gave well marked reactions. The barns were disinfected and 
the 16 cows, being mostly dry cows and springers, were isolated 
on one side of the barn, two partitions being placed between 
them and the other cattle. They stayed here until March 5th, 
when they were again tested, and at this time they gave 14 well 
marked reactions. The temperature of the other two cows at 
the second test read as follows : 
No. 129. ist test, Jan. 8, loi ;Jan. 9, 101-104.4, i 03 - 4 ) 103.2.

Both were killed, and on post-mortem examination proved 
to be diseased. The barns were again disinfected with bichlo¬ 
ride of mercury, 1:800, and whitewashed later. 
On the ist of May, 1897, the entire herd of 84 head were 
again tested, and this time 15 animals or 17 per cent, gave re¬ 
actions, and were killed. The post-mortem examinations 
showed these animals to have been only very slightly diseased. 
The barns have been twice disinfected during the summer 
and another test will probably be made in October. After every 
test, when cattle have been condemned, the herd has invariably 
been replenished with tested cows from Vermont. 
A second herd belonging to Mr. E. is another good illnstra- 
tration of the difficulty in thoroughly disinfecting barn After 
being first tested and cleaned up in Oct., 1894, this ^ 
retested on March 17th and i8th, 1896. There e-re So cx Uvi: 
in the herd, 78 of which were tested, 2 animals having a .eih- 
peratnre too high at the time to be injected. Fourteen animals 
reacted or showed a suspicious rise in temperature ; they were 
immediately separated from the remainder of the herd, were 
again retested June 19th and 20th, at which time two were re¬ 
leased, three were condemned and nine were continued in quar¬ 
antine. On Oct. 7, 8 and 9, these nine quarantined animals 
were tested and condemned. 
On Aug. 16 and 17, 1896, sixty-four of the original herd and 
one animal which had been introduced recently were tested.
