arkedly lame on the off hind-foot, knuckling
at the fetlock, and taking a long stride with the injured limb. There was
a punctured wound at the toe. The horn was pared, and antiseptic poultices
applied. Notwithstanding the antiseptic treatment pus continued to form. At
the end of a week sufficient horn was removed to ascertain the cause of
the constant suppuration. A movable object was found at the bottom of the
wound, and a piece of bone as large as a sixpence finally removed. Recovery
was uneventful.'

2. 'A filly was attended for a discharging fistula at the coronet.
Externally it had all the appearances of a quittor. At first no history
was given. The filly went scarcely lame at all, and had never been shod.
Treatment with poultices and caustic injections was useless. Finally the
filly was cast and the foot examined. A piece of bone, apparently part of
the wing of the os pedis, was removed, and the case made a good recovery.
Subsequent inquiries elicited the fact that the animal had kicked at and
hit a gate-post, and it was judged that then the injury had occurred.'

3. 'The subject was a bay horse, nine years old, used for railway shunting.
On August 7 he was found to be intensely lame of the near hind-limb, and,
after inquiries, there was no evidence bearing on the cause, as is often
the case, and at times this comes to light when least expected.

'I was called in consultation on September 2, and found him suffering
acute pain, with great swelling around the coronet. The foot was examined
thoroughly, and the diagnosis was fracture of the pedal bone, and immediate
slaughter was recommended. However, that was not carried out, and he died
on September 22.

'The post-mortem inspection revealed a complete fracture of nearly the
whole of the articulating surface and the left wing of the pedal bone (as
shown in Fig. 160).'[A]

4. A further interesting case is reported by Mr. William Hurrell.[A] Here
the cause was presumably galloping in the field, for the subject, a cart
mare running out at grass with her foal, was suddenly found to be lame.

[Footnote A: _Ibid_., vol. v., p. 408.]

As the lameness continued to increase in severity, Mr. Hurrell was called
in on August 1, and diagnosed the case as one of foot lameness. On this
date the foot was pared out, and a large accumulation of pus
