eseen, but that it is for some time indiscoverable.
With the foot deprived of sensation, a nail may be picked up, or a prick
sustained at the forge, and no intimation given to the attendant until pus
has underrun the horn, and broken out at the coronet. What follows, then,
is that the hoof as a whole, or the greater part of it, sloughs off.

No neurectomy should be undertaken unless this contingency has been allowed
for. The owner should be advised of it by the surgeon, who should at the
same time enjoin on his client the absolute necessity of giving to the
neurectomized foot daily and careful attention.

_Loss of Tone in the Non-sensitive Area_.--In addition to the mischief
resulting from a wound going undetected, it must be remembered that the
loss of tone resulting from the operation gives to every wound (however
slight), in the region supplied by the removed nerve, a sluggish and
troublesome character. Difficult to deal with as wounds about the foot
ordinarily are, they are rendered more so by a previous neurectomy.

_Gelatinous Degeneration_. This is a condition liable to occur in cases
where the operation has been too long deferred, and when considerable
structural alteration has already taken place in the shape of diseased bone
or tendon, more especially in navicular disease. It consists in a peculiar
softening of the structures of the limb, accompanied with enlargement,
due to swelling of the connective tissues, the enlargement and softening
generally making itself first apparent by a soft, pulpy swelling in the
hollow of the heel.

From this onwards the enlargement increases, and lameness becomes
excessive, the animal going more and more on his heels, until, finally, no
portion of the solar surface of the foot comes to the ground at all.

The case is hopeless, and destruction should be advised.

_Reported Case_.--'The patient, a brown carriage gelding, was brought to
the Royal Veterinary College infirmary in a cart on December 31, the only
previous history obtainable being that it had suddenly fallen lame a month
before.

'The symptoms presented were excessive lameness of the near fore-limb. On
being trotted, the toe was elevated each time the foot reached the ground,
progression being entirely on the heels. Separation of the hoof for about 2
inches at the hinder part of the coronet; oedematous swelling from foot to
knee, extending during the next three days to the elbow. Great tenderness
between the knee
