The hollow or concave side of the kidneys is turned inwards, and the deep fissure of this side, known as the hilus, widens out to form the pelvis. Through the hilus the renal artery passes into each kidney, and from each hilus passes outwards the renal vein, a branch of the inferior vena cava.

The dictum of the founder of modern pathology, Virchow, that Woman was in effect an appendix to the ovaries, has long been taken to apply to her psychic traits as well as somatic. Her mind, like her skin, her hair and her pelvis, is a product of the ovarian endocrines. But these determinations are by no means her monopoly.
Hard parts seem to affect the form of adjoining soft parts; it is believed by some authors that the diversity in the shape of the pelvis in birds causes the remarkable diversity in the shape of their kidneys. Others believe that the shape of the pelvis in the human mother influences by pressure the shape of the head of the child.
It was remarkable that when the pessary was removed it was found to have largely retained its original wax covering. Hurxthal mentions the removal of a pessary which had been in the pelvis for forty-one years. Jackson speaks of a glove-pessary remaining in the vagina thirty-five years. Mackey reports the removal of a glass pessary after fifty-five years' incarceration.
I could just feel one of the hind legs. No time was to be lost. I introduced a small pair of forceps by the side of my finger, and succeeded in laying hold of the leg without much difficulty, and, with two or three weak efforts from the mother, I could scarcely call them pains, I brought the leg down until it was in the cavity of the pelvis.
Later, when his pelvis was raised to allow the introduction of a bed-pan, almost instantaneous death ensued. Upon postmortem examination prolonged and careful search failed to reveal any microscopic change in the brain, its vessels, or the meninges.
The heads of the thigh bones not only actually, in consequence of growth, but also relatively, in consequence of change of shape in the pelvis, become more widely separated from each other than they are in childhood, and hence the gait and the manner of running alters greatly in the adult woman.
The irregular bones of the pelvis, unnamed on account of their non-resemblance to any known object. Minute crystals of lime in the vestibule of the ear; also known as otoliths. The roof of the mouth, consisting of the hard and soft palate. A violent and irregular beating of the heart. Papilla. The small elevations found on the skin and mucous membranes.
The Sirenia form a very distinct group of the mammals, and one of the most remarkable peculiarities in existing dugong and lamentin is the entire absence of hind limbs, without even a rudiment being left; but the extinct Halitherium had, according to Professor Flower, an ossified thigh-bone "articulated to a well-defined acetabulum in the pelvis," and it thus makes some approach to ordinary hoofed quadrupeds, to which the Sirenia are in other respects allied.
