Seite 325 - Entire trunks of trees, which are carried by the rivers from other countries and islands, find here, at length, a resting-place, after their long wanderings ; with these come some small animals, such as lizards and insects, as the first inhabitants. Even before the trees form a wood, the...
Seite 87 - I have elsewhere shown, if the viscera of an animal are so organized as only to be fitted for the digestion of recent flesh, it is also requisite that the jaws should be so constructed as to fit them for devouring prey; the claws must be constructed for seizing and tearing it to pieces; the teeth for cutting and dividing...
Seite 324 - Island is well advanced in the above progressive state ; having been many years, probably some ages, above the reach of the highest spring tides, or the wash of the surf in the heaviest gales. I distinguished, however, in the rock which forms its basis, the sand, coral, and shells formerly thrown up, in a more or less perfect state of cohesion ; small pieces of wood, pumice stone, and other extraneous bodies which chance had mixed with the calcareous...
Seite 91 - ... a claw, a shoulder-blade, a condyle, a leg or arm bone, or any other bone separately considered, enables us to discover the description of teeth to which they have belonged ; and so also reciprocally we may determine the forms of the other bones from the teeth. Thus commencing our investigations by a careful survey of any one bone by itself, a person who is sufficiently master of the laws of organic structure may, as it were, reconstruct the whole animal to which that bone belonged.
Seite 314 - ... parts where it rises, a barrier against the invasion of these sands, the shores of the river, on that side, would long since have ceased to be habitable. Nothing can be more melancholy...
Seite 7 - A nice and scrupulous comparison of their forms, of their contexture, and frequently even of their composition, cannot detect the slightest difference between these shells and the shells which still inhabit the sea. They have therefore once lived in the sea, and been deposited by it : the sea consequently must have rested in the places where the deposition has taken place.
Seite 118 - Cuvier, the relation of the bones with each other remain essentially the same; the form of the teeth never changes in any perceptible degree, except that in some individuals, one additional false grinder occasionally appears, sometimes on the one side, and sometimes on the other •f-.
Seite 107 - ... in the fissures and caverns of certain rocks, or at small depths below the present surface, in places where they may have been overwhelmed by debris, or even buried by man. Human bones are never found except among those of animal species now living, and in situations which show, that they have been, comparatively speaking, recently deposited.
Seite 86 - Every organized individual forms an entire system of its own, all the parts of which naturally correspond, and concur to produce a certain, definite purpose, by reciprocal reaction, or by combining towards the same end.
Seite 16 - ... that their summits have never again been covered by the sea since they were raised up out of its bosom. Such are those primitive or primordial mountains which traverse our continents in various directions, rising above the clouds, separating the basins of the rivers from one another, serving by means of their eternal snows as reservoirs for feeding the springs, and forming in some measure the skeleton, or as it were the rough framework of the earth.
