GONORRHOEA. 303

little groups, as seen in the figure, exactly re- 

 sembling those found in the cells of gonorrhoeal 

 pus. The photo-micrograph was made from a 

 specimen obtained by cultivating the organisms 

 found in normal saliva in an acid solution of malt 

 extract. In my paper published in Vol. II, No. 2, 

 of " Studies from the Biological Laboratory, Johns 

 Hopkins University " (Bacteria in Healthy Indi- 

 viduals), this micrococcus was incorrectly de- 

 scribed as a species of Sarcina, as " division by two 

 perpendicular partitions in such a manner that 

 multiplication takes place in two directions " is 

 given as a distinctive character of this genus (see 

 p. 96 of the present volume). 



It is well known, from the observations of 

 numerous microscopists, that pus from various 

 sources e. g., acute abscesses, surgical injuries, 

 etc. contains micrococci. 



Ogsten has given much attention to the study 

 of these, and in his report on " Micro-organisms in 

 Surgical Diseases," he gives figures of micrococci 

 which resemble very closely, if they are not iden- 

 tical with, the " gonococci " of Neisser. In his de- 

 scription of these he says : 



"In the chain-form, division occurred in only one 

 direction, through a plane midway between two given 

 poles, so that a pair of cocci growing formed a chain 

 of four ; this grew into a chain of eight. ... In the 

 grouped form, fission took place in any direction, a sin- 

 gle coccus seemingly dividing into two, three, or four 

 cocci, and a continuance of this forming the groups. 

 Many of the masses had evidently been produced by
