FATTY DEGENERATION OF THE HEART.

Fatty degeneration may involve the whole organ, or may be limited to its
walls, or even to circumscribed patches. The latter is situated at the
exterior, and gives it a mottled appearance. When generally involved it
is flabby or flaccid, and in extreme cases collapses when emptied or
cut. Upon dissection the interior of the ventricles is observed to be
covered with buff-colored spots of a singular zigzag form. This
appearance may be noticed beneath the pericardium, and pervading the
whole thickness of the ventricular walls, and in extreme cases those of
the fleshy columns in the interior of the heart. These spots are found
to be degenerated muscular fibers and colonies of oil globules. Fatty
degeneration is often associated with other morbid conditions of the
heart, such as obesity, dilatation, rupture, aneurism, etc. It may be
connected with fatty diseases of other organs, such as the liver,
kidneys, etc. When it exists alone its presence is seldom suspected
previous to death. It may be secondary to hypertrophy of the heart, to
myocarditis, or to pericarditis. It may be due to deteriorated
conditions of the blood in wasting diseases, excessive hemorrhages,
etc., or to poisoning with arsenic and phosphorus.

_Symptoms._--The most prominent symptoms of fatty degeneration are a
feeble action of the heart, a remarkably slow pulse, general debility,
and attacks of vertigo. It may exist for a long time, but is apt to
terminate suddenly in death upon the occurrence of other diseases,
surgical operations, etc. It may involve a liability to sudden death
from rupture of the ventricular walls.

_Treatment._--Confinement in feed to oats, wheat or rye bran, and
timothy hay. Twenty drops of sulphuric acid may be given in drinking
water three times a day, and hypophosphite of iron in 2-dram doses,
mixed with the feed, twice a day. Other tonics and stimulants as they
may be indicated.

RUPTURE OF THE HEART.

This may occur as the result of some previous disease, such as fatty
degeneration, dilatation with weakness of the muscular walls, etc. It
may be caused by external violence, a crushing fall, pressure of some
great weight, etc. Usually death follows a rupture very quickly, though
an animal may live for some time when the rent is not very large.

WEAKNESS OF THE HEART.

This may arise from general debility, the result of exhausting disease,
overwork
