Parturition в предложении (на )
- The connecting link is as perceptible as the cord which binds the newly-born child to its mother; but as the umbilical cord and the placenta become after parturition useless pieces of flesh, which are carefully buried out of regard for what they once nourished, so the Church has become a useless organism, to be preserved, if at all, in some museum of curiosities out of regard for what it has once been.
- The sutures in the skulls of young mammals have been advanced as a beautiful adaptation for aiding parturition, and no doubt they facilitate, or may be indispensable for this act; but as sutures occur in the skulls of young birds and reptiles, which have only to escape from a broken egg, we may infer that this structure has arisen from the laws of growth, and has been taken advantage of in the parturition of the higher animals.
- How inexplicable are the cases of serial homologies on the ordinary view of creation! Why should the brain be enclosed in a box composed of such numerous and such extraordinarily shaped pieces of bone apparently representing vertebrae? As Owen has remarked, the benefit derived from the yielding of the separate pieces in the act of parturition by mammals, will by no means explain the same construction in the skulls of birds and reptiles.
