For the same reason, united to a smaller foot, and some other circumstances, women, it is observed, who execute gentle and light movements with so much skill, do not attempt with advantage great evolutions, run with difficulty and without grace, and fly--in order to be caught, as Rousseau has said. In woman, however, the muscular fibre is thus soft, yielding, feeble, and incapable of great evolutions, because it is necessary that it should easily adapt itself to remarkable changes. From all this, from women having more address in the use of their fingers, from their aptitude for little and light domestic works, the care of children, and sedentary occupations, it is evident that they cannot devote themselves to toilsome labors without struggling against their organization, and suffering proportionally. The voice being connected with the motive organs, it may here be noticed that the larynx or flute part of the throat in woman is more contracted and less prominent than in man; that the glottis does not enlarge in the same proportion; that the tongue-bone is much smaller; and that the tongue, its muscles, and the organs of speech in general, being, like all the other parts, more mobile, young girls articulate and pronounce much more quickly. Their voice is also so much more acute, that if man and woman sing in unison, there is always between them the relation of an octave, which forms the most natural and most agreeable consonance. It is evidently the UNION of all that is good in these varieties which renders beauty in the locomotive system perfect. This is perfectly represented in the Diana of Grecian sculpture, in which, with admirable taste, it is neither the nutritive nor the thinking, but the locomotive system, which is developed. * * * * * I have already said, that the temperaments of the ancients are only partial views of some of the varieties I am now describing. The _athletic temperament_ falls under the _last of these varieties_; and it is the only one that falls under this species. Happily, it does not occur in woman. This temperament results from a great development of the bones and muscles, and it is that of mere physical strength. It is marked by all the outward signs of strength: the head is small, the neck thick behind, the shoulders broad, the chest expanded, the haunches firm, the intervals of the muscles deeply marked, the tendons apparent through the skin, and all the joints not covered by muscles, seemingly small. In this temperament, muscular strength prevails over the functions of the other organs, and especially usurps the energies necessary to the production of thought; the perceptions are deficient in quickness, delicacy, accuracy, and strength; and all the mental functions are with difficulty excited; but the body is capable of great exertion, and it surmounts great physical resistance when roused.
