Plate XI 



Figs. 56-59 Taken from sections of regenerating eye shown in Fig. 36. Fig. 56 from section near 

 dorsal surface. Regenerated tissue lies for the most part peripheral to the broken line x-y. Cuticle 

 torn and inner tissues shrunken from it. Old tissues show parts of muscle bands and small groups of 

 ganglion cells. Distal to muscle band new tissue seems differentiated into fibers. X 90. 



Fig. 57 Shows section deeper below surface than Fig. 35. Same features as in preceding figure. 

 In addition a few small pigment masses. An increase in size of the nuclei in region from h to c. Cuticle 

 not shown. X 90. 



Fig. 58 Represents upper part of tangental section near the ventral surface. Nuclei increased in 

 size and number over those in preceding figure. Rudimentary ommatidial elements apparent in new 

 tissue. Figure composed entirely of regenerated tissue except small group of ganglion cells. X 90. 



Fig. 59 Rudimentary ommatidia from the eye shown in Fig. 36. Sections oblique so that entire 

 ommatidium cannot be recognized. Shows distal ends of cones, retinular nuclei and pigmented proc- 

 esses which appear to be retinulae. X 900.
