warned wliat to suspect, and then, when speaking of the case to 
Dr. Thayer, he said that they had tuberculosis, for he saw them. 
December 20th, when I went to see the cattle, Dr. Winchester 
went with me to see the cases. We found cow No. 1 with a tem¬ 
perature of 103°, dullness on percussion on the lower third of the 
right lung, loss of respiratory murmur, dropping of the left ear, 
intermittent lameness, sometimes in one extremity and then in an¬ 
other, but generally in both hind legs. When in a box stall, she 
would travel in a circle for many minutes, and almost always with 
the right side toward the centre, and when walked in a straight 
line would go sidling along. 
We made a diagnosis of tuberculosis, ordered the animal to be 
isolated, and proposed to the owner that she be destroyed. 
To this he would not consent, but desired me to keep her along 
and let her die; she has, however, grown worse since December 
20th, and I saw her losing flesh; appetite capricious; loss of 
strength, and increase of circular motion, so that she would go 
round and round and then fall exhausted. 
Last Monday the owner gave me permission to destroy her, 
and taking Dr. Howard witli me, I went to the farm. 
On opening the right side of the chest, we found the lower half 
of the lung a mass of tubercular deposit, and adherent by a por¬ 
tion of its surface to the second, third and fourth ribs, which por„ 
tion I cut out, and reserved for you. The left lung was slightly 
affected. The liver, a portion of which you have, was studded 
with tubercles. I could find no tubercle in the mesentery. The 
ovaries were diseased. The one I cut was filled with fluid, and as 
you will see the other is similarly affected. Night coming on 
made our labors more like butchering than a careful post mortem. 
The cow No. 2 is wasting away, and I expect permission will 
be given to kill her in a few days. If so, I will try and get some 
more specimens. Yours, 
Bunker.

tuberculization, and with the symptoms given, a careful examina¬ 
tion of the brain and its envelope was not made.— Ed.]
