BY AN OSSEOUS TUMOUR. 359 
morning the animal, who had passed his urine several times 
without difficulty, appeared to be in a comparatively satisfactory 
state. He was yet, however, considerably disspirited. He did 
not eat any thing, and he drank very little. 
The same treatment, with the exception of the bleeding, was 
pursued during some days. No sensible alteration of symptoms 
occurred ; but the horse remained in nearly the same state until 
the 31st of July, when haemorrhage took place on the internal 
surface of the intestine, and the faeces became liquid and mingled 
with a considerable quantity of blood. 
Having communicated to the proper officer my fear as to the 
result of the case, since these new symptoms had appeared, M. 
Bouley, Jeune, in quality of his situation as veterinary surgeon of 
the gendarmerie of the Seine, was sent for. This gentleman, 
being confined by illness, could not attend until the 3d of 
August. 
The patient was then sadly enfeebled by a violent diarrhoea, 
black and fetid, containing clots of decomposed blood. The 
pulse could scarcely be felt, and the mucous membranes were 
discoloured and covered by petechial spots. In fact, the symp- 
toms of prostration of strength were too evident, and foretold 
that the close of the case was at hand. The horse died on the 
5th of August, the twelfth day after the first appearance of the 
disease. 
The abdominal cavity contained more than twenty pints of a 
yellow fluid, plainly exhaling the smell of urine. A great number 
of fibrino-albuminous flocculi were floating in this liquid. Traces 
of recent inflammation were observed on all the principal abdo- 
minal viscera, particularly on the liver, the stomach, and the 
small intestines, the surfaces of which were partly covered with 
false membranes slightly adherent. The sub-peritoneal tissue 
corresponding to these false membranes was injected. The 
intestines contained a great quantity of a black fluid, of an 
infectious odour, and which seemed to be partly formed of 
decomposed blood. 
The bladder, almost empty, lay, in a great measure, on the 
symphysis pubis, and presented at its inferior part, and near its 
neck, an opening through the membranes, round, larger exte- 
riorly than at its base, and of an infundibulous shape. 
An osseous tumour, situated on the superior face of the sym- 
physis pubis, near its anterior border, was lodged in this opening, 
consequently penetrating into the interior of the bladder, and 
fixing it in the situation in which it was found. This tumour, 
which was about an inch and a quarter in height, was rounded 
at its base and terminated by a dull point a little irregular in its 
form. There also existed, on the left side of the neck of the
