130 PROTISTS AND DISEASE 



At the close of the chromidial stage Prowazek and 

 subsequent writers found that the new nuclei appeared in 

 the old nuclear cavities. In this section all the chromidial 

 parasites are finely granular throughout, Fig. 35, 6, and no 

 remains of nuclear cavities can be traced ; also the nucleated 

 state is reconstituted by the fusion of granules at equi- 

 distant foci, Fig. 35, 7 : a good example of free nucleus- 

 formation. 



Opinion as to the relative position of this group is in 

 favour of its being placed between the Chytridians and the 

 Mycetozoa proper.
