unced and the cause of the disturbance is to be sought,
particularly if the condition be due to a nail puncture.

[Illustration: Fig. 62--Elephantiasis.]

Treatment.--Location of the site of injury is advisable in all cases
and in some instances provision for drainage, as in puncture wounds, is
helpful. Locally, curettage and the application of suitable antiseptics
are indicated. Hot fomentations are beneficial and should be continued
for several days if necessary, to stimulate resolution. A brisk purge
should be admintered at the onset and strychnin, because of its indirect
stimulative effect upon the circulation together with its tonic effect
upon the musculature, is beneficial.

In all such cases rational treatment, good hygiene and careful nursing
are the principal factors which stimulate recovery. Individual
resistance or lowered vitality has a marked influence on the course of
this affection.

NON-INFECTIOUS LYMPHANGITIS.

This type of lymphangitis is associated with, or the result of, a
derangement of digestion. It affects heavy draft horses, rarely other
types of animals, and involves one or both hind legs.

Occurrence.--In healthy and well nourished horses irregularly used,
this affection may suddenly manifest itself. It occurs in singular
instances in mares that are in advanced pregnancy even when such animals
are at pasture. Usually, however, this malady is found in heavy draft
horses that have been kept stabled from one to three days.

Symptomatology.--At the outset in severe cases, there is elevation of
temperature, labored breathing, accelerated pulse, anorexia and more or
less swelling of the affected members. Swelling is very painful and when
the affected legs are palpated, pain is manifested by flinching. The
inguinal lymph glands are often swollen but in some cases they are not
affected in any perceptible degree. In the average case suppuration does
not occur and when conditions are favorable, resolution is complete
within ten days. The extent of the involvement and the intensity of the
affection vary materially in different cases and a chronic lymphangitis
may succeed the acute attacks and finally in some instances,
elephantiasis results.

Treatment.--An active purgative should be given at once and in the
ordinary case, stimulants are indicated. If marked distress is present,
morphin is given and where there is much rise of temperature, cold
drinking water is offered in abundance and cathar
