The Unicorn seems to have been a sad trouble to the hunters, who hardly knew how to come at so valuable a piece of game. Some described the horn as moveable at the will of the animal--a kind of small sword, in short, with which no hunter who was not exceedingly cunning in fence could have a chance. Others told the poor foresters that all the strength lay in its horn, and that when pressed by them it would throw itself from the pinnacle of the highest rock, horn foremost, so as to pitch upon it, and then quietly march off not a bit the worse! Modern zoologists, disgusted as they well may be with fables, such as we have glanced at, disbelieve, generally, the existence of the Unicorn, such, at least, as we have referred to; but there is still an opinion that some land animal bearing a horn on the anterior part of its head, exists besides the rhinoceros. The nearest approach to a horn in the middle of the forehead of any terrestrial mammiferous animal known to us is the bony protuberance on the forehead of the giraffe; and though it would be presumptuous to deny the existence of a one-horned quadruped other than the rhinoceros, it may be safely stated that the insertion of a long and solid horn in the living forehead of a horse-like or deer-like cranium is as near an impossibility as anything can be. Rupell, after a long sojourn in the north-east of Africa, stated that in Kordofan the Unicorn exists; stated to be the size of a small horse, of the slender make of the gazelle, and furnished with a long straight horn in the male, which was wanting in the female. According to the statements made by various persons, it inhabits the deserts to the south of Koretofan, is uncommonly fleet, and comes only occasionally to the Koldagi Heive mountains on the borders of Kordofan. Other writers refer the Unicorn to the antelope. The origin of the name of antelope is traced by Cuvier to the Greek _Anthalops_, applied to a fabulous animal living on the banks of the Euphrates, with long jagged horns, with which it sawed down trees of considerable thickness! Others conjecture this animal to have been the _Oryx_, a species of antelope, which is fabulously reported to have had only one horn, and to have been termed _Panthalops_ in the old language of Egypt.
