SUBMUCOUS HEMORRHAGE IN THE INTES¬ 
TINES OF A HORSE. 
By Professor Brown. 
In the course of his investigations the pathologist often 
has to rest satisfied with a bare record of facts, which are 
quite inexplicable by reference to the evidence with which 
they are accompanied. Certain morbid changes in the 
organism are observed*, and the natural inquiry is. What 
caused them ? Probabilities present themselves, and are 
tested, but fail to furnish the clue to a solution of the 
enigma, and the investigator is at last forced ta admit that, 
notwithstanding the definite character of the results, their 
origin is mysterious. 
The case which suggests these reflections also in itself 
affords a good illustration of their truth; a horse is suddenly 
attacked with abdominal disease; in the course of a few hours 
he dies, and a post-mortem inspection shows that very intense 
action, of a destructive kind, has been going on. Inquiry is 
made, but no evidence is obtained to account for the unusual 
morbid appearance. The animal was placed under perfectly 
favorable conditions; everything in relation to the system of 
management which was adopted while the horse was in his 
owner^s possession was quite in the usual course; and until 
the morning of the fatal attack the animal had not given 
evidence of any important derangement.
