Mammalia   Listen
noun
Mammalia  n. pl.  (Zool.) The highest class of Vertebrata. The young are nourished for a time by milk, or an analogous fluid, secreted by the mammary glands of the mother. Note: Mammalia are divided into three subclasses; I. Placentalia. This subclass embraces all the higher orders, including man. In these the fetus is attached to the uterus by a placenta. II. Marsupialia. In these no placenta is formed, and the young, which are born at an early state of development, are carried for a time attached to the teats, and usually protected by a marsupial pouch. The opossum, kangaroo, wombat, and koala are examples. III. Monotremata. In this group, which includes the genera Echidna and Ornithorhynchus, the female lays large eggs resembling those of a bird or lizard, and the young, which are hatched like those of birds, are nourished by a watery secretion from the imperfectly developed mammae.

"Mammalia" Quotes from Famous Books



... &c.—have no outward appendages, they are destitute of ears and the power of hearing. But you must wait till you are a little older, and then I will explain to you the matter more fully. The little curiously shaped earbones which are found in all mammalia are found also in the mole; and I have in my drawer at home a mole's earbones which I dissected ...

... intensity of the main phenomenon (as marked by its principal characters, Sensation, Thought, Voluntary Motion, etc.) begins to be attended by conspicuous changes in the miscellaneous properties of the animal. Such well-marked changes take place, for example, where the class Mammalia ends; at the points where Fishes are separated from Insects, Insects from Mollusca, etc. When so formed, the primary natural groups will compose the series by mere juxtaposition, without redistribution; each of them corresponding to a definite portion of the scale. In ...

It is only 1/25000 of an inch long, and, expressed in tenths of a micron, the average ...

... much nearer than to any other animal, is a well known fact, disputed by nobody. Looking at the matter from the point of view of organisation alone, no one probably would ever have disputed the view of Linnaeus, that man should be placed, merely as a peculiar species, at the head of the mammalia and of those apes. Both shew, in all their organs, so close an affinity, that the most exact anatomical investigation is needed in order to demonstrate those differences which really exist. So it is with the brains. The ...

... Radiates,—Polyps, Acalephs, and Echinoderms; three classes of Mollusks,—Acephala, Gasteropoda, and Cephalopoda; three classes of Articulates,—Worms, Crustacea, and Insects; and, according to the usually accepted classification, four classes of Vertebrates,—Fishes, Reptiles, Birds, and Mammalia. If there is indeed a transition between all these classes, it must become clear to us, when we have accurately interpreted their relative standing. Taking first the lowest branch, how do the classes stand within the limits of the type of Radiates? I ...

The Pliocene, on the other hand, is of freshwater origin, and contains silicified wood and numerous remains of Mammalia. Flint chips, which appear to have been fashioned by hand, are said to have been found in the Miocene beds, but to prove the existence of man at so early a period would require stronger evidence than has yet been ...

... generalize on such a subject; nor should we expect to find it an easy task, when we remember the vast number of species (about a quarter of a million) already noticed by naturalists. Linnaeus succeeded, however, in finding a common character on which to unite most of his classes; but the Mammalia, that group to which we ourselves belong, remained very imperfect. Indeed, in the earlier editions of his classification, he does not apply the name of Mammalia to this class, but calls the higher animals Quadrupedia, characterizing them as the animals with four legs ...

... mermaid, with the body of a woman and the scaly tail of a fish, I should at once say that I could not believe him. And why? because it is contrary to the laws of nature. The two component parts of the animal could not be combined, as the upper portion would belong to the mammalia, and be a hot-blooded animal, the lower to a cold-blooded class of natural history. Such a junction would, therefore, be impossible. But there are, I have no doubt, many animals still undiscovered, or rather ...

Anakim said there was no call for any new invention in that line so long as Halicarnassus continued in his present appetite,—with a significant glance at the plump chicken which the latter was vigorously converting into mammalia, and which probably was the very one that disturbed the Anakim's repose. And then we discussed the day's plan of operations. Halicarnassus said he had been diplomatizing for a carriage. The man in the office told him he could have one for five dollars. He thought that was rather high. Man ...

Mr. Wallace goes on to answer the objection of Professor Boyd Dawkins, "that man did not probably exist in Pliocene times, because almost all the known mammalia of that epoch are distinct species from those now living on the earth, and that the same changes of the environment which led to the modification of other mammalian species would also have led to ...

On the other hand, it is said that the Mollusca and Radiata of the very earliest periods were more highly organized than the great ...
