and the fetlock; below this no sensation whatever, as a
pin was inserted in several places round the coronet without causing any
symptoms of pain. On further examination, two unnerving scars were found.
No treatment was adopted, and the horse was destroyed on January 6.

'On dissecting the leg, the following appearances presented themselves:

'The limb was very much enlarged, due to thickening of the connective
tissue, the skin being removed only with difficulty. The tendons were soft
and much thickened. A rupture of the skin at the coronet, just where the
skin meets the wall of the foot. Large extravasations of blood at the back
of the tendons, situated in the lower half. _External_ nerve trunk had
become reunited, at the point of junction there being a hard lump about
the size of a walnut. _Internal_ nerve trunk also had become reunited, and
presented a thickened portion at the point of junction, but not so large as
that of the outer side, and situated in the lower half of the tendon, about
2 inches higher than that on the external nerve. This nerve trunk was
atrophied below the thickening, and had undergone gelatinous degeneration.
Judging from the scars on the skin, this side had evidently been unnerved a
week or ten days previously to that on the outer side. The band stretching
across the back of the perforatus, between the external and internal
nerves, appeared on the inside to have become firmly fixed into the tendon.

'On removing the hoof, under the sole there appeared a large quantity of
very foetid pus; the laminae were very much inflamed in patches. There
was an enormous thickening of connective tissues in the heel. On cutting
longitudinally through the perforatus tendon, there was exposed a large
blood-coloured mass, of a gelatinous appearance, situated on the perforatus
tendon, the latter being very much thickened, and growing to the navicular
bone. The underneath surface of the superior suspensory ligament was much
thickened, and firmly adherent to the bone; at the posterior surface of
the metacarpus there was a quantity of gelatinous substance. The anterior
ligament of the fetlock-joint was thickened; the navicular bone was entire,
but showed lesions of navicular disease, being ulcerated. Section through
the bone did not reveal anything further. It may be here remarked that the
ulcerations were on either side of the central ridge, and not at all on the
ridge itself.
