body or flesh, or other tissues are deeply stained, lienee the dark 
patches seen. The spleen is almost invariably altered; there is 
also the exudation of yellow gelatinous matter in various parts— 
particularly noticeable in horse-sickness. Lastly, there is the 
piesence in the blood and other fluids of u bacteria,” the specific 
germs of this disease in whatever form it may manifest itself. 
Anthrax Fever .—There is the usual distension of the body 
with gas and escape of bloody fluid from the external openings ; 
the flesh is dark in color, and when cut into black fluid blood is¬ 
sues. The external appearance of the stomach and intestines 
vaiies considerably. In some instances there are no special altera¬ 
tions, in others they are dark in color; but I have often seen 
them spotted all over, as though sprinkled with large drops of 
blood ; in some cases yellow gelatinous matter is effused all along 
the course of the intestines. 
It is on their internal surface, however, that the most constant 
symptoms appear, as the mucous membrane is invariably found 
of a deep-red color, as if intensely congested—in fact, during life, 
owing to the relaxed condition of the anus, it is not uncommon to 
see the membrane of a deep claret color—it seemed thickened, 
and the surface is covered with a jelly-like mucous. The spleen 
is usually of a livid color, but varies a good deal in size and ap¬ 
pearance, as does the liver; the kidneys, too, are dark in color. 
The lungs are often found congested, and frequently the ap¬ 
pearances are so much like horse-sickness that it is difficult to tell 
the one form from the other. The heart is invariably flabby, and 
the internal surfaces covered with dark patches. 
It will thus be seen that the blood is materially altered, both 
chemically and physically, there being a diminution of fibrine, 
which prevents its clotting, while the cells become disintegrated 
and lose their contents, giving rise to the brown color of the 
serum, which in its turn passes readily through the membranes 
and stains them. 
Ilorse-sickness .—Soon after death the body becomes distended 
with gas, and frothy mucous escapes from the nostrils ; on cutting 
into the abdomen the intestines are found discolored, and often¬ 
times the mesenteric glands also; the spleen, too, is dark in color
