there occurs a hyperplasia of the skin and subcutaneous
tissues, resulting in some instances, in the affected member attaining
an enormous size. Sporadic cases of this kind are to be seen
occasionally, and are apparently caused by repeated attacks of
lymphangitis. The affection is not benefited by treatment, and while a
horse's leg may become so heavy and cumbersome as to mechanically impede
its gait, as well as to fatigue the subject when made to do service even
at a slow pace, elephantiasis causes no constitutional derangement. The
hind legs, in elephantiasis, are affected and a unilateral involvement
is more often seen than a bilateral one. The legs may be enlarged from
the extremity to the body, but ordinarily the affection does not extend
higher than the hock or the mid-tibial region.

A chronic, progressive, hyperplastic-degeneration exists in some cases
and the subjects are in time rendered unserviceable because of the
burden of getting about encumbered by the affected extremity. In other
animals hyperplasia progresses for a time--until the parts become
greatly enlarged and conditions apparently attain an immutable state.
Nevertheless animals so affected may continue in service for years
without being distressed.

AFFECTIONS OF THE FEET.

Lameness is very often due to affections of the feet, and in all foot
diseases probably the most constant cause is injury inflicted in some
manner. Resultant from injury, there frequently develops complications
and the one most often seen is infection.

Because of the fact that the feet are constantly exposed to germ-laden
soil and filth, if not actually bathed in such infectious materials, it
naturally follows that septic infection of some part of the feet must be
of frequent occurrence.

Subsequent to being obliged to stand in mud and other damp or wet media,
exposure to desiccating influences such as stabling upon dry floors, or
at service on hot and dry road surfaces causes the insensitive parts of
the feet to become dry, hard and brittle. This favors "checking" of the
protecting structures and it frequently results in the formation of
large fissures which expose the underlying sensitive parts of the feet
and lameness is the inevitable outcome.

The function of the feet--bearing the weight of the animal at all times
when the subject is not recumbent, and in addition to this, the
increased strain put upon them at heavy draft work, together with the
concussion and bu
