INFLAMMATION OF THE VEIN. 
chest and other viscera are then given in support of Mr. Arnott's 
opinion, that phlebitis induces a secondary constitutional affec¬ 
tion, which is the cause of death, and not by direct extension of 
the inflammation of the vein. 
A year and a half ago I was desired to attend a two-year old 
thorough-bred filly, the property of W. Ormsby Gore, Esq., 
M.P.: she had an inflamed vein after being bled; the hard, 
corded, tender state of the vein extended two or three inches on 
each side of the orifice, with slight swelling of the parotid gland. 
I did not consider the case as very severe, and felt no alarm be¬ 
yond the probability or, indeed, almost certainty, of losing the 
vein on that side. The filly appeared in health, and had been 
bled by the groom more as a part of stable discipline than that 
she^ was supposed to be labouring under any disease. For six 
days every thing appeared to go on well, and the inflammation 
in the vein was arrested ; it was, however, evident that the 
cavity of the vein was plugged up and impervious to the passage 
of the blood. At this time some unpleasant symptoms began to 
shew themselves; there was every reason to suspect mischief in 
the chest, but it was not easy to say precisely what that mischief 
was. There was no apparent extension of the inflammation of 
the vein down the neck to the chest. I, therefore, considered it 
as sub-acute inflammation of the lungs, and not connected with 
the inflamed vein, and treated the case in the manner that 
I considered the circumstances required, but without success; 
for, in ten days from the time the internal affection was 
observed, the filly died. The vein, for about two inches above 
and two inches below the orifice, was completely obstructed; 
the coats of the vein being inflamed and thickened, and the 
caliber of the vessel filled with condensed coagulable lymph: the 
disease of the vein appeared to extend but little, if any, beyond 
this obstructed part in either direction. Above, the vein was full 
of dark-coloured blood ; below, it was quite empty, and exhibited 
no morbid appearance, and was quite pervious. At the point where 
the puncture in bleeding had been made, there was a cheesy sort 
of substance intermingled with the condensed lymph. The peri¬ 
cardium was inflamed, and there was effusion of a reddish serum 
within its cavity; the lungs were inflamed, but not disorganized ; 
there was effusion in the chest, but not great in quantity; the 
pleura was also in an inflamed state. It being a wet, cold day, 
and the carcass in the open air, no further examination was 
made. I must repeat, that, at the time this case occurred, I did 
not consider the disease in the chest as connected with the in¬ 
flamed vein, although 1 had seen Mr. Arnott’s paper previously. 
I am now, however, of a different opinion, and cannot help
