312 FRACTURE OF THE ISCHIUM—CORDS IN CATTLE. 
stable. I was sent for to examine him ; he was four years old, 
had very clear legs, and excellent feet. I told the owner treat¬ 
ment would be of no avail; but he was determined to have all 
four legs blistered : it was done, the horse was turned out to 
grass for two months, and came up perfectly sound. The weather 
soon afterwards became verv wet and cold ; the horse became 
lame ; in fact, the disease seemed to be entirely influenced by the 
changes of the atmosphere. Thus, in the summer, a horse of 
this description will be mostly sound, whilst in the winter he 
will be generally lame. I merely mention this as being a well- 
marked case, but have seven or eight others which I could re¬ 
late if necessary. 
A CASE OF FRACTURE OF THE ISCHIUM. 
By the same . 
The subject of this was an aged mare that had worked as off 
leader in the London mail, which passes through this town ; the 
distance she ran was only five miles a day. The other morning, 
about half a mile from the end of the stage, the coachman per¬ 
ceived her (as he said) to falter; he immediately stopped the 
coach, had her removed, and led to the stable. I was sent for ; 
but although not ten minntes’ walk, she fell down and died before 
my arrival. There was a great quantity of blood escaping 
through the vulva, and a few small pieces of bone, which 
convinced me that some part of the pelvis was fractured. On 
examination, I found the ischium shattered into several pieces : 
the fracture extended through the foramen obturatorium, so that 
the two bones were completely severed asunder, the divided ends 
of which had lacerated the bladder and uterus. There w T as 
upwards of a gallon of blood, mingled with urine, in the cavity 
of the abdomen. This fracture, I think, could not be produced 
by the muscular exertion of the animal. The coachman, in my 
opinion, must know more about the matter; but, unfortunately 
(as is too often the case), the practitioner cannot always trace 
these occurrences throughout.

As regards a complaint called the cords in cattle, described by 
Mr. Corbet, in your last, I have a work in my possession called 
the Repertory of Arts and Sciences, published in 1795, wherein
