“ The West African tribes speaking Mandingo languages vary very much in outward appearance. Some of them may be West African negroes of the forest type with little or no intermixture with the Caucasian; others, such as the typical Mandingos or the Susus, obviously contain a non-negro element in their physique. This last type resembles very strongly the Swahilis of the Zanzibar littoral or other crosses between the Arab and the negro; and though nearly always black-skinned, often has a well-shaped nose and a fairly full beard. ”
