334 Wager. — On the Presence of Centro spheres , &c. 
Some of the striae radiating from the centrosome are in contact with the dense 
mass of chromosomes. Two small bodies (remains of nucleolus) below the group 
of chromosomes. 
Fig. 17. Longitudinal section of basidium also cut so as to show only eon 
centrosome. Threads of spindle distinctly seen. Some radiations from centro- 
some into protoplasm only. Remains of nucleolus below. 
Fig. 18. Basidium with spindle-figure and centrosomes distinct. Spindle-threads 
and centrosomes light blue in colour, very distinct ; equatorial plate of chromo- 
somes bright deep red. 
Fig. 19. Transverse section of basidium. Chromosomes beginning to separate 
into two groups. Spindle-figure and centrosomes clearly seen. 
Fig. 19 a. Same stage as above, but in longitudinal section. Centrosomes very 
distinct. Remnant of nucleolus just visible some distance below. 
Fig. 20. Later stage. Chromosomes in two groups near ends of spindle. 
Centrosomes still just visible as faintly-coloured light blue bodies. 
Fig. 21. The two groups of chromosomes just before fusing to form the two 
daughter-nuclei. The centrosomes are not visible. 
Fig. 22. Chromosomes fused to form the two daughter-nuclei. Each appears 
to be perfectly homogeneous and stained bright red. 
Fig. 23. The two daughter-nuclei just expanding. Network just beginning to 
be visible, stained bright red, and numerous deeply stained granules. 
Fig. 24. Two daughter-nuclei completely formed ; network and nucleolus 
distinctly visible ; no archoplasmic bodies visible. 
Fig. 25. Transverse section of a basidium, showing two daughter-nuclei dividing. 
Centrosomes very small. 
Fig. 26. Longitudinal section of basidium, in same stage as Fig. 25. 
Fig. 27. Four daughter-nuclei, homogeneous. 
Fig. 28. Daughter-nuclei expanding ; network begins to be visible. 
Fig. 29. Network of daughter-nuclei distinctly visible ; several deep red granules 
to be seen. At a later stage the nuclei are similar to those in Fig. 24, but slightly 
smaller.
