INTRO -SUSCEPTION OF THE ILEUM. 
On examination, I found her a confirmed roarer, and was in- 
formed that she had been bad about two years, and was now in 
such a state that the owner thought of destroying her. 
I proposed the operation of tracheotomy, to which she con- 
sented. I introduced into the windpipe a tube resembling that 
generally used, which gave immediate relief. The tube is com- 
posed of double block-tin, and is changed every third day. 
After a few days’ rest, the mare resumed her work, even going 
long journies without any apparent inconvenience. She has 
been doing regular work ever since the operation, and gaining 
flesh as fast as she had previously lost it. 
A CASE OF INTRO-SUSCEPTION OF THE ILEUM. 
By Mr. J. Dunsford, London. 
December 10 th, 1840. — A bay carriage-horse, aged, was at- 
tacked with slight catarrhal fever, sore throat, and cough, appa- 
rently unattended by any thing peculiarly dangerous. Laxative 
and fever medicines were given. 
1 1th . — The horse appears to be doing well — continue fever 
medicine. About one o’clock at noon the animal suddenly hung 
back, broke his halter, and manifested the most acute pain. He 
was immediately sent to our stables, and the most active antiphlo- 
gistic treatment adopted without the least alleviation of pain. 
He lay down, rolled on his back, and continued in this position 
for five or six minutes. Immediately afterwards he would sit on 
his haunches, repeatedly gazing first on one side and then on the 
other with an inexpressible look of intense agony. A profuse 
perspiration broke out several times. The faeces were at first 
voided in small quantities, and repeated two or three times. The 
pulse was not at ail affected in quickness or character for two or 
three hours, and then it suddenly became more rapid and indis- 
tinct. The respiration was less disturbed than might be expected 
from such intense agony. 
These symptoms continued during eight hours, with little or 
no variation, and there were evident signs of approaching disso- 
lution. Two hours afterwards death ensued. 
Post-mortem Examination . — On opening the abdomen, the pe- 
ritoneal coat of the large and small intestines exhibited consider- 
able inflammation, but more especially the caecum and ileum,
