overfilling and bursting of the vessels give cause thereto. Slight 
hemorrhages can pass over without leaving any trace, but greater 
ones can cause important disturbances. By the rupture of 
greater vessels death can occur instantly, not from a lack of blood, 
but by overfilling of the pericardium and preventing the heart’s 
functions. 
(E) Inflammation of the Fleshy Substance of the Heart. 
Myocarditis .—An inflammation of the fleshy substance of the 
heart is generated by traumatic influences, foreign bodies, and 
the like. That part of the foreign body which penetrated the 
muscle of the heart and is not hidden in the fleshy substance, is 
as a general thing encased within a solid fibroid capsule. The 
point surrounded by fibrine projects entirely into the cavity of 
the heart; on the rugged edges, bloody, dark, fibrinous coagula¬ 
tions, sinewy solid white callosities are found, which in part pene¬ 
trate the pericardium in form of ramified fibrous masses and 
partly take the place of the fleshy substance of the heart in 
various expansions. They occur mostly in the left ventricle 
toward the apex, and if they be extended, give cause to aneurism 
of the heart. 
The muscular fibres are found in the different stages of soft¬ 
ening and fatty degeneration. Small abscesses in portions of the 
softened and relaxed muscle of the heart are not rare, as also in 
pysemic animals abscesses are found in the fleshy substance of 
the heart. The condition described here is also the same in 
myocarditis not of traumatic origin, and is congruent with this. 
(F) Inflammation of the Inner Lining of the Heart. 
Endocarditis .—The anatomical changes and conditions show 
the following features: 
Seldom diagnosticated during life, endocarditis in horses is 
occasionally found as a complication with other diseases, such as 
inflammation of the lungs, pleurisy, peritonitis and acute consti - 
tutional ailments, also after large doses of digitalis. It attacks 
different portions of the interior lining of the heart; now the lin¬ 
ing of the cavity partially; now the valves of the heart, or both 
simultaneously. However, the seat of the endocarditis is not
