Those who wear these appliances of tight-lacing often complain that they cannot sit upright without them--are sometimes, indeed, compelled to wear them during all the twenty-four hours; a fact which proves to what extent such articles weaken the muscles of the trunk. The injury does not fall merely on the internal structure of the body, but also on its beauty, and on the temper and feelings with which that beauty is associated. Beauty is in reality but another name for expression of countenance, which is the index of sound health, intelligence, good feelings and peace of mind. All are aware that uneasy feelings, existing habitually in the breast, speedily exhibit their signature on the countenance, and that bitter thoughts or a bad temper spoil the human expression of its comeliness and grace. [Illustration: NATURAL HAIR.] * * * * * THE CARE OF THE HAIR. 1. THE COLOR OF THE HAIR.--The color of the hair corresponds with that of the skin--being dark or black, with a dark complexion, and red or yellow with a fair skin. When a white skin is seen in conjunction with black hair, as among the women of Syria and Barbary, the apparent exception arises from protection from the sun's rays, and opposite colors are often found among people of one prevailing feature. Thus red-haired Jews are not uncommon, though the nation in general have dark complexion and hair. 2. THE IMPERISHABLE NATURE OF HAIR.--The imperishable nature of hair arises from the combination of salt and metals in its composition. In old tombs and on mummies it has been found in a perfect state, after a lapse of over two thousand years. There are many curious accounts proving the indestructibility of the human hair. 3. TUBULAR.--In the human family the hairs are tubular, the tubes being intersected by partitions, resembling in some degree the cellular tissue of plants. Their hollowness prevents incumbrance from weight, while their power of resistance is increased by having their traverse sections rounded in form. 4. CAUTIONS.--It is ascertained that a full head of hair, beard and whiskers, are a prevention against colds and consumptions. Occasionally, however, it is found necessary to remove the hair from the head, in cases of fever or disease, to stay the inflammatory symptoms, and to relieve the brain. The head should invariably be kept cool. Close night-caps are unhealthy, and smoking-caps and coverings for the head within doors are alike detrimental to the free growth of the hair, weakening it, and causing it to fall out.
