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

 ficial layer of the corium. 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 

 m some of the papillae of the corium 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.
