Fig. 8. — A lamprocjte stained with gentian violet. (Camera. X 700.) 

 Tlie vacuoles and granules are represented ot their real size. The nucleus is 

 shown and the creasing of the cell-membrane. 



Fig. 9.— a typical linocjte, from discharged fluid, slightly compressed and 

 dead, showing nucleus and complex "thread-coil." 



Tig. 10. — A young linocyte, showing the honeycomb appearance of the 

 cytoplasm, and the great central vacuole and peripheral nucleus. 



Fig. 11. — A slightly older linocyte, with enlarged vacuole; Hie honeycomb 

 appearance of the cyto))lasm no longer exists. 



Figs. 12 — 15. — Sketches of four linocytes in different stages of develop- 

 ment, showing the method of origin of the "thread" within the vacuole. 

 These sketches are slightly diagrammatic, but represent faithfully the ap- 

 pearance of the ihread. 



Fig. 16. — A young linocyte in which several large vacuoles exist, in each 

 of which a thread-coil will arise (fresh). 



Fig. 17. — A linocyte with several independent rings or thread-coils. 



Figs 18 — 20.-^Living linocytes with more tlian one thread-coil, to illus- 

 trate the variety of form assumed by this cell product. The details of the 

 cytoplasm are not fully represented. 



Fig. 21. — A linocyte with a single thread-coil and three large vacuoles, in 

 which probably threads will appear later on. 



Fig. 22. — A linocyte (dead) containing two thread-coils, one of which has 

 an exceptional form, wiiicli is further indicated at a ; n is the nucleus. 



Fig. 23. — A linocyte after the addition of nitric acid to the preparation. 

 The thread is indistinct, but a series of radiating lines occupy the peripheral 

 region of the cell, which are possibly paits of tlie disentangled thread. 



Fig. 21. — A linocyte after further action of nitric acid ; the cell membrane 

 has become ruptured, and the unravelling thread is issuing in the form of 

 loops. 



Fig. 25. — The thread-coil after potash has dissolved the cytoplasm. As the 

 reagent acts the thread undergoes the changes represented at a, b, c, the 

 thread-coil or ring swells up, and the fibrils separate from one another. 



F'iG. 26.— Three sketches of threads left after the action of boiling potash, 

 to illustrate the continuity of the thread.
