An examination of the blood, secretions and tissues of this 
uimal, gave the characteristic bacteria, which also developed in 
ultivations from the spleen. It should be mentioned that all of 
he sick hogs in the herd, from which this came, were character- 
zed by the most obstinate constipatioh, and that the popular name 
1 hog cholera ” is not therefore a suitable nomenclature for this 
lisease; and that the name swine plague is much more appropri- 
tte, though that given by Klein seems to correspond more exactly 
o the pathological lesions. Hence, I think, that veterinarians 
;hould speak of it professionally as pneumo-enteris suis contagiosa. 
As to whether it is a contagious or infectious disease in the 
strict sense of the term, there is still room for some doubts, for, 
iccording to JDr. Billings’ views, a strictly contagious disease is 
>ne which has its origin, so far as we know, in an animal organ- 
sm of a given species, and never outside of it; but may be trans- 
nissable from animal to animal of the same species, and in some 
iases to others i. e. glanders, rabies, syphilis, while a strictly in¬ 
fectious disease is one bound on a locality in which an animal or¬ 
ganism has to be in or go to in order to be infected. The in¬ 
fected animal cannot transmit the disease to other animals, but 
3 an carry the infectious ^elements in its body, and thereby infect 
Dther localities through its excretions, which may then become 
ientres of infection to other susceptible animals, i. e ., Texas fever, 
cholera, anthrax, yellow fever. There is some evidence that swine 
plague may belong to the latter class.. In an autopsy made on the 
28th of October, 1886, we found the lesions almost entirely re¬ 
stricted to the organs of the thoracic cavity and the throat, with 
the exception of a slight swelling and redness of the mucosae of 
the alimentary tract, although the various lymph glands of the 
abdominal cavity presented the appearance above described. The
