Some Observations on the Chromosome Vesicles in the Maturation etc. 105 
Figs. 2, 3. Early prophase of first maturation. A large part of the germi- 
native vesiele still intact. Chromosomes forming as isolated bodies 
in the meshwork of linin. 1/12,4. 
Fig. 4. Prophase first maturation. Germinative vesicle completely absorbed. 
Chromosomes rod-shaped and forming in the equatorial region of the 
spindle. 1/12,4. 
Fig. 5. Metaphase of first maturation spindle. Chromosomes rod-shaped and 
of irregular outline.e Centrosome differentiated into centriole and 
centroplasm. 1/12,2. 
Fig. 6. Anaphase first maturation spindle. 1/12,2. 
Fig. 7. Anaphase first maturation spindle showing the division of the cen- 
trioles. 1/12,4. 
Fig. 8. Anaphase first maturation spindle. Centrioles in deep centrosome are 
united by fibres. Prophase stage in the division of the first polar cell. 
1/12,4. 
Figs. 9—10. Prophase second maturation spindle. Chromosomes enclosed in 
chromosome vesicles. The indireet or longer process in the formation 
of the second polar cell. 1/12,2. 
Fig. 11. Prophase second maturation spindle, sborter or direet process. 1/12,2. 
Figs. 12—13. Prophase stages in the formation of the second maturation 
spindle by the indireet process. Chromosomes in the form of chro- 
matin granules enclosed in chromosome vesicles. 1/12,2. 
Fig. 14. Metaphase in second maturation spindle. Polar cell in same stage. 
1/12,4. 
Figs. 15—22. Telophase second maturation. The egg-chromosomes lie either 
in a single vesiele or in several. The chromosomes of the polar cell 
are found in a single vesiele or several. Figs. 15—20, 1/12,2; Figs. 21, 
22, 1/12,4. 
Fig. 23. The prophase stage of the first maturation showing a large cell-like 
body in the process of formation. 1/12,2. ,
