94 PROTISTS AND DISEASE 



if such were the prevalent mode stages between elements 

 like Fig. 24, d and the binucleate stage would be common, 

 and they are not ; I am led to consider the possibility of a 

 second mode of division of the primary nucleus consisting 

 of a simultaneous breaking of the one nucleus into many." 



I think the puzzling bodies are nuclei usually originating 

 in a chromidium, as I saw it in the living state in syphilis. 

 The following account is copied from Part II, but was first 

 published in 1907. Before passing to this description I 

 would again refer to the nucleus of S. decipims, Fig. 24, a, 

 remembering that the nucleus there depicted corresponds 

 with the soral nucleus in 8. endobioticum, Fig. 21. We see 

 that, instead of dividing, the nucleolus of 8. decipiens as 

 seen by Stevens became plasmodial and was streaming 

 into the cytoplasm, where new nuclei were formed as they 

 are from generative chromidia. I have seen similar nuclei 

 or bird's-eye bodies form in molluscum corpuscles after 

 they have been in water for some days. 



Living Bird's-eye Bodies in Syphilis. The production of 

 these bodies in living intracellular parasites in syphilis is 

 so important that I will insert the account almost as it 

 stands in Part II ; the observation was made long before 

 the introduction of rapidly acting arsenical compounds in 

 the treatment of syphilis. 



The groups of oscillating granules which I saw associated 

 with the formation of bird's-eye bodies would probably be 

 equivalent to the asters Stevens described in Synchytrium.
