REPORTS OF CASES. 
On admission, the body was partially covered with sweat, 
slight colicky pains, pawing occasionally and making frequent 
attempts to lie down, elevating and switching the tail, fre¬ 
quent and violent straining, with legs widely stretched apart, 
arching of back and using extraordinary efforts of the abdo¬ 
minal muscles in trying to get rid of some foreign body from 
the vagina, anxious countenance, pulse accelerated and respi¬ 
ration jerky in character. At each effort of tenesmus, the 
vulva would dilate and a bright rose colored looking tumor 
of globular shape would protrude from the vulva, and at the 
same time a few masses of feces were expelled from the rec¬ 
tum with a considerable amount of flatus. Thinking it a case 
of prolapsus of the uterus, and having her properly secured 
in the standing position, made a vaginal examination, and to 
my surprise found a complete inversion of the bladder, which 
was easily reduced on account of an excessive dilatation of the 
meatus urinarius, which was about two inches in diameter, soft 
and flabby to the touch. The mass was no sooner reduced than 
it was expelled again, from the constant and violent muscular 
action; five or six times it was replaced and as fast returned 
again. At last I determined to hold it in place with my hand 
in the interior of the bladder, acting as a pessary, but the ef¬ 
forts on the part of the mare to evert the bladder and resist my 
hand by her persistent straining, were so violent that a metal¬ 
lic female catheter was introduced into the bladder and held 
in position by Dr. Hiihne, one of the staff of the hospital, and a 
solution of one ounce each of tincture of opium and belladonna 
was poured into the bladder through the catheter. In about 
five minutes the tenesmus lessened, but on withdrawing the 
hand, the whole contents of the bladder was violently expelled, 
mixed with a small amount of blood, and the bladder itself 
partially inverted. The same method of reduction was em¬ 
ployed again and the same amount of opium and belladonna 
introduced, which resulted in reducing the irritation. In the 
meantime ten drachms of chloral hydrate in pill form was 
given, which had its effects in twenty minutes, and all efforts 
at expulsion ceased. 
I was about preparing some sort of a pessary to strap in
