PLATE III. 



FIG. 29. A newly formed first polar spindle still within the membrane of the 

 germinal vesicle (Xi,6oo). 



FIGS. 30 and 31. Two first polar spindles in late prophases (Xi,6oo). 



FIG. 32. An equatorial plate view of the chromatin complex of a metaphase of 

 the first polar spindle (Xi,6oo). 



FIG. 33. A portion of an ovocyte showing a diagonal section through the 

 equatorial plate of a metaphase stage of a first maturation spindle. Note the 

 capsule of hyaline protoplasm surrounding the spindle, insulating it from the cyto" 

 plasm (X8oo). 



FIG. 34. An unusually fine first polar spindle in the metaphase or very early 

 anaphase. The chromosomes are all typical tetrads (Xi,6oo). 



FIG. 35. A middle anaphase of a first polar spindle, showing the diads as 

 dumbbell-shaped bodies. Faint indications of centrosomes are visible. Compare 

 the shape of the diads with that of those in the next figure ( Xi,6oo). 



FIG. 36. A late anaphase of a first polar spindle. Note the changed shape of 

 the diads, the bands-like Zwischenkorper, the insulating protoplasmic capsule 

 divided into two, and the cleavage furrow destined to cut off the polar body. The 

 position of the spindle with reference to the periphery of the ovocyte is typical 

 (Xi,6oo).
