PLATE 2 
EXPLANATION OF FIGURES 
~ 
7 Section of a granular gland, showing mitosis in secreting cells at the bottom 
of the alveolus. Kleinenberg; Ehrlich’s haematoxylin and eosin. X 178. 
8 Surface view of the cuticular margin, showing the polygonal areas (ends of 
alveoli). Drawn from an unstained preparation of the cuticular layer. X 733. 
9 Tangential section of a granular gland in which the muscular layer is not 
yet developed, showing a giant nucleus. X 178. 
10 Section similar to that represented in figure 9, showing a multinuclear 
condition in some granular cells and the grouping of nuclei in twos and fours in 
other parts where the cell walls have disintegrated. Kleinenberg; Ehrlich’s 
haematoxylin and eosin. X 178. 
11 Epidermis from the toe, showing the horny layer and the cell processes of 
the germinative layer which extend into the dermis. Kleinenberg; Ehrlich’s 
haematoxylin and eosin. X 178. 
12 Section of integument, perpendicular to the surface, from the dorsal side 
of the head, showing epidermis, three layers of dermis, subcutaneous connective 
tissue, pigment and a mature mucous gland in median longitudinal section. 
Somewhat diagrammatic. Kleinenberg; Ehrlich’s haematoxylin andeosin. X 73. 
13. Median longitudinal section of a developing granular gland, showing a 
cluster of cells in the region of the connection with the epidermis. Intercalary 
cells present. Cell walls gone in the upper portion of the gland sac. At the 
bottom are two flattened cells just external to the definitely arranged epithelium.
