PROTRUSION AND INVERSION OF THE BLADDER. 639 
ward accident happened to her afterwards, and she was sold, four 
months subsequently, at the fair of St. Loo ; after which the 
owner lost sight of her. 
I would observe, that this reduction was accomplished much 
more easily than I had supposed that it would have been, and 
without any injury to the neck of the bladder. 
Protrusion and Inversion of the Bladder, with 
Amputation of that Organ. 
By M. Lecoq. 
On the 7th of May 1831, 1 was desired to see a draught mare, 
seven years old, that was about to foal. The usual precursors 
of that act had appeared, and seemed to announce a difficult 
parturition. In the mean time she was intrusted to the care of a 
young man inexpert in the veterinary art. After a protracted 
labour, she was delivered ; the after-birth soon followed, and 
she appeared to be doing well; but, without the slightest warn- 
ing, a round dull-coloured body, as large as a double fist, pre- 
sented itself at the orifice of the vulva, and appearing to be a 
portion of the vagina. This frightened the young apprentice, 
who then had recourse to M. Dufour, of Cerisy. 
He saw her at eight o’clock in the morning. A dull-coloured, 
fleshy, pyriform body, as large as a three-pint bottle, and eight 
or nine inches in length, presented from between the lips of the 
vulva. It was soft, and its surface presented no irregularity, 
but some small transverse rugae. On the hand being introduced 
into the vagina, it was evident that this body was continuous 
with it. On separating the leaves of the vulva, on the upper 
surface of this body, and at a little distance from each other, 
were two small nipple-formed bodies, of the size of a pea, and 
from the centre of which, at every effort made by the mare, a 
slightly coloured fluid was projected. He recognized in them 
the ureters darting out the urine, and, consequently, the tumour 
was the bladder turned inside out. 
The first indication was to return it to its natural situation and 
state. To accomplish that, it was necessary to put the mare into 
a trevis, and to place her with her foreparts lower than her 
haunches. After vain and long-continued attempts, we found it 
impossible to effect a reduction of the prolapsus : the struggles 
of the mare — the constriction and engorgement of the sphincter, 
and the thickening of the parietes of the bladder, presented insu- 
perable obstacles. M. Dufour then informed the owner of the 
danger in which the mare was, and induced him to send for me.
