718 INFLAMMATION OF THE JUGULAR VEIN, 
2 §th. — The effects of the blister having subsided, and the vein 
being very hard, another vesicatory was put on. 
Oct. 4 th . — A tumour has been forming since the last date, and 
is getting large near to the sternum. Insert two setons in it, and 
one in the neck near to the orifice of the vein. 
Q>th . — A good deal of thick pus flows from the opening, and the 
setons discharge well; but the tumour is not diminished. 
11th . — The discharge has ceased from the orifice, which is clos- 
ing fast. The vein is hard above the orifice, but is softer below, 
and so much pain is not evinced on its being pressed. 
24 th . — The cow is becoming a great deal thinner, and has not 
fed so well lately : — the weather is cold, and appears to injure her. 
Put her up every night, and give her some hay. The wound is 
healed, but the respiration is accelerated. Pulse 80. 
27^A. — Respiration and pulse much increased. She coughs a 
great deal, and her lungs appear to be diseased. She was ordered 
to be destroyed. 
Dissection . — The whole of the vein felt like a thick rope before 
it was dissected from its situation. It had assumed the appearance 
of ligament. Its united coats, where pus was contained in them, 
were fully one-fourth of an inch thick, and its whole diameter one 
inch and a quarter. For about four or five inches from where it 
bifurcates towards the breast, it was quite solid, and obliterated. Its 
branches above were also closed, but with lymph only. From the 
lower part that was obliterated — where it was solid — for about four 
inches downwards, it would admit the introduction of a finger, and 
was filled with putrid matter. From the last mentioned part, for four 
or five inches more, a probe could with difficulty be introduced ; 
and below that it would again admit the finger. Where it en- 
tered the chest, each side of it was enlarged to about the size of a 
walnut ; one side had nearly ulcerated through its coats, and the 
other appeared to have done so, and was again uniting. It was 
quite as badly diseased for many inches into the chest, but I did 
not ascertain whether this continued quite to the heart ; yet it con- 
tained matter of the same nature as that already described. The 
internal coat of the vein, where pus was found, was of a yellow 
colour. The vein was ulcerated through in the inside of the chest, 
and the pus was making its way through on the side of the sternum,, 
and between the ribs on the near side and parts of the bones were 
bare, loose, and exfoliating, with much pus about them. The tu- 
mour near the sternum, which could be felt on the outside, con- 
tained a quantity of pus, but it lay deep. 
The Lungs were very white — perhaps, in some degree, from the 
animal having been stuck — and abscesses existed in many places. 
There were, also, many vesicles on the lungs, of various sizes, 
and some contained at least J ss. of clear serum, and appeared to be
