COMPLETE INVERSION OF THE BLADDER IN A 
MARE. 
- Bi/ M. Gaullot, V.S, at Bar-sur-Aube, 
(Recueil de Med. Vet. Mai.) 
A MARE, aged three years, miscarried in the 8th month of 
utero-gestation. The foal was found behind her, and’a mem¬ 
branous pouch protruded from the vulva. The owner believed it 
to be a portion of the womb, and endeavoured to return it, 
but being unable to accomplish his object, M. Gaullot was 
called in. 
The protruded body, from being roughly handled, had become 
highly inflamed, and was considerably increased in bulk; and 
the membranes that covered it were become so thickened and 
hard that it was scarcely possible to imagine any cavity could 
exist within it. * 
M. G. following its apparent pedicle, could only trace it to the 
middle of the inferior portion of the vagina', and-the orifice of 
the urethra he could not by possibility discover. He therefore 
began to suspect that the protruded body was the bladder, which, 
in the throes of parturition, had been forced through the meatus 
urinarius, and inverted. 
After careful examination he discovered the orifices of the 
ureters, and on lifting with a scalpel the membranous folds 
which covered them, the urine began to flow. He excised these 
folds, and the urine regularly passed, except that, from the elasti¬ 
city of the ureters, the fluid; when the animal was walked or trotted, 
was ejected to the distance of five or six feet. 
The thickening of the bladder rendered it impossible to return 
it to its proper situation, although this might perhaps have been 
accomplished with safety before the inflammation and swelling 
had taken place; and M. G. recommended that she should be 
destroyed. The proprietor would not consent to this. The mare 
was bled, her allowance of corn stopped, mashes given, and 
fomentations used. 
Some time after (M. G. does not say how long) he was reques -
