98 PROTOPLASM OF PROTOZOA 



Beams and King (1937) and King and Beams (1938) have shown 

 that the comphcated process of karyokinesis may occur in eggs of 

 Ascaris, although cytokinesis does not usually take place at very high 

 centrifugal forces. They believe that if stratification occurred, it would 

 involve a breakdown of the normal, submicroscopic spatial relations, 

 which are of importance for the maintenance of life.
