Every hair is a hard and elastic tube, growing 

 from an oval bulb beneath the true skin. 



The backs of the ends of our fingers and toes 

 are covered and supported by nails. These are 

 smooth, horny in their texture, and have no feel- 

 ing. They are formed from a very tender part, 

 called the root. The mode in which the skin is 

 folded under and around the nails is exceeding 

 beautiful. L: 



Nails are highly useful to us in touching and 

 grasping bodies, and in walking, as they afford & 

 firm support to the soft fleshy extremities.
