REPORTS OF CASES. 
The horn penetrated the skin just inferior to the groove 
containing the artery, vein and nerve, about fourteen inches 
posterior to jaw, and with an upward, rotary movement divid¬ 
ed the vessels and lifted a portion of each from their place. 
About ten inches of the carotid artery, divided anteriorly 
to the wound, was left hanging, ten or twelve inches of the 
pneumogastic nerve divided posteriorly to the wound, and 
live or six inches of the jugular vein divided posteriorly to 
the wound, were in the same condition. 
The artery, from the straining and tearing of its walls, 
immediately plugged itself, but from the vein the hemorrhage 
was profuse. The owner of the horse was at hand, but could 
not get to it until it sank down, and then grasping the divided 
end ligated it with a thread. 
I was immediately sent for, and on arrival, some thirty 
minutes later, found the colt again on his feet, but very weak, 
respirations quick and shallow, the eye on side of the injury 
was closed, and no effort or no power to raise the lid. 
After using some stimulants internally, I drew the blood 
vessels out until their walls seemed healthy, and ligated them 
with carbolized catgut, cut off the injured portion, two inches 
of the artery and nerve, six of the vein, and after suturing the 
outside wound with silk and using carbolized dressing healed 
nicely. 
1 have had frequent opportunities of examining the colt, 
which is now over one year old, and seems to enjoy as near 
perfect health as any other animal; runs as fast and plays as 
much, and with as little fatigue as any other colt in the pas¬ 
ture ; manifests no inconvenience from the accident or its re¬ 
sults. The eyelid still droops somewhat, and the side of the 
head is not developed in proportion to the other. The pulse, 
as noticed in the sub-maxillary artery, lacks in volume on this 
side. 
The respiratory sound in the lung and on the injured side 
has gradually weakened from the time of injury, and at pres¬ 
ent very little, if any, murmur is audible. The murmur in the 
opposite lung is very loud, and it is impossible to determine 
whether the slight sound noticed on the injured side comes
