I for- 

 got it, I thought that was taken for granted. 



Q. Now, doctor, from the tasting of the milk, from noticing 

 whether it clings to the glass or the lactometer and from the test 

 usually made by you and as made in the present instance in the 

 case of the milk of the accused, can you tell whether the fluid you 

 tested is milk ? A. I think I can. 



Q. Will you swear positively that you can tell whether the fluid 

 you have tested is milk from these means ? A. I do not know that 

 that is required.
