FIG. 44. Early mitosis in a lymphocyte. Looking down through the 

 spindle (polar aspect). The nucleolus has divided into two centrosomes, 

 each of which is ring-shaped. The spindle is surrounded by a belt of chro- 

 matin granules. 



FIG. 45. Mitosis in a lymphocyte. Profile aspect. The two ring- 

 shaped centrosomes can just be seen towards the poles. The granules are 

 becoming formed into chromosomes.
