TESTIMONY OF JOSEPH T. O'CONNOE. 153 



not want to bother myself. It was early in the morning, dark and 

 all that sort of thing, I just hurried through it. In the other state- 

 ments published there were some cows taken by some observers 

 wherein the thermometer was a little lower than 60, perhaps a 

 dozen. With that correction the statement is as you have it. 



Q. Doctor, will you be good enough to take your thermometer 

 and lactometer and tube and this exhibit of genuine cow's milk 

 taken this morning and test this sample of milk ; what is the tem- 

 perature ? A. It stands 108 in a temperature at 65. 



Q. Is the high temperature for or against the test ? A. If the 

 milk were cooled to 60 it would stand somewhat higher, how much 

 it is impossible to say without going through a series of experi- 

 ments. 



Q. Will you be good enough to pour out a part of that milk into 

 the pail, again fill it up with water and pour out about a quart of it ? 



A JUKOB I want to have determined for the jury the effect of 

 immersing the lactometer to show the number of degrees of differ- 

 ence, if any, that that would make ; also 'the other question is with 

 regard to the handling of the lactometer or hydrometer by a per- 

 son who does not understand anything about the principle of the 

 instrument. 



Mr. PRENTICE Perhaps it would be a better answer if we should 

 take one of these gentlemen who never made an observation before. 

 Will you be good enough to test it ? (Speaking to the interpreter 

 of the Court.) 



INTERPRETER The thermometer is 65 ; it went down to about 95 

 and now stands at 107. 



Q. Now wait till it settles ; read it again without wiping off? 

 A. It now stands at 105 ; I never in my life made use of the lacto- 

 meter before. 



Q. Haven't you studied chemistry ? A. I have been somewhat 

 conversant with it about 30 years ago. 



By Mr. PRENTICE Q. Now, Dr. O'Connor, if you will take out 

 those instruments so that it will be about one part water and three 

 parts milk. 



(Objected to.) 



Mr. PRENTICE - The question was asked by a juror upon which I 

 understand we substantially agree, namely, whether any person of
