DISEASES OF THE HEART. 
401 
pitation increased, cardiac beat over a large portion of the chest, 
lifting the hand at each beat on percussion ; an increased area of 
dullness forward, backward and downward ; on auscultation a 
distinct blowing murmur was heard taking the place of the first 
sound of the heart, and an increase in the intensity of the second 
sound. There was no dropsical condition of the extremities or 
other portion of the body. 
A diagnosis was made of eccentric hypertrophy of the heart, 
with tricuspid regurgitation, with prognosis unfavorable. 
It was suggested to have the horse sent to the American Vet¬ 
erinary College for the benefit of the surgeons and students, as 
being an exceedingly rare and interesting case, and to have a 
post mortem examination made, as the death of the animal was 
expected soon. Through some neglect, nothing was heard of 
him until Tuesday evening, when a postal card was received stat¬ 
ing that the horse would be sent down Wednesday; but instead 
of the horse, the heart and a portion of the lungs were sent, he 
having died during the night in a delirious condition. 
Post mortem .—Heart and lungs : Heart enormously enlarged, 
especially in the horizontal diameter; muscular wall indurated 
and stiff; weight, eleven and a half pounds; ventricular mass, 
eight pounds ; auricular mass, three and a half pounds ; left ven¬ 
tricular cavity about normal size, walls hypertrophied from 
one and a half to two inches in thickness; right ventricle dilated 
and hypertrophy of wall one inch and a half in thickness ; left 
auricle dilated and wall hypertrophied ; right auricular cavity 
enormously dilated and walls thickened ; both auricular walls 
three-quarters of an inch to one inch in thickness; mitral valves 
indurated, opaque, and portion adhering to walls; chordoe 
tendinse retracted ; tricuspid valve thickened, three or four 
nodules on under surface, and chordoe tendinas retracted; 
semilunar valves normal. On water test, the valves were so in¬ 
sufficient as to admit of a large-sized finger. Lungs—Portion 
hypostatic and bronchia filled with frothy mucus. 
It is to be regretted that an examination of the abdominal 
organs was not made. 
Case No. 2. —An eminent physician of this city has been 
driving a bay gelding, nine years of age, on his daily visits for a
