the peculiar position and nature of the organs con­tained in the pelvis ; but to call attention to the peculiar structure of the knee, and the shallowness of the pelvis, and the delicate nature of the foot as part of a sustaining column.- The knee-joint of wo­man is a sexual characteristic. Viewed in front and extended, the joint in but a slight degree interrupts the gradual taper of the thigh into the leg. Viewed in a semiflexed position, the joint forms a smooth ovate spheroid. The reason of this lies in the small­ness of the patella in front, and the narrowness of the articular surfaces of the tibia, and femur, and which in man form the lateral prominences, and thus is much more perfect as part of a sustaining column than that of woman. The muscles which keep the body fixed upon the thighs in the erect position labor under the disadvantage of shortness of purchase, owing to the short distance, compared to that of man, between the crest of the ilium and the great trochanter of the femur, thus giving to man a much larger pur­chase in the leverage existing between the trunk and the extremities. Comparatively the foot is less able to sustain weight than that of man, owing to its shortness, and the more delicate structure of the tarsus and metatarsus. I do not think there can be any doubt that women have instinctively avoided some of the skilled labors on anatomical peculiarities.
