TWO CASES OF EPIDEMIC. 279 
lifted her fore feet up remarkably high and with a jerk, not unlike 
a horse with the stringhalt. 
Symptoms of the cow. — She lay down quietly, fetched her breath 
quick and short. Pulse 100, and weak — drivelling at the mouth — 
eyes protruding — vessels of sclerotica injected with blood — 
tunica conjunctiva reddened — increased lachrymal discharge, and 
a secretion of pus from the eyes — vessels of the Schneiderian mem - 
brane congested (by the bye, it is very strange that cattle prac- 
titioners seldom examine the lining membrane of the nostrils) — 
ears drooping — eyes staring, and a peculiarly dejected countenance. 
The calf had been treated by an intelligent farrier. I considered 
it incurably diseased with a brain and chest affection. In the 
cow I pronounced the disease to be in the air-passages and chest, 
and treated her accordingly, holding out to the proprietor no hope 
whatever of a cure. The cow, previous to death, dragged up her 
hind feet close to her abdomen several times. The symptoms were 
different from those of pleuro-pneumonia, inasmuch as there was 
no grunting. 
The treatment, which consisted of slight venesection at the 
onset, proved of no avail ; — spts. nit. aether, febrifuges and laxa- 
tives, external stimuli and setons. It is not advisable to subtract 
much blood in this disease, as I have tried it in others. No pre- 
ventive has yet been discovered. 
27 th instant. — Post-mortem appearances : — On dissection, the 
brain of the cow was apparently healthy — viscera of abdomen and 
pelvis likewise so : some portion of the substance of the lungs 
was congested, other parts healthy, and not increased in size. The 
air-passages, from the larynx to the air-cells, were filled with mu- 
cus and froth mixed with blood — the lining membrane of the pha- 
rynx, larynx, trachea, bronchial tubes, and air-cells, were in a 
putrid state, and emitted a noxious stench — the turbinated bones 
were quite black — the mucous membrane of the nasal passage, 
ethmoid, maxillary, and frontal sinuses, gangrenous — pericardium 
distended with extravasated blood, emphysema on its outside — 
substance of the heart highly injected — auricles and ventricles 
crammed with black blood — the valves of the right ventricle were 
in a similar state to the mucous membrane of the air-passages, 
viz. that of putrescence. 
The calf had the same appearance after death as the cow, with 
the exception of the cranium containing a large quantity of fluid, 
and an increased quantity in the ventricles of the brain. 
A few observations may not be out of place. Now, the pecu- 
liar symptoms in the calf evidently indicated a cerebral affection 
There were no particular symptoms to lead us to suppose a thoracic
