might be easily overlooked. Tho rectum contains numerous blood extravasations and 
some considerable ulcers with the central whitish necrosed portions. 
Mesenteric glands: Almost universally enlarged and of a deep red, from congestion 
and extravasation. 
Liver: Of a very deep purplish brown, gorged with blood, but not materially soft- 
ened nor moderately friable. It is especially dark near the margin of the lobes. 
Gall-bladder : Moderately full, bile dark green and viscid. 
Pancreas: Sound. 
Spleen: Enlarged, gorged with blood, and almost black. 
Kidneys : Nearly normal as examined’ externally. Corticle substance of a darker 
red than in most of the diseased pigs, and the papillie bear black extravasations, 
punctiform and up to half a line in breadth. The right kidney contains a small cyst 
in its pelvis. 
Left supra-renal capsule is enlarged to about one-third the size of the kidney, and 
has a clot of blood and a collection of cheesy matter superposed in its anterior end. 
Inngs: Nearly normal; some congestion in the posterior lobes is evidently quite re- 
cent, and the cut surface freely exudes a frothy liquid. 
Heart: Right ventricle slightly discolored by punctiform petechiie beneath the endo- 
cardium. The great aorta contains a very firm clot, partly buffed. 
Blood under a No.10 Hartnack immersion shows no moving bacteria, but a great 
excess of granular matter.
