Thus plants very largely multiply, using this method in addition to the sexual method of egg-cells and sperm-cells. One may take "cuttings" from plants and rear them, and plants also "cut" or detach such bits themselves, in the form of runners, of dividing bulbs, of bulbules, and such reproductive growths seen on the lily, on the viviparous, alpine grass, and many other plants.
"The Finchley girl's still down with whatever it is she has, and it's something I haven't been able to diagnose yet. And I've been checking on bacteria cultures, and in what spare time I have, I've been dissecting specimens for Bill Chandler. Bill's finally found a mammal. Looks like a lizard, and it's only four inches long, but it's a real warm-blooded, gamogenetic, placental, viviparous mammal.
Taking anji or fish for my example, because it is the shortest, I may mention that he divides fish into nine "differences," two of viviparous, five of oviparous, one of crustacea, and one of scaly river fish. I will give one example of each class, merely pointing out that the letters anj occur in the middle of each name.
The first fifteen volumes of this great work, published between the years 1749 and 1767, treated of the theory of the earth, the nature of animals, and the history of man and viviparous quadrupeds; and was the joint work of Buffon and Daubenton, a physician of Buffon's native village.
"Animals, however, are sometimes oviparous." "Oviparous?" inquired Willis. "Yes, that is, they lay eggs; others are viviparous, producing their young alive. A few are multiplied like plants by cuttings, as in the case of the polypi." "Bother the polypi," said Willis, laughing, "since we have to thank them for destroying some of his Majesty's ships."
Eggs of fowls which are not fecundated, contain only the nutriment for the embryon. The embryon is produced by the male, and the nutriment by the female. Animalcula in semine. Profusion of nature's births. 2. Vegetables viviparous. Buds and bulbs have each a father but no mother. Vessels of the leaf and bud inosculate. The paternal offspring exactly resembles the parent. 3.
The anatomist may read of such recondite matters as the placenta vitellina of the smooth dog-fish, whereby the viviparous embryo is nourished within the womb, after a fashion analogous to that of mammalian embryology a phenomenon brought to light anew by Johannes Müller, and which excited him to enthusiastic admiration of Aristotle's minute and faithful anatomy.
And they also beheld many kine and many buffaloes and many old women, and many aquatic animals, many beasts of prey and many species of birds, and many specimens of viviparous and oviparous creatures, and many that are filth-born, and many belonging to the vegetable kingdom, and many animals and plants that live or grow on mountains.
The Eel, indeed, has not yet been known to lay any Spawn, but is likely to be Viviparous, as I have mention'd in the Month of January. We judge those are the best which are broad-back'd, and deep Fish; for those that are long and slender, have not their Flesh firm, which is reckon'd the Perfection of a Fish.
on the same grounds, and in the same manner and order in which a chick is engendered and developed from an egg, is the embryo of viviparous animals engendered from a pre-existing conception. Generation in both is one and identical in kind: the origin of either is from an egg, or at least something that by analogy is held to be so.
