SUDORIFEROUS DUCTS. -529 



parous gland are lined by an inflection of the epidermis. This inflec- 

 tion is thick and infundibiliform in the upper stratum of the dennis, 

 but soon becomes uniform and soft. The infundibiliform projection is 

 drawn out from the duct when the epidermis is removed, and may be 

 perceived on the under surface of the latter as a nipple-shaped cone. A 

 good view of the sudoriferous ducts is obtained by gently separating 

 the epidermis of a portion of decomposing skin ; or they may be 

 better seen by scalding a piece of skin, and then withdrawing the epider- 

 mis from the dermis. In both cases it is the lining sheath of epidermis 

 which is drawn out from the duct.
