I 
marked in the cases of hog cholera. The kidneys, highly 
hyperemic, presented no microscopic lesions. The bladder 
was almost always empty. Nothing abnormal in the other 
organs. 
The blood, as well as the various viscera (spleen, liver, 
kidneys), contained numerous microbes, their number being 
often much higher than that of the blood corpuscles. Simple 
coloration with the blue of Loeffler, with the aqueous solu¬ 
tion of the methylene blue and the thionine, as well as the 
double coloring with eosine and Loeffler blue, has given 
handsome preparations. I have made at each post mortem 
the examination of the blood and that of the cultures, one 
on gelosis and the other on bouillon. 
The lesions that I have just described are those that are 
seen in fresh rabbits, dead one or two days after the inocu¬ 
lation. 
In the cases where the disease lasts several days, either 
on account of the weak virulency of the injected liquid, or 
because the rabbit is only incompletely vaccinated, various 
other lesions are seen, but not with the same constancy. 
The peritoneal serous is strongly injected, and at times 
presents, especially in the inferior region of the ascending 
colon, numerous small ecchymosis, which are not so frequent 
in the small intestine. 
In the cases of extension of the local oedema of the ear, 
the surrounding part of the poll or of the face was ordi¬ 
narily tumefied and presented a large subcutaneous abscess; 
in several instances I found a purulent pleurisy on the side 
corresponding to that of the injected ear, with small ab- 
cesses in varying number in both lungs, and with partial 
hepatization of the pulmonary tissue, principally in the in¬ 
ferior lobes. Cultures with these abscesses or the liquid of 
the pleuro were always pure. 
Once or twice, in cases progressing very slowly, I have 
seen with the pleurisy a purulent peritonitis, and I have also 
found, though seldom, it is true, a sero-fibrinous peritonitis. 
The presence of miliary abscesses of the liver was noticed 
four or five times, and twice did they exist in the spleen.
