402 PHLEBITIS. 
formerly indicated the vessel feels hard under the skin. Supposing this 
sign to be neglected, unhealthy pus issues in quantity from the wounds 
and soils the neck. This secretion is soon converted into a dark, impure, 
and fetid discharge resembling decayed blood. The horse grows dull 
and stupid; the inflammation ultimately affects the brain, when the suf- 
fering and the life are extinguished in the violent agonies of phrenitis. 
The cure is easy, but everything depends upon the energy of him who 
undertakes it. When the lips of the wound which have been brought 
together by means of the twisted suture—as the “pin with tow wrapped 
* round it” is professionally termed—display a tendency 
to separate, and, instead of being dry, appear moist, 
let no prejudice incline toward the ancient practice of 
fomenting and poulticing the injury. Without the loss 
of a moment in hesitation, withdraw the pin; remove 
the substance which was twined round it, and apply a 
moderate-sized blister immediately over and around the 
puncture. Should the disease have ascended up the 
neck, still rub in a blister; only a proportionate amount 
ee aera of surface must then be acted upon. If the case be 
through the lips of as bad as possible, and yet the animal is alive, still a

every part the most active imagination could suppose 
to be involved. One blister, moreover, will not suffice; another, and 
another, and another must be employed, till every sign of disorder has 
vanished. They must, however, be applied in quicker succession as the 
symptoms are more urgent, while a greater interval may be allowed 
between each when the affection is less serious. In the worst stage of 
phlebitis, another blister must be put over the part upon which the irri- 
tation of the first has not entirely ceased to act. In the second stage, 
the surface must have been barely healed before another vesicatory is 
resorted to. During the primary symptom, a single application fre- 
quently is sufficient; or, at most, two blisters generally suffice. 
When the vessel assumes the corded state, a blister can effect no more 
than to check the progress of the disorder; no agency, however, which 
science has placed at the disposal of man can restore the uses of the vein. 
The vessel is lost, and lost forever. If a foul and black discharge issue 
from the openings, insert a director and enlarge the wounds, joining the 
holes by slitting up the sinuses which unite them; but do not cut the 
entire extent of the hardened vessel, as in that case you may be deluged 
in blood. The employment of the knife and the free use of blisters
