the common name of ape, even in languages which have one name for apes without tails, and another for apes which have tails. They are both called by the name of _aff_ in German, and _ape_ in English; and it is only among the Greeks that we find that each of these animals has a proper name. The word cynocephalus is rather an adjective than a proper substantive, for which reason we have not adopted it. It appears from the testimonies of the ancients, that the pithecos, or pigmy, was the most gentle and docile of all the ape species that were known to them; and that it was common in Asia, as well as in Lybia, and in the other provinces of Africa, frequented by the Greek and Roman travellers. Therefore I presume that we must refer the following passages of Leo Africanus, and Marmol to the pigmy. They say, that the apes with long tails, which are seen in Mauritania, and are called by the Africans _mones_, come from the negro country; but that those without tails are found in great numbers, and are natives of the mountains of Mauritania, Bugie, and Constantine. "These animals, says Marmol, have feet and hands like a man, and, if I may be allowed the expression, a human face; they have an appearance of much vivacity, and seem very malicious. They live upon corn, herbs, and all sorts of fruits, to obtain which they sally forth in large troops, to plunder the gardens or fields; but before they venture out on these expeditions one of the company ascends an eminence, and surveys the country round. If there be no person near, he makes a signal by a cry, for his companions to proceed, remaining himself, however, at his station: but as soon as he perceives any one coming, he sets up a loud cry, and the whole company scamper off with the utmost precipitation, and jumping from tree to tree, retreat to the mountains. It is a great curiosity to see these animals retreat; for the females carry four or five young ones upon their backs, and with this heavy load, leap with great agility from branch to branch; yet great numbers of them are taken, by different snares, notwithstanding all their cunning. When they are angry, they bite furiously, but by coaxing, they are easily tamed. They do great damage to the gardens and fields, because they pluck, pull down, and tear up, every thing that comes in their way, whether ripe or not, and often destroy more than they can eat or carry away. Those that are tamed, perform things almost incredible, and imitate almost every human action!" Kolbe relates nearly the same facts with respect to the apes of the Cape of Good Hope: but the description and figure he gives of them, plainly prove they are baboons, having a short tail, a long muzzle, sharp nails, &c. they are also much larger and stronger than the apes of Mauritania. We may therefore presume, that Kolbe only copied this passage from Marmol, and applied the natural habitudes of the Mauritania pigmies to the baboons of the Cape of Good Hope.
