a diagnosis certain, but these lesions are sometimes very slight, 
and an examination of the intestinal tract may be necessary to 
determine whether an incipient pneumonia or false membrane 
present, in a given animal, is due to cholera or swine plague, or 
other causes. The hsemorrhagic lesions are often not conspic¬ 
uous and may be readily overlooked when hogs are being 
slaughtered at the rate of 200 to 5^^ per hour. Swine plague 
is usually manifested by a congested condition of the skin 
covering a large-area, either one-half or two-thirds of the entire 
carcass, giving it the appearance of a deep red blush. The in- 
ternal lesions are most pronounced in the lungs, being a form 
of pneumonia in which yellowish points are discerned, these 
points being necrotic spots or centres. The serous surfaces of 
the lungs as well as all other serous surfaces may be covered 
with a fibrinous exudate either in a thin layer or in many lay¬ 
ers, and when the abdominal viscera is the region more gen¬ 
erally involved, all of the viscera are agglutinated together. 
This condition ought readily to be discriminated from simple 
peritonitis, pleuritis or pericarditis, by involvement of the serous 
surfaces in other parts of the body and by the characteristic ap¬ 
pearance of the lungs and skin. A diagnosis of hog cholera or 
swine plague should always mean condemnation of carcass and 
viscera. 
Swine infested with cysticercus cellulosae are found occa¬ 
sionally. In the few cases I have seen, cysticerci were present 
in great number, pervading all the voluntary muscular struc- 
tures and the heart. When found elsewhere the cysts were im¬ 
perfectly developed. They appear as little sacs of water abou! 
cne-fourth of an inch in diameter, lying upon and wedged be¬ 
tween the muscular fibres. E^ach sac contains a white mass 
about the size of a millet seed (o. tapeworm head) which projects 
inward from the cyst wall. Flesh containing these cysts is 
commonly denominated measly pork and is the source of tape¬ 
worm {tcmid solu 7 }i^ in man. Of course the flesh would be ren¬ 
dered harmless if thoroughly cooked, but would remain dis¬ 
gusting, and should be condemned.
