tion, or whether because applications too irritating have been 
made across the track of the indurated vein, inflammation rises too 
high, the suppuration of the clot is eflected, and an abscess formed 
in the interior of the vein is not slow in finding an issue outwardly 
through the orifice effected in the bleeding. In this case, as we 
have said before, the obliteration of the vein being effected in the 
very branches of the jugular, there is no hsemorrhage to fear, but 
an obstinate fistula at the place of the abscess, throughout the 
whole extent of the vein, and lasting until the exfoliation of the 
internal membrane is completely effected. Finally, who has not 
been struck with the frequency of those haemorrhages which mani¬ 
fest themselves so often in consequence of thrombus in horses out 
of condition or of weak constitution] 
The indications of treatment which result from this anatomical 
study of the phenomena of inflammation of the jugular vein are 
simple, and easy to be understood. 
At first, the flowing of the blood and the contact of atmospheric 
air are effected by the application over the tumour of the thrombus, 
if such should exist, of a pledget covered with blistering ointment, 
or a bandage mingled with powdered cantharides, which is very 
efficacious in producing this double result. Afterwards, when in¬ 
flammation is developed, it is moderated by the continuous employ¬ 
ment of emollient applications. Then, when the induration is 
formed, the application of irritants or of the cautery over it, in 
order to produce its absorption. 
If fistula exist, following the track of the vein, some stimulating 
fluids may be injected, or a seton may be passed to destroy the in¬ 
ternal membrane, imperfectly organized, and which must exfoliate 
before cicatrization can be effected. Such are the simple means 
which it will generally be sufficient to adopt in order to bring 
about the cicatrization of the vein. 
The ligature of the jugular, which has been advised in case of 
obstinate haemorrhage through a considerable orifice, is a measure 
too often unsuccessful for us to think it necessary to dissuade the 
surgeon from having recourse to it. 
The principal cause of the little efficacy of that operation con¬ 
sists in the inflammation, which renders the walls of the vessel so 
friable, that the ligature is soon disengaged, and thus permits the 
disorganizing action of the air upon the clot.
