RUPTURE OF THE COLON OF A PONY.

peculiarity attaches to these specimens, and which was also 
the case with Mr. Dickens's, namely , that the deposits of 
lymph which surround the trachea on its outer surface, extend 
thence to interior of the tube by passing between the ex¬ 
tremities of the cartilaginous rings at the superior part of the 
organ. These deposits thus, of necessity, elevate the lining 
membrane, which, together with themselves, largely en¬ 
croaches upon the calibre of the tube and mechanically 
obstructs the breathing.] 
RUPTURE OF THE COLON OF A PONY CAUSED 
BY EATING THE INTESTINES OF AN OX. 
By T. W. Gowing, M.R.C.V.S., London. 
It was reported to me on October 18th, 1858, that a pony 
had eaten what the man called a “ set/’ namely, the whole of 
the small intestines of an ox, in their raw and unprepared 
state, they not having yet been put through any cleaning 
process. The fatty matter was also attached to them. 
Some time during the night of November 2d, the animal 
voided portions of the intestines, intermingled with faecal 
matter. The part expelled was described by the owner to be 
about fifteen or sixteen inches in length, and in volume about 
the size of his wrist. 
On November 15th, the pony was supposed to have again 
eaten a quantity of the same kind of matter, as some intestines 
were missed from the tub wherein they w 7 ere kept, for the 
purpose of being prepared for sausages, &c., the man being 
W'hat is termed a gut-cleaner, or preparer of skins. 
On the morning of the 18th, the owner found the animal 
uneasy, and showing symptoms of colic. He w T as pawing 
occasionally, looking round at his flanks, and manifesting 
great uneasiness. Shortly afterwards he v T as brought to me, 
but no allusions w r ere made at that time w 7 ith reference to what 
it was supposed the animal had eaten. When I saw* him the 
symptoms did not appear to be very acute; he paw-ed w 7 ith 
his fore feet, and occasionally looked at his flanks, as before 
described. The pulse also ranged from 50 to 55, and was 
full in volume. These appearances indicating spasm, arising, 
as I considered at the time, from indigestion, I ordered a 
draught to be immediately given, composed of 
Tinct. Opii, Spt. .Ether. Nit., and Sol. Aloes. 
Between two and three o'clock the owner sent word to
