424 Cerebrospinal Meningitis 



cerebrospinal meningitis was accidental, as inoculations 

 into animals showed its pathogenic power to be very limited. 

 The careful studies of Jager,* Scherer,f Councilman, and 

 Mallory and Wright J (embracing 55 cases, in which the 

 cocci were found by culture or by microscopic examina- 

 tion in 38), and of Flatten, Schneider, Rieger, Schmidt,! 

 G6ppert, Flugge, von Lingelsheim, and others. Bes- 

 redka|| and Flexner** have, however, shown the diplococcus 

 of Weichselbaum to be, without doubt, the specific organism.

Distribution. The distribution of Diplococcus intra- 

 cellularis in nature is as yet unknown. It has been found 

 in cerebrospinal meningitis by those who have looked for 

 it, twice has been found in the nose in coryza by Scherer, 

 has been found in the conjunctiva by Carl Frankelf f and 

 Axenfeld, J t and in the purulent discharges of rhinitis and 

 otitis by Jager. 



Morphology. The micro-organism is a biscuit-shaped 

 diplococcus having a great resemblance to the gonococcus.
