CHAPTER X 



The Chimpanzee — The Name — Two Species — The Kulu-Kamba 

 Distribution — Color and Complexion 



NEXT to man the chimpanzee occupies the highest 

 plane in the scale of nature. His mental and 

 social traits, together with his physical type, assign him to 

 this place. 



In his distribution he is confined to equatorial Africa. 

 His habitat, roughly outlined, is from the fourth parallel 

 north of the equator to the fifth parallel south of it, along 

 the west coast, and extends eastward a little more than 

 halfway across the continent. His range cannot be 

 defined with precision, for its exact limits are not yet 

 known. Its boundary on the north is defined by the 

 Cameroon valley, slightly curving towards the north ; but 

 its extent eastward is a matter of some doubt. He does 

 not appear to be found anywhere north of that river, and 

 it is quite certain that the few specimens attributed to the 

 north coast of the Gulf of Guinea do not belong to that 

 territory. On the south the boundary of his habitat starts 

 from the coast, at a point near the fifth parallel, curves 

 slightly northward, crosses the Congo near Stanley Pool, 

 pursues a northeasterly course to about the middle of the 

 Congo State, and again curves southward across the Upper 

 Congo, not far from the north end of Lake Tanganyika.
