ON CHOLERA IN DOMESTICATED ANIMALS. 
the stock of one of his lordship’s farmers, near Bervie, with a 
view to ascertain the cause of a disease which prevailed there, 
and of which forty-three beasts had died during the season. The 
animals which I saw were affected in a way precisely similar to 
the horses in this part of the country, and which was described 
by the farmers as a closing, from the difficulty of breathing’ 
occasioned by the inflammation of the larynx and mucous mem¬ 
brane of the bronchi. 
In all the cases the symptoms presented a close resemblance. 
The pulse ranging from seventy to ninety, in many cases irregular, 
in some rather small and oppressed, and with a degree of feeble¬ 
ness ; while in a few others it was hard and bounding. In tlie early 
form of the disease, the respiration was rather confined than op¬ 
pressed, and was marked more by contraction of the abdominal 
muscles and drawing up of the flanks than by increase in the 
frequency or extent of their action. The respiratory murmur, 
when the ear was applied to the throat and sides, indicated a 
morbid secretion of mucus in the air-tubes, which could always 
be heard while they remained pervious. There was commonly 
sore throat and some cough ; but the cough was not considerable ; 
01 % when it became so, was symptomatic of returning health and 
strength. The mouth, generally, was hot but moist, and rather 
filled with mucus : when otherwise, the tongue was foul, with a 
crust upon it, and the breath had a cadaverous smell. The 
strength soon became prostrated. The bowels were, in general, 
very easily acted upon, and a good deal of caution was neces¬ 
sary in the administration of laxative medicine, as the over¬ 
excitement of the bowels had a strong tendency to increase 
the fatal termination of this disease. 
Examination after death shewed the malady to be an inflamma¬ 
tion of the bronchial membrane, especially in the minutest portions 
of the air-tubes ; terminating in the formation, first of tubercle¬ 
like masses in the substance of the lungs, and which afterwards 
rapidly burst into abscesses, forming innumerable vomicae, more 
especially towards the lower edges of the lobes of the lungs, or in 
the small lobes or portions anterior to the heart. A minute in¬ 
spection seemed to indicate an interruption to the blood in the 
minute vessels as it was passing through the lungs from the right 
to the left side of the heart, and which, where it became ob¬ 
structed by the morbid obliteration of the vessels, was coagu¬ 
lated and broken down, and aided in the formation of the 
tubercles and the abscesses. In these respects the epizootic 
differed from that which occurred six or eight months before, 
because in the animals which died at that period, there was 
only simple inflammation, with hepatization of portions of the 
lungs, but without the tuberculous formations.
