ing the bandages and dressings in position.

In this case a very useful shoe will be the three-quarter bar shoe. With a
little manipulation the bandages are easily run under the bar portion of
the shoe, and a few of their turns every now and again wrapped round the
bar in order to keep the whole firmly in position.

In connection with tendinous quittor, when septic matter has gained the
sheath of the flexor tendons, there is, for a long time after healing of
the fistula, a marked tendency for the animal to go on his toe. To a large
extent we judge this to be due to slight adhesions between the two tendons
brought about by the growth of inflammatory fibrous tissue. In such cases
benefit is sometimes derived from the application of a shoe with an
extended toe-piece (see Figs. 84 and 108).

C. OSSIFICATION OF THE LATERAL CARTILAGES, OR SIDE-BONES.

_Definition_.--An abnormal condition of the lateral cartilages, in which
the substance of the cartilage becomes gradually removed and bone formed in
its place.

[Illustration: FIG. 143.--OSSIFIED LATERAL CARTILAGES (SIDE-BONES).]

_Symptoms and Diagnosis_.--Side-bones are nearly always met with in heavy
draught animals, and are rarely seen in the feet of nags. They are,
moreover, nearly always confined to the fore-feet. In the ordinary way
little need be said concerning their characteristics, and the way in which
they may be detected. Neither need any concern be ordinarily manifested
with regard to the effect they may have on the animal's gait and future
usefulness. Seeing, however, that side-bone constitutes one of the
recognised hereditary diseases, and that at the various agricultural and
horse shows its existence or otherwise in a certain animal is a matter of
great importance, some little attention must be given to these two points.

With a side-bone anywhere approaching full development, diagnosis is easy.
The thumb is pressed into the coronet over the seat of the cartilage, when,
in place of the elasticity we should normally meet with, we have the solid
resistance offered by bone. In some instances diagnosis is even easier
still. We refer to those cases in which the side-bone stands above the
level of the coronet with such prominence as to be readily _seen_ and
recognised without manipulation, and where its growth has caused distinct
enlargement and bulging of the wall of the affected quarter. It seems that
in such cases the bone-forming process does not end with s
