Mountain breeds always differ from lowland breeds; and a mountainous country would probably affect the hind limbs from exercising them more, and possibly even the form of the pelvis; and then by the law of homologous variation, the front limbs and even the head would probably be affected. The shape, also, of the pelvis might affect by pressure the shape of the head of the young in the womb.
"These young doctors have taken this out of me, and that out of me, as you might take the works out of a watch. And it has done no good; and they were mistaken in their first diagnoses, because what they took for true osteomalacia was only Would you mind telling me again? Oh, yes; I had only a pseudo-osteomalacic rhachitic pelvis, to begin with.
In the superior portion of the limb the muscles are heavy, tapering inferiorly, and terminating in the region of the foot in long tendons. Each limb is divided into four regions. The regions of the fore-limb are the shoulder, arm, forearm and forefoot. In the hind limb are the regions of the pelvis, haunch, thigh, leg and hind-foot. The feet in turn are divided into three sub-regions each.
He made precise observations and came to the conclusion that owing to erectile properties in the neck of the uterus, this part of the womb elongates during congress and reaches down into the pelvis with an aspiratory movement, as if to meet the glans of the male.
But it is in the structure of the pelvis and of the hind limb that some of these ancient reptiles present the most remarkable approximation to birds, and clearly indicate the way by which the most specialised and characteristic features of the bird may have been evolved from the corresponding parts of the reptile.
With the occurrence of suppuration the disease becomes more active, and abscesses may form in the soft parts and in the adjacent joint. In the vertebral column, hydatids give rise to angular deformity and paraplegia. In the pelvis, there is usually great enlargement of the bones, and when suppuration occurs it is apt to infect the hip-joint and to terminate fatally.
It would appear impossible that in any species there should exist a well-developed uterus containing a full-sized foetus, and yet that the arch of the pelvis should be too small to allow the foetus to pass.
This is proved by the fact that in those rare cases in which the internal organs of generation are absent, or fail to develop, there is a corresponding failure in the pelvis to alter into the normal adult shape. The muscles of the growing girl partake in the rapid growth and development of her bony framework.
Protruding jaws and chin, even when combined with large cranium and brain, always give man the appearance of brutality and low intelligence. The pelvis is broad and comparatively shallow. The legs, especially the thighs, are long. The foot is long and strong, and rests its lower surface, not merely the outer margin as in apes, on the ground.
Regarded systematically, the cerebral differences of man and apes are not of more than generic value; his Family distinction resting chiefly on his dentition, his pelvis, and his lower limbs.
