encountered that is packed with them. Occasionally 

 masses of these small bodies will be seen lying free in 

 the pus. (See Fig. 56.) The majority of the pus-cells 

 do not contain them. 



These small, round, or oval bodies are the so-called 

 "gonococci" discovered by Neisser, and more fully 

 studied subsequently by Bumm, to whom we are in- 

 debted for much of our knowledge concerning them. 



As the name implies, this organism is a micrococcus,

and as it is commonly arranged in pairs (flattened at 

 the surfaces in juxtaposition) it is often designated as 

 diplococcus of gonorrhoea. It is always to be found in 

 gonorrhceal pus, and often persists in the urethral dis- 

 charges and secretions far into the stage of conva- 

 lescence. It is not present in inflammatory conditions 

 other than those of gonorrhoeal origin. 



It is easily detected microscopically in the secretions 

 of acute gonorrhoea. In secondary lesions and in very 

 old, chronic cases it is difficult of detection and fre-
