space for the blood to insinuate itself into the cellular 
tissue; or working the horse immediately after the opera¬ 
tion ; or neglecting to tie up his head for a short while after 
bleeding to prevent his removing the pressure of the pin 
from the wound, by rubbing his head against the manger; 
and other causes. 
Symptoms. —The edges of the wound having separated, 
or being ragged, from the clumsiness of the operator in not 
penetrating the vein at the first blow, become swelled and 
inflamed, and discharge a thin fluid of a bloody appearance. 
In a day or two this will put on the form of matter. In¬ 
flammation to a considerable extent may ensue, with 
swelling of the muscle, and the vein will become hard, and 
feel like a cord, and increasing upwards, the contiguous parts 
will feel very hot. This is generally followed by a series ol 
small abscesses over the seat of the wound. The cordiness 
of the wound gradually increases still further upwards ; and 
from the inflammation also following that direction, it fre¬ 
quently proves fatal to the horse. 
Remedies. —Some veterinary surgeons, to stimulate the 
part, apply a hot iron to the margin of the orifice, which 
induces a union of its edges. Should this not prove 
effectual, and if the swelling is great and the abscesses have 
made their appearance, the next remedies are to inject a 
weak solution of nitrate of silver or other caustic liquid 
into the abscesses, or to introduce setons into them; and 
should this fail, he should cut out the diseased portion of 
the vein. 
This operation will not be attended with any bad conse¬ 
quences ; for all the blood-vessels, whether veins or arteries, 
communicate with each other either directly or indirectly,, 
in so many different ways, that an injury sustained by a 
portion of them is compensated for by the current of the blood
