1 Very similar to the bacillus of chicken cholera, but whereas the latter is pathogenic for 

 fowls and pigeons and not for guinea-pigs, the former is almost without effect on fowls and 

 pigeons, but acts very virulently on guinea-pigs. Giinther, p. 262. 



- Rouget des pores. Probably identical with the bacillus of mouse septicaemia.
