relief is
evident, and in the opposite position, the condition is aggravated.
This experiment may be used for diagnostic purposes.

Treatment.--When the anatomy of the diseased parts is taken into
consideration, and an analysis of the lesions which occur in cases where
considerable structural change is occasioned by this affection, it is
obvious that recovery is impossible. Only in cases where the
inflammation is promptly checked before damage has been done the
navicular bone or the flexor tendon, is permanent recovery possible. The
disease is not frequently treated during this stage, however, and in the
majority of instances the condition becomes chronic.

As soon as a diagnosis is made the shoes must be removed, the toe
shortened with the hoof pincers and rasp and the subject is put in a
well bedded box-stall. If the animal is very lame and the inflammation
is acute, ice-cold packs should be applied to the feet. As soon as acute
inflammation has subsided the foot may be so pared that all excess of
sole and frog is removed without lowering the heels, and the animal may
be blistered about the coronet region. The subject may be shod later,
with heel calks that raise the heel moderately and a protracted period
of rest should be enforced.

In cases where no acute inflammatory condition exists, neurectomy is
beneficial. One must discriminate, however, between favorable and
unfavorable subjects. This is not a last resort expedient to be employed
in cases where extensive lesions of the navicular structures exists.
With proper shoeing, and by putting the subject at suitable work, where
concussion of fast travel on hard roads is not necessary, the best
results are obtainable.

Laminitis.

This disease is primarily a non-infective inflammation of the sensitive
laminae which very frequently affects the front feet. Often all four
feet are affected, less frequently one foot (when its fellow is unable
to sustain weight) and rarely the hind feet alone.

Occurrence.--Probably a greater number of cases of laminitis occur in
localities where horses that are worked on heavy transfer wagons are,
when in a state of perspiration, allowed to stand exposed to sudden
lowering of temperature and to stand in a cool or cold shower of rain
such as occurs near the coast of the Great Lakes or the ocean in some
parts of this country.

This disease occurs in connection with digestive disorders of various
kinds and, because of the frequent
