A CASE OF ENDOCARDITIS, &c. 231 
pericardium, I applied two large vesicatories on the side of the 
chest. 
The blood coagulated in six or seven minutes, and presented 
scarcely any albuminous separation. 
2 5th . — All the symptoms have increased in intensity. The 
beatings of the flanks resemble those of a horse with violent cough. 
The pulsations of the heart are violent and precipitate, but the 
pulse at the jaw is less violent. The prostration of strength is 
extreme. 
In the night between the 25th and 26th the horse was con- 
tinually groaning, acute cries occasionally intermingling. This 
continued during a part of the 26th, when the difficulty of breath- 
ing approached almost to suffocation, and at six o’clock at night 
the horse died in violent struggles. 
Post-mortem examination at eight o’clock in the morning. 
The Thoracic Cavity . — The lungs were discoloured. Their 
volume was considerable, and had not diminished under the pres- 
sure of the air. They crepitated when pressed with the hand. The 
interlobular cellular tissue was infiltrated with air — there was 
general emphysema produced by the efforts attending the diffi- 
cult breathing. The pericardium presented nothing' remarkable. 
The heart was more voluminous than usual. The right ven- 
tricle was distended and flaccid. The cavity of the ventricle pre- 
sented everywhere, 1st. A minute injection of the lining mem- 
brane of the heart, particularly at the base of the valves. This 
injection was also observable in the corresponding auricle. 2d. 
Small but numerous ecchymoses in the cellular tissue beneath 
the internal membrane of the right cavities. These ecchymoses 
were very red, but did not extend into the muscular tissue. 3d. 
A large cylindrical clot, very hard, and of a yellowish red colour, 
prolonged itself even to the pulmonary artery and its larger divi- 
sions, without any adherence to the parietes of the vessels. 
This clot perfectly resembled a tree with its trunk and 
branches. At its base it strongly adhered to that of the septum 
ventriculorum. There suddenly commenced a certain organ- 
ization. It was white, homogeneous, and as strongly adherent to 
the septum as if there were a kind of fusion between the tissue 
of the clot and the fleshy fibres of the septum. There the internal 
membrane seemed to have disappeared over a space as large as a 
crown, and, at the termination of its adherence to the clot,itseemed 
to have been considerably increased in thickness. It was opaque 
and white. A little farther on, the serous cellular tissue beneath 
was the seat of an intense injection. The muscular fibres at the 
point of their fusion with the clot had undergone a kind of trans-
