So widely did the ancients disagree with us in respect of beauty, that, with them, a small forehead, and eye-brows joined, were accounted ornaments in the female countenance; and even to this day, in Persia, the union of the eye-brows is held in high estimation. In several parts of the Indies, it is necessary that the teeth should be black, and the hair white, to form a beauty; and, in the Marian islands, it is a principal occupation of the women, to blacken the teeth with herbs, and to whiten the hair by certain lotions. In China and Japan, the essential ingredients of beauty are, a large visage, small eyes, and almost concealed, a nose flat and bulky, little feet, and a belly enormously big. Some of the Indians of America and Asia, in order to enlarge the countenance, compress the heads of their children between two planks, others flatten them from the crown only, and others exert every effort to render them round. Every nation, and every individual, has a peculiar prejudice, or taste, with respect to beauty, which probably originates from some pleasing impression received in infancy, and therefore depends more, perhaps, on habit and chance than on the disposition of our organs.

When we come to treat of the different senses, we shall perhaps be able to determine what stress is to be laid on the ideas of beauty which we receive from the eyes. In the mean time let us examine the human countenance as it appears when agitated by the passions. In grief, joy, love, shame, and compassion, the eyes swell, and overflow with tears. The effusion of these is always accompanied with a tension of the muscles of the face, which opens the month. The natural moisture in the nose becomes increased by the tears flowing through the lachrymal ducts; they do not, however, flow uniformly, but burst out by intervals.

In sorrow the corners of the mouth are lowered, the under lip raised, the eye-lids nearly closed, the pupil elevated, and almost covered with the eye-lid; the other muscles of the face are relaxed, so that the space between the mouth and the eyes is larger than ordinary, and of consequence the countenance appears lengthened. [See _fig._ 13.]

In fear, terror, or horror, the forehead is wrinkled, the eye-brow raised, the eye-lids are extended as much as possible, and discover a part of the white over the pupil, which is lowered, and somewhat concealed by the lower eye-lid: the mouth, at the same time, is widely opened, and the lips separating, both the upper and under teeth are seen.
