THE SKIN 



resembling the pigskin of which footballs are made. The 

 dermis is connected with the body beneath by a loose tissue 

 consisting of 

 fibers inter-

 of fat (Fig. i). 

 This tissue, to-

 surface of the 

 dermis grows 

 into numerous 

 little projections 

 called papillae 

 (Figs, i and 2).
