IN HERBIVOROUS ANIMALS* 
235 
The treatment consecutive to the operation must principally 
consist in assiduous attention to cleanliness. On the first day the 
animal should be entirely deprived of all solid or fibrous food, 
which would require efforts of mastication. It is necessary to 
frequently gargle the mouth with acidulated fluid, which may 
be easily done by using the ordinary syringe. In fact, the animal 
should get nothing but a little thin gruel, and have his mouth 
washed after its use. Bleeding is often indicated, the quantity 
to be extracted being governed by the energy of the reaction 
consequent on the operation. The day after the operation the 
dressing must be raised. The interior of the sinus cauterized by 
nitric acid, or other caustic agent, will reflect a blackish tint. 
The vapour which it exhales disseminates a most repugnant 
odour, and there are generally some remains of putrid and altered 
alimentary matters mixed with the clots of blood enclosed in the 
cavity of the sinus. Detergents should be injected into the in- 
terior of this cavity, such as Lebarraque’s clorinated solution of 
soda, mixed with a gentian wine. The mouth should be cleaned 
with acid gargles ; and we should introduce a firm pledget of tow, 
chlorinated, into the space of the alveole, to oppose as much as pos- 
sible the passage of any thing from the mouth to the sinus. The 
regimen should consist of gruel only, and the gargles should be con- 
tinued often during the day. On the second, the borders of the 
opening of the sinus will be a little swollen. The work of reaction 
has commenced in the cauterized membrane ; the eschars detach 
themselves, and leave naked a rosy surface of a laudable aspect. 
The odour that escapes from the cavity is less repugnant. Con- 
tinue the same aromatic detergent injections, and the same food, 
with the addition of a little bran, and gargle often. But as the 
suppuration begins to establish itself, the dressings should be re- 
peated twice or three times during the twenty-four hours. 
It is not our intention to indicate the progress of the wound 
and the attentions it demands day after day. We would only re- 
mark in a general way that, according as the day on which the 
operation was performed becomes more distant, the tumefied bones 
and other structures proportionally lessen in the neighbourhood of 
the wound, and the membrane of the sinus takes on a uniform 
rosy tint, and a glistening humid aspect, proper to a mucous 
membrane; and, finally, the nasal flux ceases completely, the 
matter which may be secreted finding an exit into the mouth by 
the alveolar opening ; then the opening made by the trepan con- 
tracts itself by degrees, at the same time that the tables of the 
alveolar borders approach each other, and so tend to obliterate the 
cavity which formerly lodged the root of the diseased tooth. 
This work of repair ought to be aided by detergent dressings,
