DISEASES OF THE HEART IN DOMESTIC ANIMALS.

Had the Association considered the questions and given expression to their 
conclusions, then the hands of the few veterinarians engaged in official work 
would have strengthened, and the public enlightened as to the exact status of the 
different plagues which afflict our domestic animals; while the mercenary indi¬ 
viduals and corrupt legislation would have received a check in their endeavors to 
make political capital or create places for partisans, at the expense of a suffering 
public and in defiance of all laws of sanitary science.

III. Anatomical Disturbances—Pathological Anatomy. 
It is a well known fact, that at a post-mortem examination many- 
sided anatomical disturbances and pathological changes of the 
heart and pericardium are found, where during life, heart dis¬ 
eases had scarcely been suspected. The post-mortem examina- 
nation reveals that the change found in the heart had been the 
most important factor in the calling forth of the fatal disease. 
In the following we shall discuss all such pathological ana¬ 
tomical changes as they are found upon the cadaver, be these 
diagnosticated during life or be they known for the first time at 
the post-mortem examination. 
In the first place, it is important that we divide the collective 
changes of the heart into two categories, namely : The innate and 
the acquired abnormities. We cannot always determine posi¬ 
tively whether the existing changes be innate or acquired, for in 
the innate abnormities, however slight, the germ for the develop¬ 
ment of this mortal affection slumbers; still I hold this division 
necessary for better understanding. 
(A) Innate Defects of the Heart .—The innate defects of the 
heart are not as rare as is generally believed; however their 
diagnosis, even on the cadaver, is uncommonly difficult, for as a 
rule, it is found that a number of pathological processes and
