ON TORSION OF THE ARTERIES, 
FOR THE PURPOSE OF ARRESTING HEMORRHAGE IN 
VETERINARY OPERATIONS. 
« * 
By Mr. You att. 
I have since had another opportunity of putting the effect of 
torsion to the test. 
A setter was brought to my infirmary with a considerable tu¬ 
mour, which occupied the whole of the inside of the hock-joint, 
was becoming pendulous, and had two small ulcers forming on 
it. It was extirpated. It was plentifully supplied with blood¬ 
vessels, principally from the anterior tibial; two considerable 
branches of which were divided. Four turns of each with the 
torsion forceps completely arrested the bleeding, and the appli¬ 
cation of the instrument seemed to give very trifling pain. 
The bandages were not removed for four days, when the wound 
looked well, and is now nearly healed : I have, therefore, no 
doubt that torsion of the arteries will soon be established among 
us in all these operations. 
My friend and pupil, Mr. Symonds, has ere this received the 
torsion forceps which he requested me to procure for him. I 
rejoice to hear that he will avail himself of the opportunities to 
which he alludes. I will venture to say that he cannot fail of 
success, and I am quite sure that his brethren will be much in¬ 
debted to him.

From what has been stated, it must be readily allowed, that 
in a confined and ill-ventilated, stable, where the air which its 
inmates are compelled to breathe is saturated with poison, that 
this subtle fluid must be attracted into the circulation along 
with the air, mix with the blood, derange its properties, and
