HEPATIRRHCEA. 
The substance of the liver was not torn, and it was of a pale 
yellow colour, its granulations not very distinct; yet it had little 
consistence, and seemed to disappear bv the simple act of wash¬ 
ing. In other lacerations of the liver its substance remains the 
same, and no clot of coagulated blood is found. 
The middle lobe presented similar lesions, with the exception 
that the clot of blood spread itself under the peritoneum, and 
had not ruptured that membrane. There was neither rupture 
nor haemorrhage in the left lobe, but which presented the same 
altered tissue. On the middle of its anterior face was an ovoid 
cyst, six inches long and three wide, with its walls thick and 
fibrous. The internal coat of the cyst was covered by a dark 
red, fibrous substance, having the appearance of muscle. The 
spleen was softened, and its tissue lacerated by the slightest 
pressure. 
Another horse, after being driven rapidly for twelve leagues, 
heaved sadly at the flanks, and the breathing was accompanied 
by a peculiar rattling. On the following day the animal passed 
with difficulty urine highly reddened with blood. Injections 
were administered, and it was brought to the school at iVlfort. 
The conjunctival, nasal, and buccal membranes were pale, and 
somewhat livid ; the base of the ears and the extremities, and, in¬ 
deed, the whole of the frame, were cold ; the animal was in one 
continual and violent trembling, so that it was impossible to as¬ 
certain the state of the pulse. The horse staggered and fell; 
arose after a few minutes ; once more fell, and died in a few 
seconds. The middle lobe of the liver was torn, the right was 
gorged with blood, and the left in its natural state. The portion 
\vhich was torn was yellow, softened, and divided into little 
masses : there seemed to be black blood effused through the 
whole organization of the liver. Much black blood was found in 
the abdomen. M. Dupuy imagined that, in the rapid travelling 
of the horse, a great quantity of blood had penetrated into the 
tissue of the liver, and had lacerated the parenchymatous sub¬ 
stance of that organ; that in the fall of the animal the capsule 
was torn, and that the effusion into the abdomen only preceded 
the death of the animal a few minutes. 
A third horse staggered and fell in consequence of a severe and 
sudden lash of the whip. He struggled a few moments, and died. 
A portion, not only of the capsule, but of the substance of the 
middle lobe of the liver, was torn three inches long, and one inch 
in depth. About eight pounds of blood were effused in the cavity 
of the abdomen. 
The Errata referred to by Mr. Ralston shall be noticed at the end of the volume.
