348 DISEASES OF THE HORSE’S FOOT 
Probably the best solution for use in this way is the old- 
fashioned Villate’s solution (see p. 199). 
This liquid should be injected at least every day, and, in 
a bad case, even two or three times daily. Practical hints 
to be borne in mind when attempting to cure quittor by 
means of injections are these: 
If the fistulas are numerous, the fluid should be injected 
into their various orifices. 
In order to force the fluid to the bottom of each diseased 
track, it is necessary, when injecting one opening, to firmly 
close ali others. 
Several injections should be made at each time of in- 
jection. In other words, we must not be content with just 
forcing fluid in. It must be forced in, and again forced 
out by a further syringeful. The fistulous tracks must, in 
fact, be washed in the liquid. 
The effect of the injection during the first eight or ten 
days is to render suppuration more abundant and whiter. 
After two weeks of the treatment sloughing of the inside of 
the sinuses occurs, and healing of the wound commences. 
Signs that this is occurring are—slight hemorrhage at the 
end of each injection, and a gradually increasing difficulty 
in forcing in the fluid. 
The Making of Counter-openings to the Fistulas.—Although 
Villate’s solution or any other caustic used in the manner 
we have described often effects a cure, many practitioners 
insist on the fact that a counter-opening to the fistula must 
also be made. 
The probe is used and the direction and depth of the 
fistula ascertained. Through the wall is then made an 
opening at exactly opposite the lowest point found by the 
probe, or through the sole if the probe should there lead us. 
This opening is best made with a sharp-pointed iron, and 
may afterwards be kept large enough by an occasional 
trimming with the knife. Many of the older authors, and 
with them writers of the present day, declare that unless this 
is done the ordinary injection is likely to fail in a great many 
instances where it would otherwise have been successful.
