In the various records that constitute the history of these apes are found many novel and incoherent tales, but all of them appear to rest upon some basis of truth. In order to arrive at some more definite knowledge concerning them, we may review the data at our command. The first record in the annals of the world that alludes to these man-like apes, is that of Hanno, who made a voyage from Carthage to the west coast of Africa, nearly 500 years before the Christian era. He described an ape which was found in the locality about Sierra Leone. It is singular that the description which he gave of those apes should coincide so fully with those known of the present day, but to my mind it is quite certain that the ape of which he gives an account was neither a gorilla nor chimpanzee, nor is there anything to show that either of these ever occupied that part of the world, or that any similar type has done so. It is clear from the evidence that the ape described by him was not an anthropoid, but was the large, dog-faced monkey technically called _cynocephalus_. These animals are found all along the north coast of the Gulf of Guinea, but there is not a trace of any true ape along it north of Cameroon River, which empties into the sea about 4° north of the equator. Here begins the first trace of the chimpanzee. In passing along the windward coast, casual reports are current to the effect that gorillas and chimpanzees occupy the interior north of there; but when these reports are sifted down to solid facts, it always turns out to be a big baboon or monkey upon which the story rests. Its likeness to man as described by Hanno was doubtless the work of fancy, and the name _troglodytes_ which he gave to it shows that he knew but little of its habits, or cared but little for the exactness of his statements.
