AN ACCOUNT OF CERTAIN ABNORMAL FORMATIONS 
FOUND IN THE BRAIN OF AN AGED PONY. 
By Mr. HA.YCOCK, Veterinary Surgeon , 
(Member of the Veterinary College, Edinburgh) 
Huddersfield. 
The following case I have deemed worthy of record, simply 
from the fact of abnormal formations existing in the lateral ventri- 
cles of the brain during life, without giving rise to any manifest 
disease, or derangement of function of any kind, in the animal in 
which I discovered them. 
In order, therefore, to give the reader clear ideas of the case I 
am about to describe, I will first relate such particulars respecting 
the animal as will enable him to do so in every essential. The 
subject of this case was a pony, the property of a gentleman re- 
siding in this town. The animal was fourteen hands high, of a 
bay colour, of the cob breed, and at least eighteen years of age : he

animal ever known to be affected with illness. On the 8th of 
November, 1847, it was deemed necessary to clip the animal, and 
at night, after the operation was performed, he was taken out of 
the stable to be smartly galloped ; and when returning home again • 
he was accidentally run against by a horse and truck, the shaft of 
which pierced his side, fracturing three ribs, and inflicting such 
other injuries as to cause death in about two hours afterwards. 
Examination twelve Hours after Death. 
State of the lungs , heart , fyc. — The contents of the chest were 
perfectly healthy. The lungs did not exhibit the slightest trace of 
disease; the heart was also sound and firm in structure, and weighed 
seven pounds avoirdupois. 
State of the digestive organs. — The abdominal cavity contained 
a large quantity of liquid blood, in which was mixed faecal matters, 
that had escaped out of the colon from a large opening or rent 
caused by the shaft of the truck lacerating it, when the concussion 
took place : otherwise the bowels and stomach were perfectly
