KHINOSCLEKOMA 319 



organism to that of Friedlander is still a matter of doubt, and 

 the matter has been further complicated by the fact that a 

 bacillus possessing closely similar characters has been found to 

 be very frequently present in ozoena, and is often known as the 

 bacillus ozcence. The last-mentioned organism is said to have 

 more active fermentative powers. From what has been stated 

 it will be seen that a number of organisms, closely allied in their 

 morphological characters, have been found in the nasal cavity 

 in healthy or diseased conditions. There is no doubt that 

 rhinoscleroma is a specific disease with well-marked characters, 

 and it is quite possible that one member of this group of 

 organisms may be the causal agent, though indistinguishable 

 from others by culture tests. There is, however, a tendency on 

 the part of recent investigators, e.g., Perkins, to consider the 

 "bacillus of rhinoscleroma" to be identical with the pneumo- 

 bacillus, and its presence in the affected tissues to represent 

 merely a secondary invasion. The subject is one on which more 

 light is still required.
