suffered from an erysipelatous inflammation. In- 

 jection of the cocci into the circulation produced 

 suppurative inflammation of the joints. Isolated 

 from the mucous membrane of diphtheritic cases. 



Streptococcus in cerebro-spinal meningitis.* 

 Cocci, diplococci, and chains have been observed 

 in the exudation of cerebro-spinal meningitis ; all 

 forms were detected in the meninges, and zoogloea 

 in the kidneys. 



Streptococcus in yellow fever Cocci '6-7 /* 

 in diameter have been observed in this disease, f 

 They occur in chains, aggregated in masses, which 

 distend the vessels of the kidney and liver. 



Streptococcus in dental caries. Two species

1. Occurs in the form of cocci, diplococci, and 

 chains, which develop very rapidly in nutrient 

 gelatine, speedily converting it into a turbid liquid. 

 They are agents of lactic acid fermentation. 



2. Occurs as very small cocci, rarely in chains, 

 which rapidly liquefy nutrient gelatine. There are 

 also associated with these, two species of micrococci 

 and a spirillum {Spirillum sputigenuni). 



Streptococcus variolse et vacciniae. Cocci, 

 5 p, in diam., singly, in pairs, and in long or short 

 chains, and colonies. They are found in the fresh
