79. — 7. An Eaklt Metathase. 

 The two halves of each chromo- 

 some are separating from one 

 another in the form of V-shaped 

 secondary chromosomes ; the 

 achromatic spindle is now quite 

 a marked feature. 



8. A Latkr Mktaphase, 

 showing the two systems of 

 secondary chromosomes travel- 

 ling away from one another 

 towards the poles of the 

 spindle. 



Fig. 80. — 9. A stage where the two 

 systems of daughter-chromosomes 

 here almost reached the poles of 

 the spindle (late metaphase). The 

 line of dots along the middle of 

 the spindle indicates the line 

 along which the cell-plate will 

 form.
