The "dromedary" of Egypt and Syria is not the two-humped animal described by that name in books of natural history, but is, in fact, of the same family as the camel, to which it stands in about the same relation as a racer to a cart-horse. The fleetness and endurance of this creature are extraordinary. It is not usual to force him into a gallop, and I fancy from his make that it would be quite impossible for him to maintain that pace for any length of time; but the animal is on so large a scale, that the jog-trot at which he is generally ridden implies a progress of perhaps ten or twelve miles an hour, and this pace, it is said, he can keep up incessantly, without food, or water, or rest, for three whole days and nights.
