and begin to have a much more regular arrange- 

 ment. In 6, the filament, which appeared united 

 in the preceding phase, increases in calibre and 

 divides itself into apparently equal parts in a 

 species of hooks in the form of V or U. 



In phase 7, we see an extraordinary movement, 

 and not only is it suggestive of the regularity in 

 the phenomena of crystallisation, but it seems to 

 me a greater proof of the regularity of the rhythms, 

 as it treats of a substance of a much more com- 

 plex composition, and therefore of a more com- 

 plicated mechanism. In this phase the surprising 

 phenomenon is the arrangement of all the meshes 

 which seemed in disorder in the preceding phase, 

 and now are disposed in a regular fashion round 

 centre of the cell. 



In phase 8, this mechanism is still more in- 

 teresting, by reason of each of the hooks called 

 chromosomes initiating a simultaneous unfolding 

 from which results a double number of hooks or 

 hemichromosomes. 



In phase 9, the single central arrangement is 

 followed by a double polar movement in which the 

 protoplasm enters into play in a radiating form 

 round each of the poles of the cell. 



In phase 10, the hemichromosomes appear grouped 

 round each pole, and as every fork is duplicated we 

 find that each pole has the same number of forks
