210 TESTIMONY OF HENRY?, 'Wl TBAUGHAN. 



Q. If it fell below a certain degree ? A. Yes, sir. 



Q. Then take a case of absolutely pure milk from a well fed 

 healthy cow and a test is made with the lactometer ; doesn't it show 

 a less degree of gravity than in a case of skimmed milk? 



(Question objected to by the prosecution ; overruled by the 

 Court ; exception taken.) 



A. It does. 



Q. Then in a case of skimmed milk where the lactometer would 

 show a higher degree than in a case of absolutely pure milk, if you 

 desire to ascertain whether the skimmed milk was adulterated it 

 would be necessary for you to make an analysis, wouldn't it, as a 

 sure test ? A. I should say not. 



Q. Then do I understand you to testify that the lactometer when 

 inserted in skimmed milk, would be a sufficient indication to your 

 mind, if it showed a certain gravity, that the milk was adulterated, 

 simply by the test of the lactometer ? 



(Question objected to by the prosecution ; overruled ; exception 

 taken.) 



Q. Take a sample of skimmed milk and insert the lactometer, 

 and if it should show a certain degree above 100 degrees, would 

 that be a certain indication to your mind that the milk was adul- 

 terated, or would you require to make an analysis first to satisfy 

 you that the milk was adulterated ? A. The fact that the lactome- 

 ter stands higher than in pure milk would be proof positive to my 

 mind that the pure milk has been adulterated by water to make it 

 skimmed milk. 



Q. Aren't there certain substances, which if put into skimmed 

 milk, would make it show higher on the lactometer ? A. Yes, sir. 



Q. Skimmed milk will show higher than pure milk ? A. Yes, 

 sir. 



Q. It does- show higher than pure milk ? A. Yes, sir.
