the inner surface
of the ribs, as it would otherwise be impossible for him to give the
pleura its healthy, smooth aspect, from the firm manner in which the
abundant false membranes adhere to it. The diseased lungs sometimes
attain inordinate weight. They have been known to weigh as much as sixty
pounds.

_Treatment._--The veterinary profession is regarded by many who have
sustained heavy losses from pleuro-pneumonia, as deeply ignorant,
because its members cannot often cure the disease. Persons forget that
there are several epidemics which prove equally difficult to manage on
the part of the physician, such as cholera, yellow fever, etc. The
poison in these contagious, epizooetic diseases is so virulent that the
animals may be regarded as dead from the moment they are attacked. Its
elimination from the system is impossible, and medicine cannot support
an animal through its tardy, exhausting, and destructive process of
clearing the system of so potent a virus. All antiphlogistic means have
failed, such as blood-letting and the free use of evacuants.
Derivatives, in the form of mustard-poultices, or more active blisters,
are attended with good results. Stimulants have proved of the greatest
service; and the late Prof. Tessona, of Turin, strongly recommended,
from the very onset of the disease, the administration of strong doses
of quinine. Maffei, of Ferrara, states that he has obtained great
benefit from the employment of ferruginous tonics and manganese in the
very acute stage of the malady, supported by alcoholic stimulants.
Recently, the advantages resulting from the use of sulphate of iron,
both as a preventive and curative, have been exhibited in France. It
would appear that the most valuable depurative method of treatment yet
resorted to is by the careful use of the Roman bath. Acting, like all
other sudorifics in cases of fever and blood diseases, it carries off by
the skin much of the poison, without unduly lowering the vital powers.

_Prevention._--The rules laid down in Denmark, and indeed in many other
places, appear the most natural for the prevention of the disease. If
they could be carried out, the disease must necessarily be stopped; but
there are practical and insuperable difficulties in the way of enforcing
them. Thus, a Dr. Warneke says, prevention consists in "the avoidance of
contagion; the slaughter of infected beasts; the prohibition of keeping
cattle by those whose cattle have been slaughtered, fo
