At least in some cases, tlie nuclei from the central 

 cell appesj? to become abnorms,! and break dovm. The cliro- 

 matin forms a ci^esent -shaped mass applied to the nuclear 

 membrane on one side (fig. 96), the nuclei swell, their 

 outlines become fa,int, and finally their contents mingle 

 with the cytoplasm. ITot all of the nuclei from the central 

 cell degenerate, and it is often difficult to distinguisli 

 tliose which remain normr.l from the sporogenous nuclei, es- 

 pecially in the older cystoca.rps, except by their position 

 in the cell. 



The mode of division of tlie sporogenous lobes seems 

 to vary considerably in different lobes. The series of 

 figures fro;.i 97 to 101 gives a fair idea of v/hat usually
