At the time of the passage of tlie fusion nucleus into 

 the atixiliary cell, there is in the center of the latter a 

 very large clear nucleus. This is one of the nuclei orig- 

 inally present in the auxiliary cell. Besides this, two 

 or tiiree small nuclei are freqi^.ently seen in the peripheral 

 portion of the cell (fig. 87). These are the reim^ining 

 nuclei present at the time of the organization of the aiuc- 

 iliary cell. They seem to disappear during tlie course of 

 the further development of the aiociliary cell. 



The fusion nucleus in the avuxiliary cell is of very 

 characteristic appearance. It differs from the us\Jial t^^pe 

 of nucleus in possessing tv/o chromatin-nucleoli instead of 

 one. It would seem as if the cliromatin from the male and
