feed, separated from the stomach by a kind of constriction 
or ring formed by the muscular coat of the oesophagus. This 
was the cause of the choke for which l was called in, as the food 
massed in there and could only get into the stomach with diffi¬ 
culty. The stomach was about twice its natural size, with its 
coats very much thinner than normal. It contained a little fine 
feed and a large quantity of water. The liver and spleen were 
normal in size and shape. The liver was of a yellow color, 
easily torn and soft, while the spleen was a bright, beautiful 
green and very soft. 
The interest in this case rests in the presence of the 
pneumonia, which assumed so rapidly a very active and fatal 
issue, promoted by one or both irritating causes. First, the 
presence and size of the jabot; and second, possibly the acci¬ 
dental introduction of a small quantity of oil into the air 
passages.

CEREBRAL APOPLECTIC STROKE IN THE HORSE. 
By M. L. Magnin. 
This case being the second of the kind observed by the 
author in six years’ practice, that fact has led him to the con¬ 
clusion that the accident is one of no uncommon occurrence. 
A mule, while being exercised in a ring, jumped over an ob¬ 
stacle scarcely three feet high, and instead of alighting on his 
fore feet, fell forward on his head, striking the ground with 
the superior part of the skull, and then, making a complete 
summersault, died instantaneously. 
The post-mortem showed no indication of any fractures, 
complete or incomplete ; no ecchymotic spots appeared in 
the subcutaneous cranial cellular tissue ; and the meninges 
had a normal aspect. But on the floor of the fourth ventricle, 
towards the right corpora recti forma, appeared a rough and 
irregular longitudinal laceration, with an ecchymoscd 
border, beginning near the calamus scriptorius, and ending 
in front of the mezzocephalon; narrow behind, it increased
