TRAUMATIC VENOUS THROMBOSIS.—DEATH. 
By Wm. Alston Edgar, F.R.C.V.S., Dartford. 
Subject, black mare pony, thirteen hands, five years in 
May, 1892. January 9th, 1893, called to see pony reported 
to have a swelling in throat and neck, and at 10 A.M. found 
pony in loose box on peat moss, with nose close to ground, 
and she could not be easily induced to move. A long, dif¬ 
fused swelling extended from the submaxillary region all 
down channel of neck on each side, but most intense on right; 
at lower part of neck on right side a patch of emphysema 
was present. The nostrils and lips were a little swollen, and 
also in the parotid region there was some oedema; mucous 
membrane of nostrils normal; heart rate 82, with a hissing 
sound after each ventricular contraction ; temperature 102. 2 0 ; 
respiration slightly quickened. Pony had taken a few oats 
about an hour before. 
History .—The railing around the box was about eight feet 
high, boarded, with open iron work at top for eighteen inches. 
The pony was in the habit of standing up on hind legs to look 
over top at horse in next box. A leather head-stall was 
buckled by the head strap to the top iron rail, and in jump¬ 
ing up the pony put her right fore leg through the nose piece 
and hung herself in that position, and was cut free by a boy 
who happened to be in the stable. The struggles were evi¬ 
dently severe, as a board was broken away from the side of 
the box. This happened on the afternoon of the 6th of Janu¬ 
ary. On the morning of 7th the coachman noticed a swelling 
the size of a cricket ball on the right jugular vein opposite 
the fourth or fifth cervical. In the evening the swelling had 
become flattened, and five or six inches in diameter. He now 
fomented the injured part and rubbed in a stimulating embro¬ 
cation. The pony continued to feed as usual all through the 
8th, but the swelling gradually increased but did not alarm 
the owner or attendant until the morning of the 9th, when 
it presented the appearances indicated. 
Diagnosis .—Thrombosis of jugular veins at thoracic ex-
