of his own accord, and on the nineteenth day he was sent back to 
his master. 
Three cases of fracture of the jaw have come under our care in 
the course of this year. The first occurred to an ass, four years 
old, that was attached, by the reins of a bridoon, behind a carriage 
drawn by two horses. This poor animal, falling as it was going down 
hill, was dragged for a little distance before its misfortune was dis- 
covered, and the bit of the bridoon fractured the anterior maxillary 
bones. When he was brought to us, the muzzle was turned up, 
and easily moveable ; the superior dental arch was separated from 
the lower one about the space of an inch, and extended beyond it 
almost as much. A transverse wound existed in the superior in- 
terdental space, at a little distance from the two corner incisive 
teeth. The arch of the palate also presented a wound, an inch 
wide, through almost its whole length. When we moved the an- 
terior fragment of the bone, we were assured that the fracture ex- 
tended beyond the tushes in the direction of the anterior maxil- 
laries, which, to all appearance, had been violently forced from 
their natural situation. 
We replaced, as well as we could, the end of the jaw in its 
normal position, and retained it there by means of a leathern band- 
age. This bandage, which had the form of the bar of a bridle, had 
a large nose-band, which could be tightened or slackened by straps 
and buckles. An opening was left opposite to the interdental 
spaces, to permit the injection of liquid food into the mouth. To 
two metal rings, corresponding in height with the commissure of the 
lips, there was fitted, on either side, a twisted plate of iron wire, 
enveloped in a leathern sheath, which, in passing under the lip, 
surrounded the superior alveolar border, so as to fix it and gradu- 
ally bring it behind and below the corresponding portion of the 
fractured jaw. 
The wounds in the soft portion of the palate were cicatrized on 
the twentieth day, and on the twenty-fifth day a callus was formed 
sufficiently to enable us to permit the patient to eat some hay. 
The second subject was a young ass, eight or nine months old. 
The fracture was of the right branch of the inferior maxillary bone, 
a little behind its union with the left branch. The fracture was 
caused by a kick from a horse. The tumefaction of the soft parts 
was very great, and the first molar tooth was so much loosened 
as to render it necessary to extract it We retained the fractured 
portions in their natural position, without displacing the anterior 
one, by means of a simple linen bandage in the form of a nose 
band, which served, at the same time, for the application of a de- 
fensive cataplasm, which the contused state of thfe external soft 
parts rendered necessary. The patient was nourished, during the
