On the other hand, existing reptiles have no feathers. They may have naked skins, or be covered with horny scales, or bony plates, or with both. They possess no wings; they neither fly by means of their fore-limbs, nor habitually walk upright upon their hind-limbs; and the bones of their legs present no such modifications as we find in birds.
But if flight was absolutely necessary, she sped away towards the nearest gap, and thence over pasture and cornfield, always up-hill if possible, out-distancing any probable pursuer by the marvellous power of her long hind-limbs. During the late summer and the early autumn, nothing occurred to endanger the leveret's life. The corn grew tall and slowly ripened.
The Sirenia, so called by reason of their fanciful resemblance to the sirens of mythology, among which are the sea-cows, manatees, dugongs, etc., which are fish-like in structure and appearance, the fore-limbs being shaped like paddles, or fins, and the hind-limbs being absent or rudimentary;
In the vertebral column and the hind-limbs there are no special resemblances to birds, and when we turn to the wings they are found to be constructed on a totally different principle from those of birds. There are four fingers.
It is usually about seven feet in length, and five round the thickest part of the body, which latter is quite smooth, and tapers off into a horizontal flat tail, semicircular in shape. There are no hind-limbs upon the animal, but just behind the head are two powerful fins of an oval shape.
With these weapons it is enabled to hook out the small insects from the crevices of the bark, or grubs from the nests of bees or wasps. Like the squirrel, it sits upon its hind-limbs when eating, supporting itself with its prehensile tail. Its general colour is of a tawny hue, the under parts being white.
The majority resembled lizards and crocodiles in their general form, and many of them were, like crocodiles, protected by an armour of heavy bony plates. But, in others, the hind-limbs elongate and the fore-limbs shorten, until their relative proportions approach those which are observed in the short-winged, flightless, ostrich tribe among birds.

Even the term "Quadrumanous" has lately been shown by Professor Huxley, in a lecture delivered by him in the spring of 1860-61, which I had the good fortune to hear, to have proved a fertile source of popular delusion, conveying ideas which the great anatomists Blumenbach and Cuvier never entertained themselves, namely, that in the so-called Quadrumana the extremities of the hind-limbs bear a real resemblance to the human hands, instead of corresponding anatomically with the human feet.
