258 CONTRIBUTIONS TO VETERINARY PATHOLOGY. 
stantly with him, thrusting tow into the opening, to arrest the 
haemorrhage. At last he was left alone, and was soon after- 
wards found dead. 
The autopsy disclosed an extensive laceration of the lower 
part of the left jugular vein, extending into the anterior vena 
cava, at the point of the termination of the former into the latter 
vessel. A cavity containing a large mass of partially decom- 
posed coagulum existed, connecting the external tumour with 
the ruptured vessels. Quantities of coagulated blood were 
found between the interstices of the subjacent muscles. 
Abortion in a Mare succeeded by acute Laminitis . 
(Sixth Contribution.) 
The subject of this case is an aged mare, the property of a 
carter living in Heigham. I was passing his house on the 
evening of the 27th of March last, and was called in to see her. 
She had been working in the morning, though found shewing 
some symptoms of uneasiness towards noon. It was supposed 
to be colic. She was taken to the stable, and soon lay down in 
her stall, and, whilst her owner was gone to fetch her some 
water, passed a dead foal, apparently about six weeks before its 
proper time. When 1 saw her, there did not seem to be much 
amiss. The pulse was hard, and about 50 ; she was inclined 
to eat, and appeared as comfortable as, under existing circum- 
stances, could be expected. Aloes 3yj were administered. 
She fed well during the evening, and was left at midnight in a 
satisfactory condition. 
As a similar case has recently been published in your Janu- 
ary number, by my friend Mr. Gloag, I shall not enter into the 
details of this, but will merely observe that, on the following 
morning, acute laminitis had set in, accompanied by the most 
distressing symptoms. The pulse was varying between 90 and 
100, scarcely to be counted, a quivering at her flanks, inability 
to move at all, appearing as though paralysed. The heat in all 
her feet was intense, and her respiration was much accelerated. 
I had on my first visit made inquiry regarding the foetal mem- 
branes, and was informed they came away with the foetus. This 
morning another small portion, however, was passed. I ex- 
amined her per vaginam, but could detect nothing wrong save 
great distention of bladder. She appeared unable to discharge 
her urine, and this increased her uneasiness. I introduced the 
catheter, and a very large quantity of water came away, which 
evidently gave her ease. 
Her bowels were remarkably torpid : they were never acted 
upon so as to produce softened faeces, although she had taken at
