Fig. 5. Longitudinal section through an oöcyte showing a spindle without 
asters. The chromosome pairs as arranged approximately parallel on the spindle 
attached to each other near their ends. >< 800. 
Fig. 6. Transverse section of a spindle similar to that shown in Fig. 5. 
Twelve chromosomes are present. >< 800. 
Fig. 7. Longitudinal section through an older oöcyte showing a spindle with 
the paired chromosomes crowded close together. >< 800. 
Fig. 8. Longitudinal section through an oöcyte showing a transverse section of 
a apidiils similar to that illustrated in Fig. 7. Twelfe chromosomes are present. >< 800. 
Fig. 9. Longitudinal section through an older odcyte. The spindle is here 
shorter and more compact. >< 800. 
Fig. 10. Longitudinal section through and older oöcyte. The spindle appears 
as a homogeneous mass in the shape of a cross. X 800. 
Fig. 11. Longitudinal section through an older odcyte. The chromatin of 
the spindle is shorter and broader, X 800.

stage of its history. x 800. 
Fig. 13. Section through a mass of keimbahn-chromatin which has begun 
to vacuolate. x 800. 
Fig. 14. Longitudinal section through an oöcyte containing a spindle different 
form the usual type. x 800
