252 TESTIMONY OF JOSEPH T. O'CONNOR. 



pired from the time I got it, milk even at this temperature would 

 have turned sour. 



Q. What time was it ? A. It was a week ago last Monday, as I 

 understand it. 



Q. Then you pronounced it unhealthy because it soured within a 

 week ? A. It had not soured in the first instance. 



Q. Do you know at what temperature it had been kept ? A. I 

 do not know, sir. 



Q. You stated just now, sir, what healthy pus was ; will you 

 state what unhealthy pus is ? A. Unhealthy pus cannot be de- 

 fined ; as far as I take it there are various varieties ; I would simply 

 state that in all pus these peculiar bodies termed pus-cells are 

 present. 



Q. Now, sir, is not all pus unhealthy ? A. I said healthy pus, 

 I meant to say laudable pus.

 this milk? A. Yes, sir.

 blood in such immense numbers as I saw them, except under con- 

 ditions of inflammation, and then they are termed pus. 



Q. Well, sir, did you ever apply the microscope before to milk 

 that was a week old ? A. I did not, sir, to milk a week old. 



Q. Now can you state that at the end of a week milk a week old 

 would not present the same results as were obtained by you from 

 your analysis of this fluid milk kept at varying temperatures I 

 mean, sir ? A. No milk, no matter how long it could be kept, could 

 have pus corpuscles develop in it ; pus corpuscles must have been 

 there when the milk was drawn. 



Q. Is it your opinion that no healthy milk which had been kept
