, DISEASES OF SWINE AND OTHER ANIMALS. 343 
considerably enlarged. One-fourth of right and one-fifth of left lobe 
of lungs hepatized; the rest gorged with blood-serum or exudation. 
Ceeum and colon agglutinated to each other; czecum also adhering to 
peritoneum. Mesenteric glands very much enlarged; right spermatic 
chord ulcerated. (Pig had been castrated a few weeks before it con- 
tracted the disease.) Extensive morbid growth, in process of decay, in 
cecum, and also a large number in colon. Some exudation on lower 
surface of spleen. Ulcerous decay in mucous membrane of anterior 
portion of stomach, and wine-colored infiltration and extravasations of 
blood in mucous membrane of pylorie portion of same intestine. 
Autopsy of pig B—Some redness between hind legs and on lower sur- 
face of the body; greenish mucus oozing from the nose; axillary and 
inguinal glands very much enlarged; ribs deficient in organic substances, 
at any rate very brittle; both lungs spoited all over, indicating plainly 
capillary embolism in early stage of development; hepatization limited, 
just commencing; lymphatic glands in chest very much enlarged; the 
heart, but especially the auricles, very much congested ; auricles almost 
black; smali quantity of straw-colored serum (not exceeding two ounces) 
in thoracic cavity, and still less in pericardium. In the abdominal eay- 
ity mucous membrane of anterior part of stomach wine-colored; some 
diffuse morbid growth, in process of decay, in posterior (pyloric) portion 
of same membrane. No food whatever in stomach and intestines; bile 
thickened, semi-solid; no ulceration nor any morbid growth whatever 
in cecum, colon, or any other intestine. 
Results of post-mortem examination of experimental pig No. V1.—Deeay- 
ing blotches or nodules of the size of a five-cent piece and smailer on 
skin of lower surface of body and between the legs; right spermatic 
chord ulcerated, and an abscess the size of a hen’s egg in right side of 
scrotum. Intérnally all lymphatic and mesenteric glands enlarged; 
anterior portion of both lungs everywhere, with their whole external 
surface, and posterior portion at some places adhering (coalesced) to the 
costal pleura; numerous smaller and larger embolic tubercles, present- 
ing the appearance of incipient abscesses, in anterior portion of both 
lobes of the lungs, but more numerous and more developed in right lobe 
than in the left; remainder—posterior parts of both lobes—gorged with 
exudation; small quantity of straw-colored serum in the chest and in 
the pericardium. In abdominal cavity, liver rather hard (sclerotic), its 
connective tissue apparently hypertrophied. One small tape-worm, not 
over one and a half inches long, in jejunum, and numerous small, incip- 
ient morbid growths or ocher-colored decaying nodules in cecum. (See 
photograph, Plate Il.) No other morbid changes. 
Besides these numerous morbid changes, which must be looked upon 
as products of the morbid process of swine-plague, some species of en- 
tozoa, a few of which have already been mentioned, have occasionally 
been met with; but as their presence is merely accidental, that is, has 
nothing whatever to do with the disease in question, a brief mention of 
this occurrence will be sufiicient. Strongylus paradoxus has been found 
in small numbers in the bronchial tubes of a few pigs in one herd only— 
Mr. Bassett’s. Trichocephalus crenatus (whip-worm) has been found in 
small numbers in the blind end of the cecum of four animals, belonging 
to two different herds. A small tape-worm was once found in the 
jejunum, as has been stated, and a few other entozoa (nematoids) were 
found in four or five instances in the choledochus, gall-bladder, and 
hepatic ducts (in one case as many as twelve worms), and twice in other 
intestines. 
What I have so far related was comparatively easily ascertained. Nu-
