CHOREA. 
Ill 
cases where the vulval tissues were so nearly completely de¬ 
stroyed before any application was made. 
Another farmer some ten miles from this place had a herd 
of some thirty calves in which the disease made its appearance. 
He became somewhat alarmed and immediately disposed of 
them at considerable loss. In a few days he went out and pur¬ 
chased a like number in the surrounding country, placing them 
in the same yard and feeding them on the same rations. In 
about ten days these calves showed symptoms of the same dis¬ 
ease, and in a few days he was aware that they had contracted 
the disease. Hearing of his neighbor’s experience, he came to 
me for advice and information. It is useless to tell you I was 
loaded, and soon relieved him of his anxiety, prescribing the 
same remedies as before, and sent him on his way rejoicing. I 
make mention of this latter outbreak simply to establish more 
firmly the infectious nature of the offending agent.

Arnold’s cattle. On that day we found six or seven head of 
yearlings convalescing and two sucking calves acting as fol¬ 
lows :

noticed that the cattle all appeared in a natural condition. 
They were grazing naturally, ruminating, etc., as one would 
expect, and seemed to be contented. We gave our attention to 
a calf which was known to be showing the symptoms in their 
worst form. When this calf first noticed us it appeared to be 
slightly afraid. As soon as it was molested it began to mani¬ 
fest the symptoms. The first thing noticeable was a nervous 
motion of the head from side to side and slightly in an ellipti-
