patch just above the ilio-cecal valve are considerably enlarged. 
Large intestines: Show a great many enlarged solitary glands, yet but little cenges 
tion. The rectum is much congested and presents two ulcers: one with raised edges 
and raw, depressed center; the other, with a firm, dirty-white slough in the center. 
Mesenteric lymphatic glands: Enlarged and thickly streaked with gray. Those near 
the ilio-cecal valve, and those above the rectum, are congested and deeply reddened. 
Inguinal glands: Are also greatly enlarged and streaked dark-gray with pigment. 
Liver: Of normal consistency and color, excepting some few patches of deep purple. 
Gall-bladder moderately filled with a yellowish-green, viscid bile. 
Pancreas: Healthy. 
Spleen: A portion very dark colored (nearly black) extending its whole length and 
about half its breadth; is evidently gorged with blood; but is not raised above the 
level of the remaining part. 
Kidneys: One contains an acephalocyst inits pelvis. The cortical substance of both 
is pallid, but no other change is noticeable.

Post-mortem examination.—Skin: Of ears, throat, breast, belly, and legs, of a uniform 
dark purple; white patches remain inside the forearm and thigh, and along the back, 
which is covered by avery thick scurf. The discoloration which is due to congestion 
of capillary vessels, the coagulation of blood within them, and numerous minute ex- 
travasations, is confined to the integument. The skin is also abundantly covered 
with the usual black concretions. 
Digestive organs: Tongue blue, but with no abrasions. ; 
Tonsils, fauces, and pharynx: The seat of general congestion and discoloration, 
(Esophagus has some spots of slight congestion. 
Stomach: Distended with solid food; not so strongly acid as in many other cases. 
Its great curvature has the mucous membrane covered with patches of blood extra 
vasation, such patches standing out in greater part as dark-red clots. 
Small intestine: Exceedingly contracted, almost empty, and congested throughout 
in varying degree, from a simple branching redness, with softening of the mucous 
membrane and excessive production of mucus, to distinct circumscribed extravasa- 
tions with decided thickening; in several instances the redness and the thickening 
is most marked on Peyer’s patches. The duodenum contains three ascarides. Several 
small ulcers exist just above the ilio-cecal valve. 
Large intestine: Cecum remarkably small and contracted. Neither caecum yor colon 
contains much ingesta. The mucous membrane along the whole large intestine is in- 
flamed, greatly thickened by exudation, and thrown into prominent circular folds. 
Its general color is of a dark brownish red, in many points verging upon black. At 
different points it shows the characteristic ulcers with a firm, dirty, white slough in 
the center of cach, but these have in no case attained a large size, nor any marked 
thickening nor induration of their base, and without special care in the examination
