534 INFLUENZA OF A SINGULAR CHARACTER, WITH 
cases, has been to bleed if the cow was plethoric, and give pulv. 
opii 30 , in a pint of gruel; but if the animal was low in condi- 
tion, I have generally contented myself with only giving opium. 
On the 6 th of November last 1 was sent for to make a post- 
mortem examination of a fine Neapolitan boar, that had died 
suddenly, and some suspicion was entertained that it had been 
poisoned. The abdominal viscera were all in a healthy state ; 
but the stomach was full of undigested meat, while not the 
slightest mark of inflammation could be found in it : I therefore 
referred to the brain for a solution, and there, in fact, 1 found it. 
The membranes were highly congested, as well as the substance 
of the brain ; and the sinuses were all completely full, which left 
not a doubt on my mind that the patient had died of apoplexy. 
INFLUENZA OF A SINGULAR CHARACTER, WITH 
CASES OF EUSTACH IOTOM Y & TRACHEOTOMY. 
Bij Mr. J. Carlisle, V.S., Wigton , Cumberland. 
The following is a brief account of an epizootic which appeared 
among the horses of Sir Wastle Brisco, Bart., of Crofton Hall, in 
March and April last. Fourteen of them became affected by it, 
and about twenty others belonging to different people in the im- 
mediate neighbourhood. The singular character of the disease 
induces me to send you the particulars for insertion in your va- 
luable periodical. 
Symptoms . — The disease was ushered in by fits of trembling 
and rigor, the coat was staring, and there were paroxysms of cough- 
ing of an alarming nature. The muzzle was pointed forwards, 
almost in a straight line with the body. The muscles of the head 
and neck had a rigid and tetanic character. When the animal 
was made to move round the box he staggered in his gait, and, 
under the least excitement the paroxysm of coughing returned to 
a degree almost threatening suffocation. The membrana nicti- 
tans was violently thrown over the ball of the eye. The tail was 
shaking, and the fore legs abducted. He refused all kinds of 
food. The pulse varied from 60 to 80. 
About the second day large tumefactions of the parotid gland 
and surrounding parts, in a direction from the buccinator muscle 
to the nose, of a hard indolent nature, began to appear. The 
respiration was laborious at intervals, the abdominal muscles 
tucked up, and the bowels constipated ; the nostrils dilated, and 
the pituitary membrane and vascular conjunctive tunic injected.
