 Guenther). 



(c) Linin, closely applied to the chromatin, does 

 not stain ; dissolves in distilled water ; 



(d) Nuclear sap, a fluid perhaps analogous to the 

 hyaloplasm ; 



(e) Nucleolus, spherical body that stains heavily; 

 (/) Nuclear net knots, or karyosomes, false nuclei 



that are nodal points formed by interlacing chro- 

 matin network; 



(g) Nuclear membrane, amphipyrennin ; 



(h) Centrosome, a small spherical body often found 

 in the cytoplasm near the nucleus. It is looked upon 

 as the dynamic center in cell division. 



Mitosis or Karyokinesis. Mitosis is indirect cell
