TESTIMONY OF HENKY MORTON. Ill 



Q. How ? A. With the lactometer. 



Q. At what degree ? A. At 60. 



Q. Frozen milk at a temperature of 60 Fahr. at what degree 

 does milk freeze ? A. Excuse me ; I answered hastily ; I desire to 

 explain ; I of course melted the milk before testing it, my object 

 being to find what effect freezing had upon the density of the milk ; 

 I did not pay sufficient attention to your question ; the question 

 was asked, but I did not answer it. 



Q. You said something about frozen milk ? A. The question 

 was asked me, but I did not answer it. 



Q. By what lactometer did you test milk ? A. Chiefly by two. 



Q. Where did you get those ? A. One I obtained from the 

 Board of Health and the other was purchased by myself from Mr. 

 Tagliabue in Pearl street. 



Q. Did you compare the two? A. Only at one or two de- 

 grees. 



Q. Was there any variance between them ? A. There was a 

 little variance. 



Q. How much ? A. I think a degree or two. 



Q. Is there not a more accurate method of determining the pur- 

 ity of milk by its specific gravity in regard to adulteration by water 

 than that adopted by the Board of Health ? A. I think not, for 

 this reason ; allow me to explain my reason ; by rendering an instru- 

 ment more delicate or accurate nothing would be gained in practice 

 since we must allow a large margin on account of the variations 

 in the density of ordinary milk. 



Q. I refer to the use of an ordinary instrument as shown on 

 this trial to be used by the officers of the Board of Health, and I 

 repeat the question with that addition ? A. I think not. 



Q. Will you swear to that positively ? A. I will swear to my 

 belief. 



Q. Will you swear to more than a belief in the truth or correct- 

 ness of that answer ? A. I will swear that it is true. 



Q. Then you know of no other method which is better ? A. 

 Which is more accurate for this purpose ? 



Q. Yes, sir? A. No. 



Q. Do you know of any other that is better for any purpose ? A. 

 Analysis is better for the determining of caseine.
