INFLAMMATION OF THE VEIN.

Bfid for an extent of three quarters of an inch downwards. The 
great thickening and increased vascularity of the coats of the 
vein, together with a roughened red internal surface, extended 
' three inches below the plugged part to the entrance of a small 
vein at the bottom of the neck, where they suddenly and 
abruptly terminated. The canal through this portion of the 
vessel was greatly contracted from the excessive thickening of the 
coats, but it was pervious, yet no blood had circulated through it. 
At the entrance of the branch just mentioned the coats of the 
jugular resumed their natural appearance, and the blood brought 
in by this communicating branch passed freely onwards to the 
heart. Above, the portion of vein which was plugged with 
lymph, the thickening of the coats extended (but in a much less 
degree than below) to where the jugular divides into the external 
anterior and the external posterior branches. The canal of the 
vessel through this extent was filled with coagula of blood, ad¬ 
hering somewhat firmly to the inner surface of the vein, which 
here presented a smooth appearance: these coagula extended into 
the branches abovementioned, from the divided superior ex¬ 
tremities of which they were forced in the form of plugs, by 
the mass of fluid blood accumulated beyond them.” 
Mr. Arnott’s second case is related by Dr. John Sims:—‘*A 
horse met with an accident, and w as bled on the 6th of October. 
On the 9th, a tumour, about the size of an egg, appeared on the 
wound of the vein ; matter formed, and a discharge was kept up 
from the orifice. On the evening of the 10th, a rattling noise 
was observed in respiration, and other symptoms of inflamma¬ 
tion of the lungs, attended with fever, occurred : they continued 
to increase, and resisted the remedies used for their relief. On 
the 24th, a quantity of blood flowed from his nostrils, which ap¬ 
parently came from his stomach ; and, on the 25th, he died, 
nineteen days from the time he w^as bled : he was previously in 
perfect health, except the lameness mentioned above.” Dr. 
Sims was present when the carcass was examined by Mr. Jump- 
son, veterinary surgeon, Chelsea, who saw the animal several 
days before he died. '"Eight inches of the jugular vein were 
removed : the part surrounding the orifice is ulcerated ; the coats 
of the portion of vein extending towards the head are nearly 
three times their natural thickness, and changed in colour: the 
internal coat has a dark rough surface. These changes ter¬ 
minated two or three inches beyond the orifice. This part of the 
vein contained dark-coloured pus. Immediately below the orifice 
three inches of the canal arc obliterated in a direction towards 
the heart. Proceeding downwards, the vein is quite natural, 
and contains coagulated blood.” The morbid appearances of the
