While originally believing that the Egyptians were purely Caucasian, the authors of
Types of Mankind (1854) modified their views based on excavations from earlier dynasties. In their view, the earliest Egyptians were neither Caucasian or Negro but an intermediate Negroid type. However, they still believed that pure Negroes existed in Egypt only as slaves: Specifically, in 1854, Josiah Nott and George R. Gliddon noted that according to majority of ethnographers and Samuel George Morton's own anthropological works, "the Fellahs of Upper and Middle Egypt, at the present day, continue to be an unmistakable race, and are regarded by most travelled authorities as the best living representatives of the ancient population of Egypt." They would also take the position that, "the iconographic monuments of the IVth, Vth, and VIth dynasties, is closely analogous to the predominant type of that day; which fact serves to strengthen our view that the Egyptians of the early dynasties were rather of an African or Negroid type-resembling the
Bishari in some respects, and in others the
modern Fellah, or peasantry of Upper Egypt." In the 19th century the word "Negro" is reserved only for people who display the highest degree of stereotypical black African characteristics, with the suffix
oid in "Negroid" making the word literally mean "Negro like". From the 1911 Encyclopædia Britannica "It is most convenient, however, to refer to the dark-skinned inhabitants of this zone by the collective term of Negroids, and to reserve the word Negro for the tribes which are considered to exhibit in the highest degree the characteristics taken as typical of the variety."
Samuel Morton addressed several letters to George Gliddon and stated that he modified many of his old views on ancient Egypt, believing their origins to be similar to
Barabra populations, but not Negroes. ==Personal life==
