rane of the
mouth and pharynx is covered with mucus, is reddened in spots, and shows
superficial, yellowish-gray, cheesy patches, which represent dead tissue,
and when removed expose ulcerated depressions. The same reddening in spots
and the yellowish-gray, cheesy deposits or patches are found in the fourth
stomach, the small intestines, and more rarely in the cecum, while the
third stomach, or manyplies, is more or less impacted with dry, hard feed.
Similar changes may be found on the mucous membrane of the nasal cavity,
larynx, trachea, the uterus, vagina, and rectum. The lungs may be injected,
edematous, or pneumonic. The heart muscle is pale and flabby, and
frequently hemorrhages are observed in its internal membrane. The liver may
be pale or injected with blood, and at times shows hemorrhages beneath its
capsule. The bile is thin and watery in consistence. The kidneys may be
inflamed or contain small hemorrhages within their substance or under the
capsule. The lymphatic glands may be swollen and injected or even
hemorrhagic.

_Treatment._--On account of the danger of spreading the infection, neither
medicinal treatment nor inoculation is permitted in European countries,
with the exception of Russia, where the disease is more generally diffused.
The most effective method of exterminating rinderpest in those districts in
which the disease is not indigenous has been found to be the slaughter of
all affected and exposed animals. Where the disease is general, successful
efforts adopted for its control have followed the immunization by
inoculation of the exposed animals and a strict application of appropriate
sanitary measures. This protective inoculation has been practiced with very
gratifying results in Russia, South Africa, and in the Philippine Islands.
An active immunity is thus induced in susceptible animals which lasts until
the danger from exposure to the disease is over. This immunity may be
attained (1) by the inoculation of pure bile from an animal which recently
died of rinderpest, (2) by the inoculation of glycerinated bile, followed
by pure bile or virulent blood, or (3) by the simultaneous inoculation of
strong standardized serum and virulent blood.

The latter method has been adopted by the United States Government in its
endeavor to exterminate the disease in the Philippines, and to protect the
cattle and carabaos against rinderpest after their importation into those
islands. Owing to the existence of th
