[16] Weisbach, 1882; Nicolucci, 1867; Apostolides in Bull. Soc. d'Anth., 1883, p. 614; Stephanos, 1884; Neophytos, 1891; Lapouge, 1896 a, p. 419. Von Luschan, 1889, p. 209, illustrates the similarity between the Greek and the Bedouin skull. [17] 1889, p. 209. [18] Neophytos finds 82.5 per cent of dark-brown or black hair, only five per cent blond or red; while seventeen per cent of the eyes were dark among two hundred individuals. [19] 1886 b, p. 637. [20] Vambéry, 1885, divides the Ural-Altaic family into five groups--viz., (1) Samoyed, (2) Tungus, (3) Finnic, (4) Mongolic, (5) Turkish or Tatar. [21] On terminology consult Vambéry, 1885, p. 60; Chantre, 1895, p. 199; Keane, 1897, p. 302. [22] Complete data on these people will be found in Ujfalvy, 1878-'80, iii, pp. 7-50; Les Aryens, etc., 1896, pp. 385-434; Bogdanof, 1888; Yavorski, 1897. [23] Ujfalvy (Les Aryens, etc., 1896, p. 428) found chestnut hair most frequent, with twenty-seven per cent of blondness, among some of the Tadjiks. The eyes are often greenish gray or blue (Ujfalvy, 1878-'80, iii, pp. 23-33, tables). [24] On the anthropology of European Turks, Weisbach, 1873, is the only authority. He found an average cephalic index of 82.8 in 148 cases. Elisyeef, 1890-'91, and Chantre, 1895, pp. 206-211, have worked in Anatolia, with indices of 86 for 143 individuals, and 84.5 for 120 men, respectively. Both von Luschan and Chantre give a superb collection of portrait types in addition. [25] Read Pruner Bey, 1860 b; Howorth; Obédénare, and especially Kanitz, 1875, for historic details. [26] 1889 a, with map, in Petermann, 1889 b. Cf. criticism of his contention by Oppel, 1890; Couvreur, 1890, p. 523; and Ghennadieff, 1890, p. 663. [27] Auerbach, 1898, p. 286, gives a full summary of the rival controversy between Roumanians and Hungarians as to priority of title in Transylvania. [28] Cf. Picot, 1883, in his review of Tocilescu; and Rosny, 1885, p. 83. [29] Picot, 1875, pp. 390 _et seq._ [30] Auerbach, 1898, p. 211. [31] 1891, p. 30. Dr. Bassanovitch has most courteously sent me a sketch map showing the results of these researches. Deniker, 1897, p. 203, and 1898 a, describes them also. [32] Deniker, 1898 a, p. 122; Weisbach, 1877, p. 238; Rosny, 1885, p. 85. [33] 1879, p. 233. [34] 1893, p. 282. [35] Popular Science Monthly, October, 1898, p. 734. [36] 1891, p. 31. Women dolicho-, twenty-five per cent; meso-, forty-two per cent; brachy-cephalic, thirty per cent; while among men the percentages are 3, 16, and 81 ± per cent respectively. [37] Popular Science Monthly, January, 1899, p. 350. [38] Bassanovitch's series of 1,955 individuals averages only 1.638 metre. _Op. cit._, p. 30. Auerbach, 1898, p. 259, gives an average of 1.63 metre for 880 Wallachians in Transylvania. Obédénare, 1876, p. 374, states brown eyes to be most frequent in Roumania.
