suitable.

All this, of course, calls for keeping the animal in the stable. It is far
better, however, more especially if a piece of marshy land is at hand, to
turn him out in that. A moderate amount of exercise is beneficial rather
than not, and the feet are thus constantly kept damp without trouble to the
attendants.

The second indication in the treatment is that of applying a
counter-irritant as near to the diseased parts as possible. Regarding its
efficacy we must confess to being somewhat sceptical. The treatment has
been constantly practised and advised, however, and we feel bound to give
it mention here. A smart blister may, therefore, be applied to the whole of
the coronet, and need not be prevented from running into the hollow of the
heel.

Instead of blistering the coronet (or in conjunction with that treatment),
the counter-irritant may be applied by passing a seton through the plantar
cushion or fibro-fatty frog. Setoning the frog appears to have been
introduced by Sewell. In many cases great benefit is claimed to have been
derived from it, especially by English veterinarians of Sewell's time, and
by others on the Continent. Percival, however, was not an advocate for it,
and, at the present day, it is a practice which appears to have dropped out
of use altogether.

[Illustration: FIG. 164.--FROG SETON NEEDLE.]

To perform this operation a seton needle of a curved pattern is needed
(see Fig. 164). This is threaded with a piece of stout tape dressed with a
cantharides, hellebore, or other blistering ointment, and then passed in at
the hollow of the heel, emerging at the point of the frog. The course the
needle should take will be understood from a reference to Fig. 165.

The seton may be passed with the horse in the standing position. Previously
the point of the frog should be thinned, and the animal should be twitched.
After-treatment consists simply in moving the seton daily, and dressing it
occasionally with any stimulating ointment, or with turpentine.

If, in spite of these treatments, the disease persists, then nothing
remains but neurectomy.

D. DISLOCATIONS.

The firm and rigid manner in which the bones of the pedal articulation
are held together renders dislocation of this joint an exceedingly rare
occurrence, and then it is only liable to happen under the operation of
great force. In the literature to our hand we have only been successful
in discovering one reported instance, and, strang
