"On the coasts of the river Gambia (says Froger) there are apes larger and more mischievous than in any other part of Africa: the negroes are afraid of them, and they cannot travel alone where they frequent, without running a risk of being attacked by these animals, who make use of huge clubs. The Portuguese say that they frequently take away young girls of seven or eight years of age, and carry them up to the highest trees. Most of the negroes regard these animals as foreigners who are come to establish themselves in their country, and that their not speaking arises from a fear of being obliged to work." Another traveller remarks, that at Macacar there are apes which walk upon their hind-feet like the human species, that they go in numbers, and that an encounter with them often proves fatal. Thus we have nearly given every particular circumstance concerning this animal which has been related by travellers who may be the most depended upon. I have given their accounts entire, because every passage is important in the history of a brute which has so great a resemblance to man; and in order to determine its nature with the greater certainty, we shall now mention those differences and conformities which divide him from or give him an approximation to the human species. The first external difference is the flatness of the nose, the shortness of the forehead, and the defect of prominence in the chin. The ears are proportionally too large, the eyes too close to each other, and the interval between the nose and the mouth too great: these are the only differences between the face of the orang-outangs and that of man. With regard to the body and limbs, the thighs are proportionally too short, the arms too long; the fingers too small, the palms of the hands too narrow, and the feet rather resemble the hands than the human feet. The parts of generation differ only from those of man, by their having no frænum to the prepuce; but in the females the organs externally are nearly like those of women.
