382 INVERSION OF THE BLADDER IN A MARE. 
ed again to visit her. The bladder was how insensible to pressure, 
diminished in size, and a brown colour had succeeded to the in¬ 
flammatory redness. The ureters continued to discharge the water 
in jets, less strong and more frequent, and evidently furnished as 
much urine as the bladder would have done in its natural state. 
M. G. again recommended that she should be destroyed. I 
will not consent to that yet,replied the owner; but you must cut 
off this protrusion.’^ It was in vain to remonstrate. The bistoury 
and hot iron were resorted to, and the bladder was amputated, not 
at its neck, but an inch below the insertion of the ureters, and 
still leaving one-third of it protruding. Very little haemorrhage 
followed. No inflammation supervened; and in a few days the 
part which remained had very considerably diminished. It scarce¬ 
ly projected from the vulva. The ureters no longer expelled the 
urine by jets, but in an almost continuous manner. In process of 
time the remains of the bladder diminished to the size of a nut, 
and were concealed within the vagina. The urine was now dis¬ 
charged in the vagina; and flowing to the anterior part, there 
formed a kind of dilatation or reservoir, which could contain the 
urine excreted for four hours during rest, and for one hour while 
the animal was at work. When the mare wished to urine, or 
or to empty this reservoir, she placed herself in the same attitude 
, which she had previously been accustomed to assume; but the 
urine, instead of being rapidly evacuated, ran slowly over the 
thighs and legs, and produced loss of hair and much soreness 
and erosion. 
The owner worked her four years after this, and then sold her; 
and M. G. was afterwards unable to trace her. 
No English writer gives any account of this singular inversion, 
nor has it fallen within our experience or knowledge. M. 
Gaullot’s memoir, therefore, will be interesting to our veteri¬ 
narians. 
Considering the bulk of the bladder, and its attachment to the 
pelvis and the vagina, by cellular substance and by the ligaments, 
or, more properly, duplicatures of the peritoneum, and by the 
urochus at its fundus, we should have thought it impossible 
that this viscus could descend through the female urethra, even 
short, and .straight, and dilateable as it is. The inversion can 
only be effected during the violent throes of a most laborious 
parturition. 
Since, however, the bladder may, although very rarely, be in-
