138 TESTIMONY OF HENRY A. MOTT, JR. 



By Mr. LAWRENCE Q. Did you make the test by the lactometer ? 

 A. I made the test by the lactometer which I had procured and 

 which I had verified by first obtaining the specific gravity by an 

 instrument, and then by weighing the milk on the scales. 



Q. Did you use the thermometer in making those five tests with 

 the lactometer ? A. I did ; I wished to have my results scientifically 

 accurate. 



Q. At what degree ? A. At 60 degrees Fahr. 



Q. Did you make any memorandum of it at the time, showing the 

 results of that examination ? A. Yes, I think I did. 



Q. Have you it with you ? A. I have not. 



Q. When did you make those five tests, Doctor ? A. I made them 

 between December and February of last year : I made other tests 

 since then. 



Q. December of last year, and February of this year ? A. Yes, sir. 



Q. Among the articles that you have published on this subject 

 did one appear in the New York Herald on the 14th February, 1876 ? 

 A. It did, sir. 



Q. State whether I read correctly from that article : " I have 

 frequently met with samples of fresh cow's milk having a specific 

 gravity between 1.029 and 1.030, but only once have I ever found the 

 specific gravity below 1.029. The sample I refer to was milked from 

 an Alderney cow owned by a gentleman at Nyack, which gave a specific 

 gravity of 1.028.64 at 60 Fahr. ; on analyzing this sample the milk 

 proved richer in milk solids than any milk I have been able to find 

 recorded," is that correct ? A. That is correct, but I wish to explain ; 

 I had at that time a gentleman in my laboratory whom I requested 

 to obtain a sample from an Alderney cow at Nyack ; he obtained the 

 sample, I tested it, believing it to be a fair average sample of that 

 particular cow thoroughly mixed together, and I believed the cow to 

 be in a perfectly healthy state ; I afterwards found that he was not 

 present when the sample was obtained, and could not give me anv 

 evidence that the sample was a fair average of all the milk ; not 

 knowing that the results were correct for that particular sample, 

 but not for milk in general. 



Q. The assistant Avho did all this, was he the same assistant who 

 gave you the information of the purity of 5 samples ? A. I did not 

 say he was an assistant, he was a gentleman in my laboratory.
