To understand the present variety, the bony structure on which it especially depends, must now be more minutely described. Commencing with the trunk of the body--the chest in woman is shorter but more expanded; the breast-bone is shorter but wider; the two upper ribs are flatter; the collar-bones are more straight or less curved, and do not present that prominent relief which appears on the chest of man; the shoulders are carried farther back, and project less from the trunk. The haunches, as already stated, are proportionally wider in woman than in man, and the interior cavity of the pelvis, which is between them, being adapted to gestation, is more capacious. This greater capacity of the pelvis arises from the lateral parts having in woman more convexity outward; from the bones called ossa pubis, which form the anterior part, touching at a smaller number of points, and running obliquely or forming a greater angle, to enlarge the space which is between them and the inferior extremity of the posterior part of the pelvis; from the arch of the pubis being larger; from the greater concavity and breadth of the os sacrum or posterior bone of the pelvis, its posterior part forming a greater prominence outward; and from the whole pelvis being thus wider and less deep, its circumference approaching more to the circular form. The cavities, it may be added, in which the heads of the thigh-bones are received, are of course farther apart: they are also oblique and less deep. The arms of woman are shorter than in man.--As these members are well marked in beauty of the locomotive system, they may the more fully be considered here.--The arms, and especially their extremities, are susceptible of a degree of beauty of which we see few examples. Their bases, the bones, ligaments, and muscles, belong to the locomotive system; and their fundamental beauty consequently depends upon its proportions; but to the nutritive system are owing the circumstances that, in woman, the arm is fatter and more rounded, has softer forms and more flowing and purer outlines. The hand in woman is smaller, more plump, more soft, and more white. It is peculiarly beautiful when full; when it is gently dimpled over the first joints; when the fingers are long, round, tapering toward the ends; when the other joints are marked by slight reliefs and shadows; and when the fingers are delicate and flexible. Beauty of the hand becomes the more precious, because it is the principal organ of a sense which may be considered as the most valuable of all.
