210 BACTERIOLOGY. 



Cocci 1*5 //, in diam., similar to gonococci. 

 They form lemon-yellow colonies on plate-cultiva- 

 tions. Isolated from blennorrhceic pus and from 

 dust from the air. 



Diplococcus albicans tardissimus, Bumm. 

 Cocci morphologically identical with gonococci. 

 They grow extraordinarily slowly on gelatine. 

 They were isolated from urethral pus. 



Micrococcus subflavus, Bumm. Cocci mor- 

 phologically resembling gonococci. Cultivated on 

 nutrient gelatine, they form whitish dots which 

 become gradually greyish and then yellow in 

 colour, and confluent. They were observed in 

 lochial discharges and vaginal secretions. 



Micrococcus albicans amplus, Bumm. 

 Cocci in pairs and tetrads similar to gonococci, 

 but considerably larger. Found in vaginal secre- 

 tions.
