DEATH OF A FILLY CAUSED BY AN ENORMOUS 
TUMOUR GROWING IN HER BELLY. 
Case sent by Mr. SlMMONS, Thame. 
A MARE, two years old, the property of Mr. King, of Crendoz, 
Bucks, was observed to be very uneasy on Thursday last, when 
the smith of the village was sent for, who gave what he called “ a 
fever-ball and clyster,” and bled the mare. She not being relieved, 
I was sent for the evening of the same day. I found the mare with 
a pulse about 70; the artery being so tense that it was difficult 
to feel the pulsation. They could give no account of any dung hav- 
ing been passed for a day or two. There existed violent palpita- 
tion of the heart, so much so, that it might be heard outside the 
stable. She kept in continual motion, often lying down and quickly 
rising again, but not in the hurried manner of a horse with colic ; 
in fact, she seemed in but little pain, though she at times pawed 
up the litter and hung down her head, with her eyes almost closed, 
like a horse with staggers. Her breathing was very laborious. 
In the first place I bled her, and administered ol. lini, aloes, and 
sp. eeth. nit., and clystered her. From this she appeared for a time 
relieved ; but not the least portion of dung came away with the 
clyster fluid. In an hour the same uneasiness re-appeared, but 
without the laborious breathing or palpitation ; the pulse still be- 
ing at 70, and remaining about the same the whole of the night. 
The next day, however, the pulsations at the heart became very 
feeble ; in fact, it appeared an irregular fluttering pulsation at the 
side. I administered more aloes and oil, and repeated the clysters 
every four hours, the water returning in every case without the 
least portion of dung. 
She appeared to be getting much weaker, but still exhibited 
no acute pain. 
In the night she dropped down, and died without a struggle. 
On opening her, the first thing to be seen was an immense 
solid mass of a cancerous appearance, weighing twenty-six pounds 
and a half, growing between the bowels, occupying the situation
