23 : 8. Clark Wissler, in _The American Indian_, makes clear the general uniformity of American Indian types in chap. XVIII. See also Haddon, 1, p. 8, and Hrdlička, _The Genesis of the American Indian_, pp. 559 _seq._ 23 : 13. Haddon, 1, pp. 10 and 11. There are numerous other references to this fact, especially in articles in various anthropological journals, and general works on anthropology, such as those of Deniker, Collignon, Martin and Ratzel. 23 : 16. For the differentiation of skull types in Europe during the Paleolithic period, see Keith, 2, the chapters on Pre-Neolithic, Mousterian and Neanderthal man; and 1, pp. 74 _seq._; as well as Osborn, 1, who also gives the dates of the Paleolithic in the table on p. 18. 24 : 3–5. This claim was put forth by Sergi, in his _Mediterranean Race_, pp. 252, 258–259, and was followed by Ripley in his _Races of Europe_. 24 : 14. Deniker, _Races of Man_, pp. 48–49; Ripley, p. 465. 25 : 5. Topinard, 1, 4; Collignon, 1; and Virchow, 1, p. 325; Ripley, p. 64. Ripley says: “If the hair be light, one can generally be sure that the eyes will be of a corresponding shade. Bassanovitch, ... p. 29, strikingly confirms this rule even for so dark a population as the Bulgarian.” 25 : 6. See p. 163 of this book on the Albanians. 25 : 8. Ripley, pp. 75–76 and the footnote on p. 76. 25 : 11. Deniker, 2, p. 51. Also Davenport, _passim_. 25 : 13. Sir Edmund Loder, in correspondence, February, 1917, asks: “Has it been noticed at Creedmore and elsewhere in America that nearly all noted shots have blue eyes? It has been very noticeable at Wimbledon and Bisby, where it was quite exceptional to find a man in the front rank of marksmen with dark colored eyes. There was, however, one man who shot in my team who had very dark eyes and was one of the best shots of the day.” 25 : 16. There are said to be blue eyes occasionally in other races, where traces of Nordic blood cannot be discovered. Green and blue eyes have been found among the Rendeli (Desert Masai), although they are otherwise normal negroes. 25 : 19. The following quotation is from Von Luschan, 1, p. 224: “In Marmaritza near Halikarnassos, where a British squadron had a winter station for many years, a very great proportion of the children is said to be ‘flaxen-haired.’” According to a statement made to the author by Professor G. Elliot Smith on May 4, 1920, a similar nest of blondness is found in the Egyptian delta near Aboukir and is due to the fact that after the battle of the Nile the Seaforth Highlanders were long stationed there. At one time this blondness was supposed to bear some relation to the ancient Lybian blondness depicted on the monuments.
