male nucleus with 22 distinct chromosomes proceeds toward the 
female nucleus, which is in the resting condition (figs. 30, 31), 
until the male and female nuclei touch (fig. 32). The male 
nucleus is represented only by 22 crowded chromosomes closely 
applied to the periphery of the female nucleus (fig. 33); each 
chromosome of the male nucleus enters into the female nucleus (fig. 
34); and finally each chromosome becomes vacuolized and occupies a 
part of the female nucleus (fig. 34). Later, the fusion nucleus shows 
no place-distinction of network of both male and female origin. 
It is a question whether 
the reticula of male and 
female origin do occupy 
distinct places, lying side 
by side in the fusion nu- 
cleus, or whether they 
intermingle and resume 
their individuality at the 
time of chromosome for- 
mation. In any event, 
the fusion nucleus passes 
into a complete resting 
condition, with chroma-
