 wards reduced to ^^o diameter by photography. The following letters apply 

 to aU : — e, epidermis ; d, dermis ; m, medullated nerve ; n, non-meduUated 

 nerve ; c, nerve-ganglion cell ; /, forked terminations of (tactile) nerves ; /;, hair 

 or bair-follicle; ?'/, intraepidermic nerve-fibrUs ; o c, nerve-fibrils of outer circle ; 

 i c, nerve-fibrils of inner circle ; cf, central nerve-fibrils ; /, nerve-coil of Jobert ;

 figure, or in the text. 



Plate XIII. 

 Fig. 1. Perpendicular section through the skin of the nose of the Mole, showing 



the arraiigemeut of terminal nerve-fibrils called the organ of Eimer. 



a, epidermic dowugrowth ; j;. Pacinian body. j^j,. (See p. 567.) 

 Fig. 2. Transverse section across organ of Eimer in the Mole. 

 Fig. 3. Forked nerve-terminations on the dermic sm'face of the epidermic lining 



of a hair-follicle on the tail of a Mole. The drawing shows only one 



fourth of the circumference of the hair-follicle. (See p. 562.) 

 Figs. 4 and 5 are examples of developing nerve-terminal apparatus from a 



large and a small hair on the nose of a newly-born kitten. (See p. 563.) 

 Fig. 6, Examples of nerve-terminal apparatus on large and small hair-follicles 



from the tail of a Water-Shrew, s, sebaceous gland. (See also PI. XIV. 



fig. 15.)
