examination the intestines appeared healthy, but on removing the 
head a large quantity of serous fluid poured out from the brain 
cavity, the brain was unusually firm, and the blood-vessels at the 
base thoroughly arborescent; in the lumbar vertebrae there was 
also found a quantity of serous fluid. Mr. Roalfe Cox had 
previously attended the same horse from injury between the hair 
and hoof, and an escape of synovia therefrom; at this time the 
animal was addicted to snapping and quietly walking round his 
box, which ceased when oil and turpentine were administered. 
The present case, one of cerebro-spinal disturbance, occurred in a 
thirteen-years old drayhorse first noticed to be standing calm 
and motionless in his box, breathing slowly, and the pulse normal; 
he then walked quietly to the stable door, where he stood as 
though fixed, blows having no effect upon him; eventually was led 
to his box, when he commenced walking round to the left in a 
methodical manner. In the morning he was roaring loudly, when 
the poll was rubbed with turpentine and a tracheotomy tube in¬ 
serted, after which he gradually recovered and worked for four years 
longer and was then destroyed on account of his old age. This 
case of catalepsy (so designated) is the more remarkable owing to 
recovery on the treatment of one of the symptoms and that 
secondarily. 
Another case instanced occurred in a dray horse the subject of 
hemiplegia of the right limbs. The horse was slung, but treat¬ 
ment proved ineffectual. In the 'post-mortem examination a large 
clot of blood was observed in the base of the brain. 
Another case was related of a horse reported as stiffnecked, 
which was treated as a rheumatic affection, recovered ; some time 
afterwards, when in harness, commenced reeling about, was 
obliged to be led home, when he recovered; the symptoms recurred 
again and again, but subsided when the horse was taken out of 
harness. The horse died from an attack of paralysis, and an ex¬ 
amination was instituted, when the upper part of the atlas was 
found to be drilled through by absorption, and an abscess had 
burst through the theca vertebralis on the spinal cord; this ex¬ 
plains the quick recoveries after removal of the harness. 
Another case .—A horse suffering from a cough and making a 
roaring noise, which was aggravated by water being offered; the 
operation of tracheotomy was commenced, when the horse fell 
forwards, and before assistance could be rendered died from 
asphyxia. It was found that the posterior half of the whole 
length of the trachea was separated, and narrowed by about one 
third, and the separated part between the membrane and car¬ 
tilage filled with soft pasty effusion; there was no congestion 
noticed. 
Mr. Burrell related a case where a horse became violently ex-
