THE HUMAN BODY. 



No blood-vessels or lymphatics enter the epidermis, which 

 is entirely nourished by matters derived from the subjacent 

 corium. Fine nerve-fibres run into it and end there 

 among the cells, in various ways. 



The Corium, Cutis Vera, or True Skin, Fig. 118, con- 

 sists fundamentally of a close feltwork of elastic and white 

 fibrous tissue, which, becoming wider meshed below, passes

gradually into the subcutaneous areolar tissue (p. 102) 

 which attaches the skin loosely to parts beneath. In 

 tanning it is the cutis vera which is turned into leather, its 

 white fibrous tissue forming an insoluble and tough com- 

 pound with the tannin of the oak-bark employed. Wherever 

 there are hairs, bundles of plain muscular tissue are found 

 in the corium; it contains also a close capillary network
