 They are probably identical with bacteria found in 

 healthy faeces. They were isolated from some cases 

 of cholera at Naples.

Bacterium of Rhinoscleroma (Bacillus of 

 Rhinoscleroma, Cornil and Alvarez *). Cocci and 

 short rods, 1*5 3 p in length, -5 '8 ^ thick. 

 Deeply coloured points or granules may occur in 

 the course of the rods when stained, but it is very 

 doubtful whether these can be considered as spores. 



FIG. 78. BACTERIA OF RHINOSCLEROMA, x 140x5. Encapsuled cocci, diplo- 

 cocci, and short and long rod-forms [after Cornil]. 



The bacteria are encapsuled, the capsule being round 

 when enclosing a coccus, and ovoid when enclosing 

 a rod (Fig. 78). The capsule is composed of a tough 

 resisting substance; two or more capsules may 

 unite by fusion, enclosing two or three, or a great
