btes Concerning Insufficiently Elucidated 

 Diseases Which Perhaps Depend

Some diseases which are probably produced by fission- 

 fungi, as syphilis, are treated briefly in the text; some 

 others are suited only to a discussion in an appendix, 

 because that which is known regarding their etiology is 

 either very uncertain or so incomplete that the insertion 

 of the micro-organisms in a system is not possible. 



Phlyctenular (Scrofulous, Eczematous) Ophthal- 

 mitis. 



In contrast to the authors who would recognize in the 

 Micrococcus pyogenes alone the cause of the above-men- 

 tioned inflammations of the eye developing upon a scrofu- 

 lous substratum, a number of investigators have shown 

 that in carefully selected uncomplicated cases, in a major- 

 ity of the examinations, no micro-organisms were to be
