 In pus or culture they are of this figure, but in the 

 former they are characteristically lying within the 

 pus cells between the wall and the nucleus, but not 

 within the latter. Free pairs are also seen, but it is 

 unwise to name them when not in the cells, because 

 other cocci may resemble them. There is a resem- 

 blance between these organisms and those of meningitis 

 (p. 92), but the clinical differentiation is not difficult, 

 since the diseases are easily separated.

The gonococcus does not stain by Gram's method, 

 a quite important criterion for the bacteriologist. It 

 is cultivated with difficulty. For purposes of growing 

 it in the laboratory a broth or jelly must be used to 

 which has been added some blood or blood serum or 

 fluid from a hydrocele or the peritoneum. It grows 

 best in the presence of free oxygen, a curious fact,
