SYSTEMATIC AND DESCRIPTIVE. 2OJ 



autopsy greyish nodules are found in the lungs, 

 liver, spleen, and kidney ; in and around the 

 capillaries of these nodules, and in the blood of the 

 heart, the cocci are found in great numbers in 

 zoogloea, and more rarely in chains. Inflammatory 

 change in the surrounding tissue is absent. 



Streptococcus bombycis, Bechamp (Micro- 

 zyma bombycis). Oval cocci *5 /x in diam., singly, 

 in pairs, and chains. They occur in the contents 

 of the alimentary canal, and in the gastric juice of 

 silkworms suffering from "flzcherie" (" Maladie de 

 mortsblancs" " flaccidezza" " schlafsucht"). 



Streptococcus insectorum, Burrill. Obtusely 

 oval cells, 7 i p. long and -55 p, broad, singly, 

 in pairs, chains, or zoogloea. They were detected 

 in the digestive organs of the chinck-bug (Blissus 

 leucopterus) when suffering from a certain contagious 

 disease. 



Streptococcus viscosus, Pasteur. Globular 

 cells *2 p, in diam., singly or in chains. These and 

 allied forms have been considered to be the cause 

 of mucoid fermentation in wine and beer * (vin 

 filant) biere ma lade). 



Streptococcus coronatus (Micrococcus corona- 

 tus, Fliigge). Cocci i /x, in diam., singly, in short 

 chains, and in zoogloea. In plate-cultivations the 

 colonies have a characteristic halo, formed by the 

 liquefaction of the gelatine around the colony. 

 Isolated from the air.
