of bacterial spores. The terminal nodules of the smaller 

 spirochaetes are very suggestive of such a formation. 



Associated with Sp. anodonta are found chains of 

 coccoid bodies, similar in length to the spirochaetes. 

 The arrangement of the staining material in the bodies 

 of the latter, which may break up into regular portions

of about equal size, suggests that they may give rise to 

 the cocci by a process of multiple fission (Fig. 49) . * 



In this connexion it is interesting to note the occur- 

 rence of rod-shaped bodies, containing dots resembling 

 nuclei, in association with different kinds of spirochaetes. 

 Thus they were found by Krzystalowic and Siedlecki 

 along with Sp. pallida (Fig. 50) by Prowazek in connex- 



1 1 hope to publish shortly further observations supporting the 

 probability of this mode of development in Sp. anodontce.
