152 TESTIMONY OF JOSEPH T. O CONN OK. 



Q. What was the reading of these three exceptional cases ? 

 A. One was 96, one was 95, and one was 93. 



By the COUKT Q. Were these cows in pasture ? A. They were 

 with the regular herd ; of course they were milked under my obser- 

 vation. 



Q. Was there running water in the field ? A. The springs had 

 dried up, and they had to go a distance for water ; but whether the 

 water was in their own field or whether they were allowed 

 to go out at certain times to get water, I of course could not say. 



By Mr. PEENTICE Q. Have you ever known the milk of a sound 

 healthy cow, in a normal state, under normal circumstances, to fall 

 below that rate ? A. No, sir, I have not. 



Q. Below 100 on the lactometer at this degree ? A. Yes, sir, not 

 below 100. 



Q. Have you tabulated the tests made by all the inspectors of the 

 Board of Health at the dairy farms of single cows ? A. I have 

 tabulated all the observations as published, and in addition I have 

 tabulated a report of mine, which has not yet been published, but 

 have not tabulated all, for the reason that four or five cows taken 

 by Dr. White, were not in my possession at the time I made up the 

 table. 



Q. Were they city cows or country cows ? A. I believe they 

 were city cows ; I am not in a position to know ; the country cows 

 I examined all. The average result of the observations, excluding 

 the four cows that were found altogether, was 109.8. I beg pardon; 

 I should say including those four cows, the average result was 109.8 ; 

 excluding those four cows, the result established, the average 

 observation, was 109.9. 



Q. How many cows? A. Aggregate number, including the four 

 sick cows, was 401. 



Q. On all these tests of cows at the dairy farms, including the 

 four sick cows, with the thermometer marking a temperature of 60 

 Fahr., the average degree upon the lactometer was 109.8? A. If you 

 will allow me to make one correction which has partly been shown 

 by what I have already said. It is substantially correct, that is to 

 say, there were thirty-one cows in which almost all were taken at a 

 temperature of 62, I mean the milk of cows, some a trifle over, but 

 when the lactometer showed me a sufficient amount I certainly did
