DISUNION OF THE LAMINAE OF THE FOOT. 
uterus was ruptured as well as the diaphragm ; and if she 
had been bred from before that, the fractures of the ribs might 
have been caused by the violent action of the intercostal 
muscles in parturition. 
We need not remind our readers, that when they meet with 
a case of ruptured diaphragm, they are not to take it for 
granted that it was the cause of death. In the majority of 
instances it is probably produced by the convulsive struggles of 
expiring life. It may even occur after death, if the animal be 
' not opened until several hours have elapsed. 
The symptoms of ruptured diaphragm are exceedingly ob¬ 
scure. There are none on which the surgeon can depend. 
This, however, is a matter of little consequence. A consider¬ 
able rupture is almost necessarily mortal, from its admitting 
the abdominal viscera into the thoracic cavity, and thus ren¬ 
dering respiration difficult or impossible. When the lesion 
has been small the abdominal viscera, have insinuated them¬ 
selves into the aperture, and a fatal hernia has resulted. ^

DISUNION OF THE LAMINiE OF THE FOOT. 
[J5j/ the same,^ 
MR. COLEMAN, I am informed, has asserted that the 
shoulder of a horse, whilst living, may sooner be pulled from 
the body, or one limb from another, than the laminae of the 
foot can be separated by any force that can be applied; and 
that it is an utter impossibility to separate them : but the fol¬ 
lowing case is not consistent with that opinion. 
CASE. 
A pony abdut 12 hands high, the property of Mr. Franklin, 
Innkeeper, Oswestry, was put into a small cart to be broken ^ 
for draught. Something frightening him, he ran away, and 
,came in contact with a waggon that was going along the road ; 
his fore-foot was wedged under one of the wheels, and in try-, 
ing to extricate himself, he pulled his foot (with the exception of 
about half an inch of the anterior part of the coffin bone) clean 
out of the hoof, and which was as clearly separated as if it had 
been macerated in water. His foot bled a great dealy and the 
coffin bone was fractured into three pieces. He was destroyed.
