Not only so, but--although it is a little hard for you to understand how this could have happened--the whole brain and nervous system is made up of folds of the skin tucked in from the surface of the back; so that we can say that the skin, with the organs that belong to it and have grown from it--the eyes, nose, ears, brain, and nerves--forms the most wonderful part of the body.

Everything that we know of the world outside of us is told us by the skin and the look-out organs that have grown out of it.

The skin is not only the surface part and coating of the body, far superior to any six different kinds of clothing which have yet been invented, but it is related to, and assists in, the work of nearly half the organs in the body.

Not only all that we learn by touch and pressure, but everything that we know of heat and cold, of moisture and dryness, and most of pain, comes to us through our skin, through the little bulbs on the ends of the nerve twigs in it.

It also helps the lungs to breathe, the kidneys to purify the blood, and the heart to control the flow of blood through the body.
A healthy skin is of very great importance; and part of this health we can secure directly, by washing and bathing, scrubbing and kneading and rubbing, because the skin lies right on the surface, where we can readily get at it.
