into a dense plexus of fine nerve-fibres in the super- 

 ficial layer of the coriuin. This plexus extends hori- 

 zontally, and gives off numerous elementary fibrils 

 to the stratum Malpighii, in which they ascend verti- 

 cally and in a more or less wavy fashion towards the 

 stratum lucidum (Langerhans, Podkopaeff, Eberth, 

 Eimer, Ranvier, and others). According to some, they 

 terminate with a minute swelling ; according to others, 

 they form networks ; but they always remain between 

 the epithelial cells. 



The subcutaneous nerve-branches of some places 

 palm of hand and foot and skin of penis give 

 off' single medullated nerve-fibres, terminating in a 

 Pacinian corpuscle, mentioned in a former chapter. 

 In the volar side of the fingers and toes there occur 

 iu some of the papillae of the coriuin the tactile or 

 Meissner's corpuscles, each connected with one or two 

 medullated nerve-fibres, as described in a previous 

 chapter. The outer root-sheath of the hair-follicles 

 contains the terminations of fine nerve-fibres, in the 

 shape of primitive fibrillse (Jobert, Bonnet, and 

 Arnstein). According to Jobert, the nerve-fibres 

 entwine the hair-follicle in circular turns. The tactile 

 hairs possess a greater supply of nerves than the 

 ordinary hair-follicles.
