HOG CHOLERA, OR SWINE PLAGUE.

live congestion of the malpighian tufts, is quite accurate, as it 
nas been frequently seen here. His remark that pulmonary 
lesions are not very constant or necessary, does not correspond to 
the experience of Detmers or Billings in America. 
In an outbreak among seventy-five hogs, which has been 
placed at the disposal of Dr. Billings, the pulmonary lesions have 
far exceded in intensity those of the intestines; the latter, with 
the exception of capillary congestion and the swelling of the 
mucosa, with more or less intestinal catarrh, which in some cases 
was entirely missed in the large intestines, have been entirely 
wanting in ten autopsies thus far made, the animals having died 
of oedema pulmonum. The pneumonia in hogs so far as we have 
seen it here, has been of a bronchial character, leading to casea¬ 
tion, and in some cases to necrosis; hemorrhage infarctions are 
frequent. It seldom happens that the intestinal tissue becomes 
complicated by indurated process, unless it be in very chronic 
cases; in general those tissues are reddened and swollen. 
Our necroscopical observations in the above outbreak do not 
go to confirm Walley’s assertion that ‘‘as a rule the fceces are 
either semi-solid or of a liquid consistency, as constipation has not 
only been remarked in this outbreak throughout, but in many 
others. When the intestinal lesions predominate, diarrhoea is un¬ 
doubtedly present. His description of the mottled appearance of 
the lymphatic glands, which he compares to “ the appearance of 
a ‘queen’s strawberry,”’ was also met with by us in severe cases. 
Mr. Archibald Robinson’s remarks in the discussion on Prof. 
Walley’s paper “ that in the district of Baden, Germany, inocula¬ 
tion has been successfully carried out,” show that he does hot 
know what disease the Baden investigations had to do with, or 
else has a very poor knowledge of German. The Baden investi 
tions were made by Drs. Lydtin and Schotellius in regard to the 
protective powers of M. Pasteur’s “ vaccine contre rouget,” which 
is the same disease as the German “ rothlauf ” or erysipelas of 
swine, a disease which has no pathological or etiological connec¬ 
tion with the swine plague in Germany, England or America. 
The micro-organism of this disease being a bacillus or rod-bacte¬ 
ria, while that of swine plague in both Germany and America is 
an oval body. {To be continued .)
