None of the original animals reacted to the test, while the ani¬ 
mal which had been introduced from outside, reacted and was 
condemned, and upon post-mortem was found to be tuberculous. 
In the meantime a new barn had been built and was used as 
the home barn ; the old barns were disinfected as thoroughly as 
possible and the young stock and the dry cows were housed in 
them, the fresh cows being brought to the new barn as they 
came in. 
In the month of August, 1897, exactly one year after the 
previous test, the herd was again tested. At this time there 
were 154 animals at the home farm. These were all tested ; 22 
were condemned and killed as tuberculous and 32 were released. 
Five out of fifty-four at the second farm were condemned and 
one out of fifty-eight at the third farm was also condemned. All 
these cows were found to be diseased, the disease being very 
slight and confined entirely to the bronchial and mediastinal 
glands. 
It is but fair to state that another of the reacting animals was 
a registered bull, “ Sir Michael.” He had been kept isolated 
from the rest of the herd except when being used for service, 
since March, 1896, when he first reacted. At that time the tem¬ 
peratures were : 
8p. m., ioi ; 6 a. m., 101,101.2,103.4,104.4,104.3,104.2,104.3, 
104.2,103. 
June 13, 1896, 9:30 p. M., IOI.I ; 7:30 A. m., 102.3,103.1, 
103.1,103,103,101.3. 
August 18, 1896, 7:00 p. M., IOI. 2 ; 5:00 A. M., 101.1,101, 
102.2,103.4,104,103.4,103.4. 
And Aug. 18, 1897, 8:00 p. M., 101,101.1 ; 7:00 A. M., 101.2, 
103.1,104.3,105. 
This bull has been used for service on nine cows out of the 
twenty-two that have since reacted and were killed, one of the 
cows had been served as recently as July 21, 1897, or just about 
four weeks before the last test was made. 
The fact that none of the cows showed any traces of tuber¬ 
culosis except in the bronchial and mediastinal glands would
