SANGUINEOUS APOPLEXY.

are the principal seats of the external disorders I have described. 
Sometimes, all the parts composing these separate regions are con- 
founded together by the sanguineous infiltration. 
Thoracic Cavity . — If the sanguineous turgescence is manifested 
in the respiratory organs as well as in the exterior regions, the 
lungs are highly congested and augmented in volume ; their or- 
ganic tissue, already softened by blood, easily tears, and if touched 
with a sharp instrument, a greater or less quantity of black coagu- 
lated blood escapes. The bronchia and their ramifications are 
filled with a frothy bloody liquid. The bronchial ganglions, those 
at the entrance of the chest, are enormously gorged with blood, and 
contain a considerable quantity of colouring matter, which gives 
them a deep complexion. This immense tumefaction, with a deep 
red tint (which I have seen several times in the ox in similar cases) 
made met take the lymphatic ganglions for melanotic tumours at 
first; but subsequent observations shewed me my error. The pleurse 
themselves in general present no alterations ; but where the post- 
mortem examination has been delayed, a bloody serosity is fre- 
quently found in their cavities. In lambs, the thymus glands, and 
the loose cellular tissue which surrounds them, are gorged with 
black blood, giving them the appearance of an immense bloody 
clot. 
The abdominal Cavity . — When sanguineous congestion is mani- 
fest in the abdominal cavity, the principal parts of the organs are 
red and tumefied. The spleen is often double, nay, quintuple its 
natural size ; and it is soft or diffluent, gorged with black liquid 
blood, that cannot be got rid of by washing, but with great diffi- 
culty. The liver and the kidneys are likewise, in some cases, 
choaked with blood; but their tissue retains its firmness. The 
lymphatic ganglions of the mysentery, of the sub-lumbar region, 
are red, and often blackish. The loose and abundant cellular tissue 
which surrounds these parts is often also imbued and tinged with 
blood; black clots of this fluid are sometimes formed in the loins, 
and plastered on their surface. The hemorrhage also shews itself 
in the layers of the mysentery, and in the sub-mucous cellular tissue 
of the small intestines chiefly. Lastly, the blood may have per- 
vaded the mucous tissues of the same, and that of the pelvis of the 
kidney and the urinary bladder. The clot presents some arboriza- 
tions, and is even thickened in parts. The rumen, the maniplus, 
and the reticulum, are not visibly altered. 
The cranial Cavity and spinal Canal . — The sanguineous conges- 
tion frequently extends itself to the cephalic organs. Then the 
sinuses of the dura mater, the capillary vessels which traverse the 
external surface of the brain, and the spinal marrow are filled with 
black coagulated blood. The choroid plexus of the brain, and the
