SUMMARY.
1. The skin is the covering of the body. It has two layers, the outer, called the cuticle, and the inner, called the true skin.
2. A substance called pigment is found between the two skins. This gives the skin its color.
3. The true skin has blood-vessels and nerves, but the cuticle has no blood-vessels and very few nerves.
4. In the true skin are glands which produce sweat, and others which make fat, or oil.
5. The nails are really a part of the skin. They are firm and hard, and protect the ends of the fingers and the toes.
6. The hair grows from the true skin. The hair is made soft and glossy by oil from the oil glands of the skin.
7. The skin is a very useful organ. It removes waste matters, it breathes, it absorbs, it has feeling, and it protects the body.
