DESCRIPTIONS OF PATHOGENIC BACTERIA. 173 



mice and rabbits ; it stained by Gram's method. 

 Another capsule bacillus has been cultivated 

 by Weichselbaum from a case of endocarditis 

 with purulent infarction, one by Mandry out 

 of bronchial mucus, and another by Kockel 

 from suppurated hepatic cysts and meningitis. 

 Fasching cultivated a capsule bacillus from 

 the purulent mucous membrane of the naso- 

 pharyngeal space, and Abel one from ozaena. 

 All of these reports of the discovery of capsule 

 bacilli are not as complete as they should be, 

 but R. Pfeiffer succeeded in cultivating from 

 the peritoneal exudate of a guinea-pig a cap- 

 sulated species which actually invested the 

 blood and tissue juices of the animal under 

 experiment with a ropy quality. Chiari, in a 

 case of cystitis in man, which led to suppurating 

 inflammation of the kidneys, and from that to 

 pyaemia, found a capsulated bacterium, gener- 

 ally occurring in rod-form ; it stains by Gram's 

 method. This bacterium is fatal to white mice, 

 and causes pyaemia on subcutaneous and intra- 

 peritoneal inoculation : guinea-pigs, inoculated 

 subcutaneously, develop extensive suppura- 

 tion ; and, when the inoculation is intraperi- 

 toneal, peritonitis and general infection result ; 

 rabbits, inoculated subcutaneously develop 

 suppuration, when inoculated intravenously, 

 septicaemia and when the kidneys are in-
