DESCRIPTION OF PLATE XL 



Illustrating Mr, Rainey's paper on the Structure of the 

 Cutaneous Follicles of the Toad. 



Fig. 



1. — Skin of toad injected, showing cutaneous capillaries. 



2. — Opposite side of the same piece of skin, showing one of the cutaneous 

 follicles. 



3. — A vertical section of the skin, showing some follicles cut perpendi- 

 cular to the surface. 



a. One cut at its middle, where it communicates with the 



surface. 



b. b. Follicles cut on one side of their centre. 



c. A layer of earthy matter lying over the follicle, between it 



and the surface. 

 These three are magnified 20 diameters. 



4. — Horizontal section of a follicle, showing the folds of internal mem- 

 brane. 



a. The layer of capillaries. 

 h. Internal membrane. 



c. Epithehum covering the follicles of the internal membrane. 

 Magnified 50 diameters. 



5. — A. Deep portion of the epidermis, showing the form of the epidermic 

 scales, and the clear, homogeneous nuclei. 

 P>. Epithelium of a cutaneous follicle, showing the character of the 

 epithelic cells and the granular nuclei, with some of the 

 granular contents of the follicle. 



Magnified 300 diameters.
