The vessels of the mesentery are filled with muddy blood, and we may
find more or less extensive hœmorrhages into it. The fat around the
kidneys is often charged with yellow gelatiniform serosity which may
be deep coloured.

The, intestines are frequently changed in a very marked manner, the
changes being those of congestion, ecchymoses, and hæmorrhages. The
contents of the intestine may be charged with blood of a dirty-black
colour. Sometimes we may observe a truly apoplectic condition of the
intestinal mucous membrane with a layer of escaped; blood at its surface
and in its thickness; the tissue of the mucous membrane is then infil-
trated with blood or with a sero-sanguinolent fluid.

The liver is earthy, yellow, very friable, and it has the appearance
of having been cooked or macerated; its vessels are gorged with black
muddy blood, and we may see patches of hæmorrhage on its surface.
The bacilli are numerous in the vessels.

The spleen is generally hypertrophied, more particularly in the small
ruminants; sometimes, however, it is almost normal, neither tumified,
swollen, softened, nor black, and this is more particularly the case when
death has come on rapidly, time not having been allowed for the whole
organism to become invaded completely. Although we are not warrant-
ed in rejecting the idea that Anthrax cannot be present when we find the
spleen normal, still at the same time it is none the less true that in many
cases the examination of this organ is of great importance in diagnosis.
In fact, very frequently the spleen is found to be hypertrophied, tumified,
softened, and of a black or dark brown colour. It is sometimes enormous-
ly congested and swollen and presenting a very large increase in volume.
Sometimes the congestion takes place at certain spots from which results
a lumpy appearance of soft tumors, which on incision let escape a
black muddy fluid. The bacilli are found in the spleen in enormous
quantities.

The kidneys are generally congested ; the cortical layer more or less
deep coloured, and we find ecchymoses, hæmorrhages, and numerous
bacilli. The vesical mucous membrane is congested. The urine becomes
brown, sanguinolent, and contains bacilli. This latter condition is more
especially met with in the sheep, and is explained by vascular ruptures
in the kidneys and the passage of the blood into the urine.

The lungs are more or less congested in parts and present ecchymoses,
hæmorrhages, and blood-clots.

The pleura also are congested.

Respiratory mucous membrane is congested, ecchymosed, and covered
with a sero-mucous sanguinolent material. Lastly, the lesions of char-
bon may be found in the nervous centres. The arachnoid is sometimes
