cleated, and somewhat oval, with their long 

 axes at right angles to the surface. 



y. Then come several rows of cells, also granular 

 and nucleated, but becoming smaller and 

 rounder as they become more superficial. 



8. The most superficial three or four layers of 

 cells are flattened parallel to the surface, 

 are not granular, and possess no apparent 

 nucleus. 



e. Here and there a pigment-cell is seen among 

 the epidermic cells, and some of the latter 

 contain a few pigment-granules. 



The dermts, consisting fundamentally of white 

 fibrous and elastic tissues : its glandular and 

 non-glandular layers. 



t\. Immediately beneath the epidermis is a thin 

 stratum of connective tissue in which lie 

 many large pigment-cells, sometimes forming 

 an almost continuous layer. 



6. Then come a large number of round cavities, 

 the cutaneous glands, lined by large, pale, 

 slightly granular, nucleated cells, which are 

 columnar when seen sidewise, but polygonal 

 when seen from the base or apex. Some- 

 times the duct of the gland can be traced 

 running from it through the epidermis. Sepa- 

 rating the glands and supporting the epi- 

 thelium are bundles of connective tissue, 

 consisting mainly of fibres running perpen- 

 dicularly to the surface. 



i. The deepest layer of the dermis is made up
