Senegal, River of, African river. It takes its source from the middle of Nigritia (interior of the continent), runs toward the west, forms at its mouth the small island of Senegal , and empties into the ocean after a course of three to four hundred leagues. This large river separates the Moors, or dark-skinned individuals (bazanés), from the Negroes; such that on one side of the river there are yellowish Moors and on the other, completely black men; the first are wandering and free; the Negroes are sedentary and have kings who make them slaves. The Moors are small, thin, of fine and nimble mind; the Negroes are large, fat, and without genius.
