The Crocodile of the Nile is of a greenish yellow, variegated with pale green blotches and transverse lines; having, at a distance, the resemblance to brass slightly rusted. The under parts of the body, tail, feet, and inner sides of the legs are of a yellowish white. The Egyptian peasants often catch this tremendous animal by means of a strong rope, tied to the trunk of a large tree , having a hook at the other end, to which a living lamb is attached: this is left on the banks of the Nile till the Crocodile, attracted to the spot by the cries of the lamb, gorges it , and the hook becomes fixed. The more the Crocodile struggles to get free, the more firmly the hook penetrates. The peasants then give line, as the Crocodile retreats, watching all its motions in the water; and, when it is completely exhausted, they drag it on shore. It is singular, that the absurd assertion of Aristotle, respecting the under jaw of the Crocodile being immoveable, should have been believed for so long a succession of ages. The motion of the jaw of this animal is the same as that of all others. In some of the interior parts of Africa dogs are employed to hunt the Crocodile; but they are provided with strong iron collars, full of spikes, that they may be the better able to overcome so formidable an antagonist.
