                            DIABETES.

One form of diabetes is occasionally seen in the elephant,
characterized simply by profuse staling.

Causes.—In horses due to bad fodder and also to an undue
proportion of saline matters in the water. It may be inferred that
such causes may produce profuse staling in the elephant.

Symptoms.—Passage of large quantities of pale watery urine,
thirst, and gradually increasing loss of flesh.

Treatment.—Care with regard to food and water, and change
to another locality.

The following may be tried :—Iodide of iron in doses of 30 to 40
grains two or three times a day. Opium in doses of 2 drachms
twice or thrice daily.

Tonics, especially arsenic, iron and nux vomica, are indicated
(see Formulae 39 to 46).

                          LYMPHANGITIS.

A condition somewhat like this disease in the horse may
occasionally be met with in elephants So far I have only seen it
in yard elephants in Rangoon, and also in the elephant in the
Zoological gardens which has suffered from two or three attacks.
The attack usually occurs after a period of idleness. For no
apparent reason a limb, hind or fore, may be found in the morning
swollen, the animal being hardly able to place any weight on the
affected limb, which is painful, the animal often being lame. There
is possibly some fever, but the animals in which the condition was
observed were unsafe to handle. In horses the cause is due to some
irritation of the lymphatic glands, and the swelling due to materials
thrown out into the surrounding connective tissue as a result of the
inflamed condition of the lymph glands and vessels.

The condition may also arise from injuries such as wounds about
the feet and limbs due to some septic infection.
