subcutaneous tissue and in the deeper part of the corium; ftieir ducts 

 extend through the corium to the under surface of the epidermis where 

 the lining epithelium of the duct becomes continuous with the cells of 

 the interpapillary portion of the stratum germinativum. In its further 

 course through the epidermis the duct of the gland forms only a

tortuous spiral cleft or passage whose wall is formed only by the con- 

 centrically placed cells of the various epidermal layers through which 

 it passes. The glands of the axilla and circumanal region are branched. 

 The secreting or coiled portion of the gland (fundus) consists of a 

 secretory epithelium resting upon a delicate hyaline membrana propria 

 in whose outer portion are concentrically disposed connective tissue 

 fibers. The inner portion of this membrane contains many longitudinal
