25 : 25 _seq._ On the Berbers see Sergi, 4, pp. 59 _seq._, and Topinard, 3. In regard to the Albanians, Ripley refers to their blondness, on p. 414, as follows: “The Albanian colonists, studied by Livi and Zampa in Calabria, still, after four centuries of Italian residence and intermixture, cling to many of their primitive characteristics, notably their brachycephaly and their relative blondness.” See also Zampa, 1, and Deniker, 1, for scientific discussions of their physical characters. Giuffrida-Ruggeri gives a summary of the most recent literature on Albania. 25 : 29–26: 6. See Beddoe, _The Races of Britain_, pp. 14, 15 and _passim_. 26 : 18. Beddoe, 4, p. 147. 27 : 1 _seq._ See Ripley, pp. 399–400 for a summary of observations on this point. See also Darwin, _Descent of Man_, pp. 340–341 and 344 _seq._; and Fleure and James, p. 49. 27 : 14–28: 19. Haddon, 1, p. 2; also 2; Deniker, 2, chap. II and _passim_. 28 : 19.

Also see Davenport and Conklin, _passim_, and the notes to p. 18 of this book. 30 : 18–31: 8. For a very interesting discussion of this question see Conklin, 2, vol. IX, no. 6, pp. 492–6; Deniker, 2, p. 18; Haddon, 2, chap. IV; and Louis R. Sullivan, _The Growth of the Nasal Bridge in Children_, are other authorities. Some special studies of the nose have been made by Majer and Koperniki, Weisbach, and Olechnowicz, for which see Ripley, pp. 39 4–395. Jacobs, pp. 23–62, is particularly good on nostrility. 31 : 9. Deniker, 2, p. 83. 31 : 13. On the shape of the foot as a racial character see Rudolf Martin, _Lehrbuch der Anthropologie_, pp. 317 _seq._; and Beddoe, 4, pp. 245 _seq._; W. K. Gregory, 2, p. 14, and John C. Merriam, vol. IX, pp. 202 _seq._, have both discussed the evolution of the foot and the hand, and the anatomical differences which distinguish those of man from those of the apes. 31 : 16. P. Topinard, 2, chap. X, and Rudolf Martin, pp. 367 _seq._ 32 : 4. Beard lighter than head hair. Darwin, _Descent of Man_, p. 850. 32 : 8. The red-haired branch of the Nordics.
