92 TESTIMONY OF GEORGE C. CALDWELL. 



Q. How do you know it was pure milk ? A. I do not know as 

 I can say from positive knowledge. 



Q. You said so a moment ago ? A. I must qualify my answer ; 

 I had every reason to suppose it was pure milk. 



Q. Will you swear, from the inspection you made, that that fluid 

 was milk at all ? will you look at this, and state whether it is milk 

 or some ther composition? 



(Objected to.) 



Q. You could tell the fluid you tested was milk ? A. I knew 

 that the fluid that I tested was milk. 



Q. How did you know it ? A. Because it was furnished me by 

 a family that has always supplied it ; it was taken from a portion 

 of milk used by my family that day. 



Q. Is that the only reason you knew it was milk ? A. That is 

 the only reason I knew it was milk. 



Q. Aside from that, you did not know it was milk ? A. That is 

 all the reason I have for supposing it was milk. 



Q. And yet you, as a distinguished and scientific gentleman, 

 from that assumption, testify that you had knowledge that it was 

 pure milk ; is that it? A. I testify it was pure milk. 



Q. Suppose I assure you that this bottle contains pure milk and 

 nothing else, and you examine it with the lactometer and thermo- 

 meter, and, in short, make just the same examination as you made 

 at Ithaca, will you then state whether this is milk or not ? 



(Objected to; objection sustained; exception.) 



Q. If a fluid should be presented to you looking, tasting, smell- 

 ing, and to the touch, like milk, clinging to the lactometer, and at 

 60 Fahr. showing 90 on the lactometer, would you give it as your 

 opinion that the article was milk ? 



(Objected to ; objection overruled.) 



A. I should not be able to say positively. 



Q. In your opinion, could any other scientific expert say posi- 

 tively? 



(Objected to.) 



Q. We submit this question to the witness, whether or not 

 analysis is not the only method of determining whether an article 

 is milk? 



(Objected to ; objection overruled.)
