Post-mortem examination.—Has been purging; feces fetid and bright yellow. 
Skin: Nearly covered with black spots of from one to two lines in diameter, and 
evidently formed by sloughs or small necrotic patches of cuticle, infiltrated with blood 
and dried up. The median line of the belly between the rows of teats is almost de- 
void of these spots. 
A purple rash in spots averaging one line across exists in different parts of the body, 
but is most abundant on snout, ears, buttocks, root of tail, and limbs, especially on 
the lower parts and innersides. At certain points, as on the pendant half of the ears, 
on the hocks, in the region of the arms, and on part of the snout, there is a uniform 
leaden discoloration. ‘The inner sides of the arms have similar but more circumscribed 
patches. > 
Digestive organs: A deep purple blush extends along the line of papillz on the right 
border of the tongue. Similar spots exist in the posterior nares. Salivary glands are 
pale and normal. The guttural lymphatic glands have spots of congestion on their 
surface, but not extending into their interior. 
Abdomen: No effusion. Three hydatids are found attached respectively to the 
posterior surface of the stomach, to the back of the liver, and to the mesocolon. 
Stomach: Full of undigested food, yellow at pylorus. No marked congestion nor 
softening. No parasites. 
Small intestine: Duodenum without extra vascularity: its epithelium gray, pig- 
mented, and easily detached. Jejunum and ilinm had circumscribed spots of conges- 
tion one-half inch in diameter on an average, and in one case slightly eroded. 
Large intestine: Ceeeum presents three ulcers, each one-fourth inch in diameter, hay- 
ing a circular elevated mass of dirty-white deposit, apparently non-vascular, and a 
very slightly reddened base. The matter on the surface of the ulcer consisted of cells, 
round, angular, and of other forms, much granular matter and myriads of round and 
linear moving bacteria. None of these ulcers appear to be situated on the solitary 
glands. The same remark applies to the congestions and erosions of the small intes- 
tines. Colon and rectum natural. 
Parasites: The small intestines contain three ascarides (A. Suilla). The colon con- 
tains a young whip-worm (tricocephalus crenatus). The coats of the intestines at the 
points of congestion and elsewhere were carefully examined for parasites, but without 
result. The muscular tissue of the diaphragm was also examined in vain. 
Liver: Two small cysts, each one-half line in length, exist on the middle lcbe. They 
had thick fibrous walls and liquid contents in which the microscope detected cell forms.
