PLATE VY. 
REGENERATION OF STRIATED MUSCLE, 
Fie. 16. Regeneration, 6 days, 6 hours. Myofibrillee (af) just beginning to 
differentiate for the flexor of the dactylopodite. >< 334. 
Fic. 17. Regeneration, 7 days, 6 hours. Showing the great elongation of 
epidermal nuclei during their invagination for the formation of the muscles,— 
in this case the flexor is the meropodite. >< 1250. (Cf. with Fig. 15.) 
Fic. 18. Regeneration, 12 days, 10 hours. Shows striation of muscle fibrils 
(mf) and their attachment to the chitin of exoskeleton. > 334. 
Ilia. 19. Showing skeletal attachment of regenerating muscle fibrils. (From 
the regenerating chela of a two-year-old lobster.) The myofibrillee appear to 
be attached directly to the chitin (ch’). x 292.
