quiry, to elicit the cause. The only way in which I could account 
for his attack was the probability of his having been over driven!; 
however, he was found in the morning with his head stretched 
out, ears and tail erect; in short, decidedly tetanic. My assistant 
saw him first, and bled him copiously, and with difficulty got a 
ball down containing eight drachms of aloes and one drachm of 
calomel. We emptied the rectum by means of clysters, which were 
repeated frequently until the ball operated, which it did in the 
course of the night in a sligh t degree : I then continued to give small 
doses of aloes and opium, keeping up a perpetual blister on the 
throat, and in about three w r eeks he was sold at Morris’s; and I 
have seen him about the streets perfectly well several times since.

The Veins of the Nose. — The Schneiderian membrane being so 
plentifully supplied with arterial vessels, the veins are propor¬ 
tionally numerous and large. They do not, however, pursue 
their course in the usual manner, but are continually running into 
sinuses, and particularly on the lower part of the nasal cavity, 
and on the inferior turbinated bone. This accounts for occasional 
haemorrhage from the nostril of the horse from very slight causes, 
and for the difficulty of arresting it. A sinus, or reservoir of 
blood, so superficial and ill defended, is easily ruptured, and, 
there being little contractile power in such a vessel, the orifice is 
with difficulty closed. 
Spontaneous Hemorrhage from the Nose in the Horse. —The 
horse is more subject than any other domesticated animal to 
epistaxis, or spontaneous haemorrhage from the nostril, and the 
discharge of blood is sometimes very great. The bleeding is with 
great difficulty arrested, and the habit of recurrence is too easily 
formed. The application of cold is usually employed to stay the 
bleeding, but generally without success. The nasal cavity is 
large, and it is difficult or impossible to discover the precise spot 
from which the haemorrhage proceeds. I have employed water 
artificially cooled to some degrees below the freezing point, over 
the whole surface of the nasal and superior maxillary bones, and 
that until I was heartily tired of it, and my hands were almost
