Fig. 6. The first stage in the amitotic elongation of the chromoblast, x 3,000. 
Fig. 7. The second stage in the division, x 3,000. 
Fig. 8. The third stage. The chromoblast is constricted in the middle and is still elongating, 
x 3,000. 
Fig. 9. The fourth stage. The two daughter chromoblasts are now joined only by a thread, 
x 3,000. 
Fig. 10. The fifth stage. The two daughter chromoblasts have separated and have assumed 
the spherical form once more, x 3,000. 
Fig. 11. The sixth stage. The nuclear membrane has become more constricted and the whole 
nucleus longer. The chromatin on the membrane has regained its original density, x 3,000. 
Fig. 12. The two daughter nuclei are about to separate. x 3,00c.
