Woman’s figure is ordinarily characterized by a relative gracility, the forms are more delicate, the contours more rounded, and the waist narrower than in man. The skeleton is more delicate, the stature lower. The head is smaller and covered with more hair. The hairs are luxuriant. The features of the face are more delicately cut, the beard is wanting, the eyes are more beautiful and lustrous, the cheeks are rounder, and the lips daintily curved. The neck is round and long, lacking the laryngeal projection. The chest is narrower, the shoulders sloping. The hemispheric form of the breasts with the well-pronounced mammilae render the bosom highly attractive. The abdomen is longer, hence the distance between the navel and the pubes is greater than in men. The pelvis is lower and larger than in the male, and surpasses the line of the shoulders. The inclination of the pelvis is more pronounced, hence the buttocks are more protuberant. The woman’s body thus seems to be somewhat more reminiscent of the quadrupedal posture than man’s. There is a greater obliquity and conicity of the thighs. The calves are very pronounced. The skin, in general, is of a finer texture, whiter, smoother and less hairy than in men. The paniculus adiposus is abundant, hence the figure is all curves and does not show the angles, as in man. The limbs are relatively short, more delicate, more rounded, tapering and less muscular than in man. The feet are smaller and more daintily shaped. The hands are comely and the fingers slender. The woman’s steps are shorter, her gait more graceful. The woman’s voice differs in pitch as well as in timbre from man’s. It has a higher note and sweeter tone. The woman’s respiration is of the upper costal type. PART IV. PHYSIOLOGY OF SEX CHAPTER VI CELL-DIVISION, MATURITION, IMPREGNATION [Illustration: CUT XXVII. _Fissiparous reproduction of the amoeba._ The single-celled animal “a” is divided after different steps into two animals, “f” and “g.”] The main function of the genital glands is the production of germ-cells, the spermatozoa in the male and the ova in the female. This production is effected by means of cell-division. The division may be direct as found in the fissiparous reproduction of the amoeba. As soon as the cell reaches a certain size, it divides itself into two cells. The more complicated form of cell-division is the indirect division called “Mitosis” or “Karyokynesis.” As shown before the cell consists of two main parts, the smaller part called the nucleus and the larger portion called the cytoplasm. The nucleus shows in its interior a linin net and deeply staining granules. Because of this quality they are called “chromatin.” The cytoplasm in the close proximity of the nucleus contains minute granules, situated either singly or in pairs which are called “centrosomes.”
