The name "soko" appears to be a local name for the ordinary type of chimpanzee found throughout the whole range of their domain, and known in other parts by other names. In Malimbu the name "kulu" appears to apply to the same species, while in the south-western part of their habitat that name, coupled with the verb "kamba," is confined strictly to the other type. Along the northern borders of the district to which that species belongs, but where he is very seldom found and little known to the natives, he is called Mkami tribe, "kanga ntyigo," to distinguish him from the common variety to which the latter name only is applied. The etymology of the name _kanga_ as applied to this ape is rather obscure. In common use it is a verb with the normal meaning to "parch" or "fry," and hence the secondary meaning to "prepare." Since this ape is said to be of a higher order of the race, the term is used to signify that he is "better prepared" than the other. That is to say, he is prepared to think and talk in a better manner. Another history of this word appears to be more probable. The ape to which the name is applied lives between the Mkami country and the Congo, and the name is possibly a perversion of kongo, and implies the kind of _ntyigo_ that lives towards the great river of that name. The etymology of African names is always difficult because there is no record of them, but many of them can be traced out with great precision, and some of them are unique. The name M'Bouvé, as given by Du Chaillu, I have not been able to identify. In one part of the country I was told that the word meant the "chief" or head of a family. In another part it was said to mean something like an advocate or champion, and was only applied to one ape in a family group. The Rev. A. C. Goode, a zealous missionary who recently died near Batanga, was stationed for twelve years at Gaboon. During that time he travelled all through the Ogowe and Gaboon valleys. He was familiar with the languages of that part, and he explained the word in about the same way. Whatever may be said concerning the veracity of Paul Du Chaillu, there is one thing that must be said to his credit. He gave to the world more knowledge of these apes than all other men put together had ever done before, and while he may have given a touch of colour to many incidents, and related some native yarns, he told a vast amount of valuable truth, and I can forgive him for anything which he may have misstated, except one. That is starting that story about gorillas chewing up gun-barrels. It has been a staple yarn in stock ever since, and the instant you ask a native any question about the habits of a gorilla he begins with this.
