AliCHOPLASM DURING MITOSIS IN LARVAL SALAMANDER. 197 



Fig. 9. — Cell from the genital ridge, showing the central bodies receding 

 from one another through the mass of the archoplasm, and the intra-fibrillated 

 portion (a). 



Tig. 10.— Ditto, showing the central bodies at the extremities of the 

 pointed archoplasm. 



Fig, 11. — Ditto, Hermann's treatment and hsematoxylin. 



Fig. 12.— Recently divided cells from the genital ridge, showing interme- 

 diate body of Flemming (a), and the spindle-fibres radiating on either side 

 of this. 



Fig, 13. — Ditto, showing regenerated archoplasm on each side of the 

 division plane. Hermann's treatment and Flemming's triple stain. 



Fig. 14. — Ditto, ditto, showing central body («) entering into secondary 

 connection with regenerated archoplasm. 



Fig. 15,— Ditto. 



Fig. 16. — Two recently divided cells of the genital ridge, showing regene- 

 rated archoplasms, and relation of the central body (a). 



Figs, 17 — 19. — Leucocytes, showing archoplasm, medullary zone, and 

 central body. The latter is divided in Fig. 17, and the two portions are con- 

 nected by a dusky bridge (a). Hermann's method and hsematoxylin. 



Fig, 20. — Ditto, showing central body, radiation, and fan-shaped archo- 

 plasm. 



Fig. 21. — Cell from the embryonic genital ridge, showing the annular form 

 of the daughter-nucleus, and the relation of the central body and its radiation 

 within the annular apertures. 



Fig. 22. — Ditto, showing the interlocked condition of the archoplasmic 

 spindle and nucleus. 



Fig. 23. — Two leucocytes with attraction-spheres, after Flemming. 



Fig, 24. — Diagram showing the relation of the nuclei and the spindle.
