200 CLASSIFICATION OF THE MICEO-ORGANISMS. 



cocci, and in the sections through the urethral mucous 

 membrane numerous cells filled with cocci were found. 

 This case is not quite free from objection, because later 

 experiments have shown that no growth of the cocci 

 occurs on nutrient gelatine ; perhaps, therefore, the 

 positive result was obtained by cocci which had not 

 grown in the cultivation but had been carried over 

 in the inoculations, and had remained alive; this is 

 not at all improbable, because large quantities were 

 employed in the inoculation from the pus, and in 

 the subsequent reinoculations, and also because the 

 fourth generation was employed for the infection ex- 

 periment. A second inoculation experiment was made 

 by Bumm on the healthy urethral mucous membrane 

 of a woman, and in like manner with a positive 

 result ; the second generation of a cultivation on blood 

 serum was employed. Here also, in spite of the 

 fact that pus cells could not be found in the cultiva- 

 tion on microscopical examination, the objection is 

 possible that perhaps cocci were carried over from the 

 secretion, especially as the first inoculation on the 

 artificial soil was always made with relatively large 

 quantities.* 



Occurrence of The occurrence of the gonorrhoea coccus is, according 

 coccus! a to the opinion of all trustworthy observers who are ac- 

 quainted with the saprophytic forms similar to the gono- 

 coccus, limited to gonorrhoeal affections of the urethra 

 or bladder, of the cervix uteri, &c., and to the specific 

 blennorrhoea of the conjunctiva. The characteristic 

 cocci were also found in the purulent effusion into a 

 knee joint in a case of gonorrhreal inflammation of the 

 joint (Petrone and Kammerer). 



Micrococcus sulflavus. 

 (Yellowish-white diplococcus of Bumm.) 



Micrococcus Similar to the foregoing, frequently observed in the 

 similar to the lochia and in vaginal secretions, and perhaps also 



gonorrhoea 



coccus. * Bumm has since obtained a successful result by inoculation of a 



twentieth cultivation.
