PLATE LXII (continued)
Fig. 8.—Spermatocyte of Proteus (Hermann), ii, Nucleus in the spirem or thread stage ; ti, attraction -sphere with rod-shaped
bodies and single centrosome. Figs. 5, 6, 7, and 8 illustrate concentric, radiating, and reticular arrangements.
Fig. 9.—Nucleus from crypt of Lieberkiihn in Salamander (Heidenhain). Contains three plasmosomes or true nucleoli (n'); also
chromatin net-work (c) with some fine linin-threads (a).
Fig. 10.—Remarkable permanent spirem-nucleus from salivary gland of larva of chirononius ; chromatin arranged in a single
thread with chromatin discs terminating at either end in a true nucleolus or plasmosome (Balbiani). Shows spiral arrangement of a
kind.
Fig. 11.—Section of nephridian cell of leech (Clepsine) as drawn by Arnold Gray, n, Nucleus invested with chromatin membrane,
containing granules and a single nucleolus with vacuoli (v) ; v', v', large vacuole in centre of cell filled with watery fluid ; c, reticulum
formed by cytoplasm and containing centrosomes, well marked on peripheral zone.
Fig. 12.—Spinal ganglion-cell of frog (Lenhossek). n, Nucleus with intensely chromatic nucleolus (n') and pale linin-network
with chromatin rounded granules (c) ;
