BOVINE DIPHTHERIA.

tance of about three miles, by being led. Thrice on the way 
she had paroxysms of choking with acute ptyalism anda copious 
discharge from the nostrils. After a short rest she would again 
resume her walk. During the distance she did not cough. The 
bowels remained torpid, but there was an abundant discharge 
of urine. At the end of her journey she was turned into a yard 
and left for the night. 
The next morning, June 28th, at nine A. m. I found her 
dead, lying with the head to one side and on her sternum. 
There was no evidence of a struggle, and under the mouth was 
quite a pool of saliva. Post-mortem at ten A. M. No bloating, 
skin wrinkled with the appearance of parchment, pupils dilated 
and a general shrinking of the entire body. The mucous mem¬ 
brane of the vagina was red with a mucous discharge from the 
same. On removing the skin the veins under it were filled 
with blood, and it adhered as if the animal had been dead two 
or three days. The abdominal viscera were apparently normal, 
with the exception of the kidneys, which presented centres of 
congestion. The larynx presented numerous grey elevations 
well defined ; the mucous membrane at the base of the epiglottis 
was thickened and rough. The mucous membrane of the 
trachea and large bronchial tubes was studded with petecchial 
spots, and at places the ecchymosis was confluent. The smaller 
bronchi were filled with a frothy secretion. Pericardium con¬ 
tained considerable dark colored fluid. Ecchymotic spots were 
well defined over the surface of the heart, while along- the edges 
of the auricles under the serous membrane there was a well-de¬ 
fined yellow serous exudate. The external coats of the large 
blood vessels at the heart were studded with ecchymotic spots. 
On opening the heart it was found to contain semi-coagulated 
blood, which was in evidence through the system. When the 
meninges of the brain were opened there escaped considerable 
clear serum. The blood vessels of the brain on the surface and 
in the sinuses were engorged with blood. The plexi of the 
ventricles were filled with blood, and the cavities contained con¬ 
siderable clear fluid.
