 characterized by one or more highly refractive endochromatic 

 granules, which probably serve as nourishment for the chromi- 



FIG. 5. Two daughter-cells of an auxocyte connected by a spindle bridge. There are eight acces- 

 sory archosomes at the apex of as many fiber cones. Two archosomes are connected by a 

 central spindle. In the latter is seen a mid-body consisting of three condensation granules. 

 The chromosomes are being regenerated, and the chromoplasts appear at the angle of the 

 chromosomes instead of at the apex, as in the last cell stage. In one nucleus are seen five, in 

 the other six chromoplasts with endochromatic granules. Between the true nuclear membrane 

 and the false membrane is an open space caused by the false membrane being pulled away by 

 the fiber cones. 



oles. The chromoplasts serve as landmarks by which the posi- 

 tion of the chromosomes can be ascertained with great accuracy.
