2l6 X -^!V BACTERIOLOGY. 



Koch.* Ellipsoidal cocci *8 i JJL in largest diam. 

 The disease was produced by the injection of putrid 

 meat infusion. After death slight oedema was 

 noted at the site of injection, slight extravasation of 

 blood, and great enlargement of the spleen. No 

 emboli or peritonitis resulted. Masses of cocci 

 were found in the capillaries of different organs, 

 especially in the glomeruli of the kidneys. Rabbits 

 and mice inoculated with/ blood from the heart 

 proved susceptible to the disease. 



Micrococcus of pyaemia in rabbits, 

 Koch.f Round cocci and diplococci "25 p, in 

 diam. The disease was produced by the subcu- 

 taneous injection in a rabbit of distilled water, in 

 which the skin of a mouse had been macerated. 

 At the autopsy there were found great infiltration 

 around the site of injection, peritonitis, and accu- 

 mulations in the liver and lungs ; in short, the 

 appearances of pyaemia. In the capillaries of the 

 organs examined, masses of cocci were observed 

 enclosing blood corpuscles (Fig. 74). Fresh in- 

 oculations in rabbits with exudation-fluid, or blood 

 from the heart, reproduced the same disease. 



Micrococcus of progressive suppuration in 

 rabbits, Koch.J Cocci only about "15 JJL in diam., 

 principally in thick zooglcea. The disease was 

 induced by the injection into rabbits of decom- 

 posing blood. At the place of injection a* spread-
