PL EURO-PNEUMONIA IN CATTLE.

body was emaciated, his hair standing on end, his skin ad¬ 
hered to his ribs, he drank but little, and when food was 
offered averted his head, as if hardly conscious of his own 
existence. 
On examination of the chest, it was evident that there was 
consolidation of the lungs. I informed the owner that there 
was no chance of the animaPs recovery, when he said that 
he wished him to be destroyed at once. He was forthwith 
led from the stable, and with great difficulty taken to a field 
some forty or fifty rods distant, and there knocked on the 
head. He had been sick about two weeks. 
Post-mortem examination. — On opening the abdominal 
parietes, all the viscera were found to be healthy, except the 
liver, which presented a dirty-yellow hue, was quite soft, and 
when broken down exhibited a kind of disintegrated, coarse, 
granulated, degenerated mass. The diaphragm, on its abdo¬ 
minal surface, was healthy ; on its anterior or thoracic sur¬ 
face it was ulcerated throughout. The chest contained 
several gallons of a straw-coloured fluid. The lungs pre¬ 
sented an extraordinary appearance, being at least three 
times their usual size, of a dark-brown colour, almost black, 
and when cut into they were nearly solid in their whole sub¬ 
stance, except a small part of their anterior or bronchial por¬ 
tions, in which softening had commenced, while their inferior 
presented, when cut, a chequered appearance, of a dark-yel¬ 
low cast, but they were evidently tuberculated throughout 
their whole substance, and they adhered firmly to the walls 
of the chest. There was, however, a thick, tough, yellow 
lymph, of nearly an inch in substance, intervening between 
the pleura pulmonalis and the pleura costaiis. 
My employer seemed well pleased with my diagnosis, and 
also my demonstration, and promised me that of the next 
case which presented itself I should be immediately notified. 
Accordingly, on the 14th of November, I was informed of 
the sickness of two animals; one, a three-year old Devon 
heifer, the other, a four-month old, female, pure-bred, Ayr¬ 
shire calf. I immediately repaired to the spot, where I met 
Dr. E. F. Thayer. Upon examination, the following symp¬ 
toms were presented. Pulse quick and oppressed; respira¬ 
tion hurried, and accompanied by a sigh during inspiration 
and a grunt in expiration; the visible mucous surfaces 
highly injected; rumination suspended; appetite much im¬ 
paired ; bowels unusually constipated, the faeces being granu¬ 
lar. There was, on pressure of the intercostal spaces, 
extreme soreness evinced, particularly in the calf, with also 
a staring of the hair and a tightness of the skin.
