tle displacement,
will unite rapidly, leaving a comparatively sound animal often quite
free from subsequent lameness. If there is much displacement, however,
only a ligamentous union will take place, with much deformity and more
or less irregularity in the gait. Other fractures may be followed by
complete disability of the patient, as, for example, when the cotyloid
cavity is involved, or when the reparatory process has left bony
deposits in the pelvic cavity at the seat of the union, which may, in
the case of the female, interfere with the steps of parturition, or
induce some local paralysis by pressure upon the nerves which govern the
muscles of the hind legs. This is a condition not infrequently observed
when the callus has been formed on the floor of the pelvis near the
obturator foramen, pressing upon the course or involving the obturator
nerve.

_Treatment._--In our estimation, the treatment of all fractures of the
hip bone should be of the simplest kind. Rendered comparatively
immovable by the thickness of the muscles by which the region is
enveloped, one essential indication suggests itself, and that is to
place the animal in a position which, so far as possible, will be fixed
and permanent. For the accomplishment of this purpose the best measure,
as we consider it, is to place the horse in a stall of just sufficient
width to admit him, and to apply a set of slings, snugly, but
comfortably. (See Plate XXXI.) This will fulfill the essential
conditions of recovery--rest and immobility. Blistering applications
would be injurious, though the adhesive mixture might prove in some
degree beneficial.

The minimum period allowable for solid union in a fractured hip is, in
our judgment, two months, and we have known cases in which that was too
short a time.

As we have said before, there may be cases in which the treatment for
fracture at the floor of the pelvis has been followed by symptoms of
partial paralysis, the animal, when lying down, being unable to regain
his feet, but moving freely when placed in an upright position. This
condition is owing to the interference of the callus with the functions
of the obturator nerve, which it presses upon or surrounds. By my
experience in similar cases I feel warranted in cautioning owners of
horses in this condition to exercise due patience, and to avoid a
premature sentence of condemnation against their invalid servants; they
are not all irrecoverably paralytic. With altern
