There is mention made in Holy Scripture of the fiery flying-serpent, a creature about whose existence and qualities naturalists have entertained a considerable difference of opinion. It is now generally admitted, that, in Guinea, Java, and other countries, where there is at once great heat and a marshy soil, there exists a species of these animals, which have the power of moving in the air, or at least of passing from tree to tree. Niebuhr relates, that at Bazra, also, "there is a sort of serpents, called _heie sursurie_. They commonly live on dates; and as it would be troublesome to them to come down one high tree and creep up another, they hang by the tail to the branch of one, and, by swinging that about, take advantage of its motion to leap to that of a second. These the modern Arabs call flying-serpents--_heie thiâre_. I do not know whether the ancient Arabs were acquainted with any other kind of flying-serpent."[201] Near Batavia there are certain flying-snakes, or dragons, as they are sometimes called. They have four legs, a long tail, and their skin speckled with many spots; their wings are not unlike those of a bat, which they move in flying, but otherwise keep them almost unperceived, close to the body. They fly nimbly, but cannot hold out long; so that they only shift from tree to tree at about twenty or thirty yards' distance. On the outside of the throat are two bladders, which, being extended when they fly, serve them instead of a sail.[202] The _scorpion_, or okrab of the Hebrews, has also been invested by Oriental naturalists with the power of flying. Lucian tells us that there are two kinds of scorpions, one residing on the ground, large, having claws, and many articulations at the tail; the other flies in the air, and has inferior wings like locusts, beetles, and bats. In tropical climates the scorpion is a foot in length. No animal in the creation seems endowed with such an irascible nature. When caught, they exert their utmost rage against the glass which contains them; will attempt to sting a stick when put near them; will, without provocation, wound other animals confined with them; and are the cruellest enemies to each other. Maupertuis put a hundred of them together in the same glass; instantly they vented their rage in mutual destruction, universal carnage! In a few days only fourteen remained, which had killed and devoured all the others. It is even asserted, that when in extremity or despair the scorpion will destroy itself. Well might Moses mention this animal as one of the dangers of the howling wilderness! They are still very numerous in the desert between Syria and Egypt. Dr. Clarke tells us that one of the privates of the British army, who had received a wound from one of them, lost the upper joint of his forefinger before it could be healed. The author of the Revelation considers them as emblematic of the evils which issue from the bottomless pit. "And there came out of the smoke locusts
