MELJiNA IN COWS. 
minute 74; the coat staring; the back roached; the skin 
tinged yellow ; the rumen and omassum full. She voided 
frequently an immense quantity of liquid and coagulated 
blood, mixed with feculant matter of a dark brown colour ; 
indications of vomiting showed themselves, and after several 
attempts, she succeeded in ejecting from the mouth matter 
similar to that passed anum. 
In such a case as this, it was but too evident that what 
was to be done was to be done quickly ; and having marked 
out my course, I immediately proceeded to put it into effect, 
which was first to throw several bucketfuls of cold water over 
her, then to cover her up with horse-rugs, and give the 
following draught : 
Ijl 01. Lini, Ojss ; 
Pulv. Opii, 5ij ; 
Hydrargyri Chlorid., 5ss ; 
Pulv. Zingiberis, 5ij ; 
01. Juniperii, ^iij. Misce. 
This was followed in an hour and a half after, by — 
Lini Oleum, Ojss, cum Terebintliinse Oleum, §iv ; 
and small quantities of the latter were ordered to be ad- 
ministered several times during the day. 
At night I found her much better. A little dark, soft, 
offensive dung was being passed occasionally. After this, 
small doses of diffusible stimulants, combined with vegetable 
tonics, and a strict attention to diet, brought about a state of 
perfect convalescence in about nine days. This cow t I had 
treated some months before for pleuro-pneumonia epizootica. 
Case 2. — During the time I was attending the foregoing 
case, another cow was attacked in a somewhat similar manner. 
She was near calving, rather poor, and had pleuro-pneumonia 
epizootica about the same time as the other. It may be as 
well to observe, that the last-named complaint had been pre- 
valent on that farm for three years, and this cow, with the 
others, had been at grass about three weeks upon a peaty, 
and, in some parts, badly drained field, in a low situation, the 
weather not being over genial for the month of May. 
The ears, horns, pulse, &c., were in the same condition as 
the first case. The action of the heart was so violent as to 
be heard at some distance, and at every beat it seemed to 
shake the whole frame. She purged an immense quantity of 
dark liquid, mixed with coagulated blood, &c., but she did 
not vomit.
