geen. 
_ Digestive organs: Mouth and throat healthy. 
. Guttural lymphatic glands: Enlarged and somewhai congested. 
_ Stomach: Moderately fall; of a deep brownish red along its great curvature. 
Small intestine: Slightly congested in patches; contains twelve ascarides. 
Large intestine: Nearly normal. 
Mesenteric lymphatic glands: Enlarged and slightly congested. Their surface presents 
clear, glistening, rounded masses like pins’ heads. Jnguinal glands have the same 
' .- eharacter. 
Lung: Isolated lobulettes are dark red and solid; at some points the interlobular

Post-mortem examination.—Skin: Margin of snout for one-half line deep of a dark 
brown, and apparently without vascularity or life. Beneath this is a red congested 
e. 
Ears: peeply blotched with dark red and purple macule, each about one-half inch 
in diameter, buf to a great extent confluent, so as to form extended lines and patches. 
Stump of tail maculated. Perineum and adjacent parts of hip of a deep purple. 
Digestive organs: Tongue with a whitish fur. On the center of its dorsal surface is 
a dark spot about two lines in diameter, which is found to cover a considerable ex- ' 
travasation and clot on the muscular substance. Glandular follicles on the lower sur- 
face of the soft palate fillea with a soft yellowish puriform mass. : 
Submaxilliary lymphntie glands: Greatly enlarged and of a deep purple. Guttural 
glands also blood-stained and moderately enlarged. 
tomach: Full, very fetid, not sour. Great curvature has its mucous membrane much 
congested with numerous black spots of extravasation projecting beyond the general 
surface. In the left cul de sac the ingesta next the mucous membrane is of a dark 
baked appearance and firmly adherent to the mucous membrane, the epithelial layer 
of which comes off with it. It has evidently been adherent for some time. 
Smallintestines : Havelarge tracts of congestion, and in the duodenum and commence+ 
ment of the jejunum are ten ascarides. Seven ascarides have made their way into the 
gall duct and the different lobes of the liver, but none in the cystic duct nor gall- 
bladder. The biliary duct is greatly distended and coated with a layer of yellowish- 
green biliary coloring matter. 
, ie SEReeoal valve: Has its margin of a deep grayish-black and its follicles en- 
arged. 
Lhe large intestines : Are throughout black from pigmentary deposit, the blackness 
being especially marked on the agminated gland, extending from the ilio-cecal valve 
on the colon. Many round blackish elevations are scattered over the length of the 
colon, appearing like enlarged solitary glands. On some parts of the colon the dark
