The nervous system is a little more highly organized than in man; the heart and blood vessels adjusted to swifter work; the brain quicker; the muscles not so hard and tense. In place of the logical, she possesses the intuitive mind, which makes her capable of reaching a conclusion while man is thinking about it. She has less strength, but greater endurance; less daring in achievement, but more patience; less forcefulness, but more quiet insistence; less practicality, but more of the æsthetic; less ambition to assume the great responsibilities of life, but more painstaking in the little and no less important things which go so far towards making the days sweet and peaceful. All these differences from man, her companion, but make her the more desirable and attractive. Unlike man in her physical form, her departure from his type, was to fit her for motherhood. Narrower shouldered and less muscular, because not needing the brawn for lifting and laboring with her hands in the harder, coarser way; she is broader through the hips to give ample room for cradling her children. The pelvis is the broad flat basin, at the lower part of the body, formed by the union of the two large bones, the ossa inominata, which bound it on either side and in front, and the sacrum and coccyx which complete it behind. The sacrum and coccyx are the nine lower vertebræ of the spinal column, five in the sacrum and four in the coccyx. All the bones in the pelvis in woman are lighter and more delicate than in man—in whom they are designed mainly for strength—and the protuberances for the attachment of muscles are less prominent, making a smoother inner surface in the pelvis of woman. Neither are the joints so inflexible as in man; that of the coccyx with the sacrum being quite movable, while the union of the two bones in front will permit slight separation during the act of childbirth. Within this pelvis lie the internal generative organs, namely, the uterus, or womb, the ovaries and fallopian tubes, and beside these the rectum and bladder. The pelvis belongs to these organs and to these alone; but how often their sphere is trespassed upon by the crowding down of the organs above, is matter for grave consideration. To each of these organs is given space sufficient, if their room be not infringed upon by each other or by the abdominal viscera above.
