tumid and tender, the animal expresses great pain when compelled 
to move, and prefers to lie prone upon the belly. There is often 
great difficulty of breathing, which is more or less spasmodic, and 
attended with severe cough; not unfrequently there is hemor¬ 
rhage from the nostrils and swelling of the parotid glands. 
Through the febrile, or acute inflammatory stage, there is consti¬ 
pation, which is afterwards followed by diarrhoea; at first the 
evacuations may be destitute of bile, then bilious, and very soon 
dark colored, or blood-stained and very foetid. Finally, locomo¬ 
tion becomes difficult, unsteady, and perhaps spasmodic, or the 
posterior extremities are entirely paralyzed. Death may occur 
within a few hours, and during the congestive stage as already 
stated; it may occur in a few days from the effect of inflamma¬ 
tion, or in one or two weeks from exhaustion, from peritonitis, or 
from effusion. 
Post-mortem .—On examination after death, the cavity of the 
abdomen is often found to contain a few ounces of serum, and 
sometimes fibrinous exudations. The liver is not materially 
changed in size or texture, but often has a yellowish or ashy 
color; occasionally it was found greatly engorged. The spleen 
was enlarged in nearly half the cases examined, sometimes to a 
great extent, and so disorganized that when the capsule was rup¬ 
tured the grumous contents would escape. This disorganized 
condition of the spleen, as might be expected, was greatest when 
the blood showed most change. 
The stomach often contained undigested food, the mucous 
membrane was usually congested, but rarely showed as decided 
evidence of inflammation as other portions of the alimentary 
canal. The small intestines, on their external surface, presented 
patches of deep discoloration; occasionally they would be glued 
together by limphy exudations. The mucous lining showed gen¬ 
eral congestion, and inflammation in patches; sometimes tumefac¬ 
tion and exudation would be almost confined to the aggregate and 
solitary glands, which in some cases were covered by dark colored 
crusts, or where these had sloughed off, patches of ulceration were 
seen. Frequently, however, the inflammation and ulceration 
affected glandular and other portions indifferently; or the whole
