680 SOME ACCOUNT OF A SWINE PESTILENCE. 
when there had been diarrhoea or dysentery, presented in all 
instances evidences of inflammation ; in patches it was red, 
thickened, sometimes softened, and occasionally ulcerated ; 
when there had been dysentery there was generally bloody 
mucus found in the large intestines. The bladder generally 
contained urine ; sometimes its mucous membrane was in- 
flamed, and in one instance there was an effusion of blood into 
this organ. In a large number of cases. Dr. Sutton found 
evidences of peritoneal inflammation, such as redness of this 
membrane, effusion of turbid or bloody serum, adhesions be- 
tween the intestines, and between the intestines and sides of 
the body. In three instances blood was effused into the peri- 
toneal cavity, in one instance more than a quart ; it appeared 
in this case to come from the liver. The liver was occasion- 
ally the seat of this inflammation, not only in its investing 
membrane, but in the parenchyma ; sometimes there were 
abscesses, and in one instance portions of it were gangrenous. 
The lymphatic glands were generally of a dark red colour, 
frequently resembling clots of blood. This disease of the lym- 
phatic glands was of common occurrence. 
The lungs were frequently the seat of this inflammation, 
portions of one or both presenting different appearances, from 
simple congestion to complete hepatisation ; sometimes there 
was ulceration, and frequently there was a turbid or sero- 
purulent or bloody effusion into the pleural cavity; and often 
there were extensive adhesions between the lungs and pleura 
of the ribs. At first, Dr. Sutton was inclined to believe this 
malady to be a form of pleuro-pneumonia, but his after 
observations led him to the fact, that the inflammation was 
not uniformly confined to any organ. In a number of in- 
stances, the mucous membrane of the bronchi was deeply 
inflamed, and the inflammation extended to the trachea and 
larynx. In several instances the larynx w r as inflamed, re- 
sembling laryngitis. One animal, that had great difficulty 
in breathing and could make no noise, Dr. Sutton caused to 
be knocked on the head, and on examination he found the 
mucous membrane of the larynx and epiglottis inflamed and 
swollen ; also the tongue was swollen. There were evidences 
in several instances of pericarditis, which produced adhesions 
between the heart and pericardium. The brain, from the 
difficulty of opening the skull, w r as examined only in one in- 
stance ; it w T as found healthy, although Dr. Sutton feels con- 
fidence in its being frequently the seat of the disease. 
In relation to the spread of the disease, all the facts yet 
ascertained go to prove that it is propagated by contagion. To 
prove this, Dr. Sutton suggested to the Messrs. Graffs, ow ners
