ON THE RE-ABSORPTION OF PUS.

similar to that from the wound escaped from them. Such were 
the chief exterior lesions which appeared until the 26th, when 
the horse died. 
It may be proper to remark, that from the appearance of farcy 
to the death of the animal the pulsations of the heart were unusu- 
ally powerful. 
Examination, six hours after death.—Of the lesions which 
bore more especially on the fact of the absorption of pus, tha 
following were the chief:— the lymphatic vessels emanating from 
the wound of the tendon, as well as those that were in the neigh¬ 
bourhood of the softened buttons, were surrounded with infil¬ 
trated cellular texture, filed with white matter of a caseous con¬ 
sistence, and having the character of pus. 
It is true that the veins coming I’rom the diseased limb did not 
contain pus; but the blood which they contained was firmly co¬ 
agulated and divided into two clots, perfectly distinct and separate 
from each other; the one white, firm, dijficult to crush, and re¬ 
fecting a light green shade; the other black and solid, but of 
much less consistence. 
The heart presented some ecchymoses on its surface, particu¬ 
larly around the coronary vessels. The right cavities were occu¬ 
pied by an enormous clot, hard, torn by strong pressure, and suf¬ 
fering a citron-coloured serosity to escape. This clot, exactly 
moulded to the internal surface of the ventricle and the auricle, 
prolonged itself into the anterior and posterior venae cavae. In 
the latter vessels only it was united with a small black clot. 
The left cavities contained only a small coagulum, black and 
white. No alteration was observed on the interior serous mem¬ 
brane of the heart. 
The spleen, much enlarged, was soft; the blood which it con¬ 
tained was black, thick, patchy, and readily escaped on slight 
pressure when an incision was made into this viscus. 
Many small ecchymoses were perceived here and there in the 
substance of the left lobe. There were found, besides, more than 
twenty little masses of concrete pus, easily crushed by the fingers, 
and surrounded, some of them, by pulmonary tissue slightly ec- 
chymosed, and others by tissue perf ectly sound: none icere encysted. 
In the right lung these masses were more numerous, and 
nearer together. In the centre of some was pus already softened. 
The cellular interlobular tissue, which surrounded these masses, 
was infiltred by a great quantity of citron-coloured serosity, 
which established between them and the farcy buttons a very 
striking analogy. The pus that constituted these masses be¬ 
ing collected and compared with that drawn from the farcy-but¬ 
tons, and from the lymphatics, was most like the latter.
