INVERSION OF THE BLADDER. 
501 
We have also experimented on the dog, with the same pre- 
caution of filtering the pus before the injection, and we have pro- 
duced a disease of the lungs very much resembling that of the 
human being that had been destroyed by glanders. The nasal 
cavities, throughout their whole extent, were the seat of the most 
acute inflammation. At the lower part of the septum, on the 
left side was a black spot, softened and ulcerated. After these 
facts, and others which have been published in the Recueil , is it 
too presumptuous or too soon to conclude that glanders is pro- 
duced by the presence of pus in the circulation ? Sometimes even 
in the human being it is developed spontaneously in purulent 
fevers, which clothe themselves with the character of acute mange 
and acquire these virulent properties, without its being necessary 
to trace it back to contact with the glandered horse, in order to 
explain the development of this strange disease.

CASE OF INVERSION OF THE BLADDER DURING 
PARTURITION, AND EXCISION OF A PORTION 
OF THAT ORGAN. 
By M. Canu, Fere, Thorigny. 
On the 25th of May 1815, I was requested to see a mare, 
suffering severely from laborious parturition. I found her lying 
on her leftside, covered with perspiration, and her labour pains 
frequent and violent. The proprietor had rendered her his assist- 
ance, and the foal had lived about half an hour; but the mare 
had suffered much before she was relieved. A large portion of 
membrane which hung from the vulva made me suspect that 
there was inversion either of the vagina or the uterus. The 
proprietor told me that he had long attempted in vain to replace 
it. I examined her very carefully, and, not being able to satisfy 
myself to what organ it belonged, I caused her to be lifted up. 
This was accomplished with difficulty, for she could not stand 
without support. She was, however, making continual attempts 
to expel this substance, and in so doing her urine was propelled 
to a considerable distance. 
I was far from suspecting inversion of the bladder, never 
having met with it, or heard of its occurrence in veterinary 
medicine. The stable was dark. I ordered a candle, and then, 
separating the lips of the vulva, I could see to the bottom of the 
vagina. Every thing appeared to me to be in its place, and I 
began to suspect inversion of the bladder, although 1 could 
scarcely believe the possibility of it. I then traced the inferior
