MANUAL OF MODERN FARRIERY. 
As in all other inflammatory diseases, there is heat in the 
seat of the navicular bone, and probably in the whole foot. 
In this complaint the animal suffers much pain, to alleviate 
which we would recommend neurotomy , or cutting out a 
portion of the nerve, which has in some instances very 
much reduced the lameness. But at all events it will lessen 
the sufferings of the horse. In cases of extreme lameness, 
either with or without contraction, then it would be inju¬ 
dicious to resort to this operation; because, if there was 
ulceration of the membrane or decay of the bone, the 
increased friction, in consequence of the freer action given 
to the parts, the feeling of pain being removed, would 
cause these to progress more rapidly, until complete dis¬ 
organization of the foot took place; or in all probability 
the tendon itself would be gradually worn through by 
nibbing against the roughened surface of the decayed bone. 
FALSE QUARTER. 
When the coronary ligament is severely cut or divided, 
it is termed false quarter. In some instances it is eaten 
through by the application of caustic applied to other 
wounds and sores of the foot; when this is the case there 
will be a division of the horn as it grows down, having 
all the appearance of a sand-crack, or one portion of the 
horny substance will overlap the other. This is a very bad 
defect in the foot, and often occasions lameness, and there 
is very great difficulty in curing it. The coronary ligament 
is that by which the horn of the hoof is secreted; con¬ 
sequently what must be first attempted is to restore it 
to the discharge of its healthy function. 
Remedies. —Caustic has been used in many instances, 
and found effectual; but nevertheless it is a dangerous 
remedy, as it has often proved very injurious. Blisters
