oedematous. The kidneys are large, soft, and red or blackish in 
color. The mucous surface of the renal pelvis is ecchymosed and 
covered with a yellowish mucus, and the bladder is always filled 
with a dark reddish urine. The liver is enlarged, pale, marbled 
and soft, and the spleen swollen and blackish, and its pulp 
softened. 
There is always present a characteristic bacteria, round, very 
small, divided in two by a median striae, and often, in four, 
transversally by another. This microbe, which resembles the 
gonococcus , often forms dipplococci. It colors with the aniline 
bases, and imperfectly with the method of Gram, and is discol¬ 
ored if heated by alcohol. It is easily seen in the dried prepara¬ 
tion, or upon sections colored first with the blue of Loefiler, and 
then with a concentrated alcoholic solution of the same color, and 
again with aniline oil and xylol. If colored with the violet of 
methyl, it is larger and has a square form, the two individuals 
forming the dipplococcus being united at their angles by a thin 
thread. 
In the heart and blood vessels they are free, adherent to the 
red corpuscles, or situated inside of them. In the hemorrhagic 
oedema, and in the kidneys, they are more numerous, and their 
presence in the red corpuscles is then easily made out. The red 
corpuscles are, however, altered, and become less colored and less 
resisting. Upon section of the stomach, and especially where 
the ulcerations exist, the superficial necrosed tissue will not color. 
Numerous bacilli of various kinds are found in the glands. The 
diplococci are in the dilated superficial small vessels, which are 
filled with them. In the mesenteric glands, large masses of bac- 
terias, smaller than those of the blood vessels, form a plasmatic 
network, in groups of four or more individuals. The liver, usual¬ 
ly, is free from bacterias. In the central parts of the lobes, the 
hepatic cells are homogeneous and yellowish, and the intro 
lobular capillaries are full of broken cells, highly colored. The 
pulp of the spleen contains many large cells, filled with yellow 
pigment, and the bacterias are often found in the center of the 
red corpuscles, and at the periphery of the blood vessels. The 
capillaries of the kidneys and the glomerulae are much dilated,
