692 RUPTURE OF I MK POSTKRIOR AORTA IN A BLIND MARE. 
granular structures were at ail diseased; but the tongue was 
indurated and dry throughout; in fact, it was almost petrified : 
no fluid existed in it of either serum or pus. I am inclined to 
say it was a dry cancer, and must have existed some considerable 
time. 
Should I have any case in future in my practice worthy of in- 
sertion, I shall be always at my post. Wishing your Journal 
more extended support,

A CASE OF RUPTURE OF THE POSTERIOR AORTA 
IN A BLIND MARE, AND SINGULAR STATE OF 
THE EYES. 
By Mr. T. Swarbrjck, V.S., Skipton , Yorkshire. 
About eight o’clock a.m. on the 21st September, I was called 
to attend a blind post-mare, the property of Mr. Bradley, of the 
Devonshire Hotel here, the man saying she was griped. 1 went 
immediately, and found her rolling about, sweating a little about 
her neck and flanks, and, if kept up, pawing with her off fore- 
foot. The pulse 65, and small. She had been off work a few 
days, on account of a crushed heel, and had been turned out in 
the field. 
I administered the common gripe mixture, the ol. lini, tinct. 
opii, and sp. aether, nit., and ordered her to be well cleaned over. 
9 a.m. — Much quieter. Pulse 85, but quite imperceptible at 
the jaw. 
I began to suspect some intestinal lesion, and that the case 
would terminate fatally. 
II a.m.-- Much worse. Rolling about, and beating her head 
against the floor and manger. I gave a draught of tinct. opii in a 
little warm water, and she drank some chilled water. Pulse 
small, intermittent, and about 90. 
Half past 12 p.m. — Has fallen twice, and appears likely soon 
to die. 
Half past 1 p.m. — Dead. 
Post-mortem i, 2 hours after death . — The thoracic viscera per- 
fectly healthy. The stomach and intestines contained little food, 
and appeared quite free from disease. The cavity of the abdomen 
was filled with blood, partly fluid, and one large clot about twice 
the size of an ordinary pail. I examined carefully for the lesion, 
and, to my surprise, found the abdominal division of the poste- 
rior aorta ruptured, about one inch posterior to where are given
