for a week in varying temperatures would present the same results 

 that came from this fluid tested by you ? A. Yes, sir. 



Q. Now what was the appearance of this fluid ? A. In which 

 way, sir, under the microscope or in the 



Q. Under the microscope ? A. There were a large of number fat 

 globules which are of course always present in any milk fluid, that 

 is to say in fluid made by the admixture of milk or in an emul- 

 sion. 



Q. Did you take the specific gravity of this fluid ? A. I did not. 



Q. How much butter did you find contained in it ? A. I made 

 no chemical analysis. 



Q. You simply made a microscopic test? A. A microscopic 

 test. 



Q. And never have tested milk a week old before with the mi- 

 croscope ? A. No, sir. 



Q. Now suppose the milk which you saw come from the black 

 cow was kept for a week in varying temperature, might it not at the 

 end of the time present the same phenomena you noticed in this 

 sample ? A. It could not present as a result of its keeping those 

 bodies we term pus corpuscles. 



Q. These corpuscles which you found in the other fluid ? A. 

 Yes, sir. 



Q. Now do you infer that anything had been added to this milk? 

 A. Not at all. 



Q. Now, Dr. O'Connor, what, as far as you saw, was done with 

 the milk from the various cows at Mulford's, including the strip- 

 pers ? A. As far as I saw all the milk was placed in a can, with the 

 exception of the milk from three cows which was equally divided, 

 or nearly so, in each case between Mr. Doremus and Dr. Waller, 

 they taking about half if I remember rightly ; I think in each case 

 they took all ; I am not quite sure. 



Q. Can you tell whether that milk was not sent to New York ? 



A. No, sir ; I cannot tell that it was not sent to New York. 



Q. Did you examine the cows from which some of this milk 

 came ? A. In a cursory way by looking at them. 



Q. Did you detect anything unhealthy about them externally ? 

 A. I saw nothing special externally ; they looked rather rough, that 

 is all
