THE SKIN OUR WONDERFUL COAT What the Skin Is.

The skin is the most wonderful and one of the most important structures in the body.

We are prone to think lightly of it because it lies on the surface, and to speak of it as a mere coating, or covering--a sort of body husk; but it is very much more than this.

Not only is it waterproof against wet, a fur overcoat against cold, and a water jacket against heat, all in one, but it is also a very important member of the "look-out department," being the principal organ of one of our senses, that of touch.
The eyes in the beginning were simply little colored patches of the skin, sunk into the head for the purpose of specializing on the light-rays.

The smelling areas of the nose also were pieces of the skin, as were also the ears.
