REPORTS OF CASES. 
Symptoms .—The animal suddenly goes off its feed, rumin¬ 
ation is suspended, the dorso-lumbar region is tender to pres¬ 
sure, a recumbent posture is almost constantly maintained, and 
what little time the animal is on its feet there will be rigors and 
trembling, but the standing posture is not long maintained ; the 
heart beats with violence against the thoracic walls, the pulse is 
small, rapid and irregular, the conjunctiva red and injected; 
blood escapes from the nose ; the eyes are sunk in the head and 
tears flow down the cheeks. The animal will sometime pass 
dark-colored urine ; temperature ranges from 103° to 106° or 
108 0 F. 
Etiology .—The outbreak referred to I think was due to this

the medium of ripe ticks, flies and the like. On post-mortem, I 
noticed the following lesions : Nothing of importance was noticed 
about the skin ; found considerable oedema of the subcutaneous 
tissue, which give a crepitus sound as filled with air. The lungs 
in some of the cases showed black hepatization, and a large 
amount of froth in them and bronchi. The heart contained 
petechial spots and the ventricles distended with black blood ; 
the kidneys enlarged and containing considerable oedema around 
them ; the spleen in all the subject I examined was greatly en¬ 
larged and full of black, thin blood ; on taking it out of the body 
the blood would gravitate on holding it up from one end to the 
other ; the liver was very much enlarged and of a pale color or 
sometimes mottled. I found more or less hyperemia in the intes¬ 
tinal track and messentery veins very much relaxed and escaped 
black blood ; bladder containing a small quantity of dark-colored 
urine. 
Treatment .—As most of the cows belonged here in the city, 
I had them kept in a good airy barn, allowed them plenty of
