Appendix C] CHINESE TURKESTAN AND THE PAMIRS 1355
the fact that the extremes are constituted by two members of the desert population. As in the case of the total facial length, the Pamir peoples on the whole mass themselves towards the lower end of the scale, while the Kelpin, Kirghiz, Ak-su, Faizabad, and Dolan are distributed in ascending order about the central portion. An important difference is constituted by the fact that the Chinese and Loplik in this case lie next one to another each with a high figure.
Upper Facial Index.
Tables 5 and 8.—Extremes, Kirghiz and Dolan (46), Chitrali (56). This index gives a verdict very similar to the total facial, with one very important difference, viz.: that the Chinese and Loplik are again brought closely together. This shows that the difference existing between them lies solely in the superior length of the chin among the Chinese. Again the Kirghiz, Dolan, Kelpin, Faizabad, and Ak-su form the most euryprosopic group, the Pamir people the most leptoprosopic, though the Sarikoli stand a little apart. Bagh-jigda also has a low index, and the Chinese an even lower. The desert folk occupy the centre of the scale, Polu extending into the euryprosopic portion, Kök-yar into the leptoprosopic. Nissa and Karanghu-tagh are on the leptoprosopic side of the centre, as is also Hami, doubtless, as regards the latter, owing to the influence of the Chinese.
Tables 5 and 7.—Extremes, Kök-yar (537), Loplik (576). Here M shows great variation, which unfortunately is obviated by an almost more than proportional variability. The Chinese and Loplik fall together, but the Pamir peoples are divided into two, the Mastuji, Kafir, and Chitrali showing a high figure, the Pakhpu and Sarikoli a low. The members of the Kirghiz group are distributed at intervals about the central portion. Owing, however, to the great variability, due possibly in part to the difficulty of making accurate measurements, the evidence afforded by these figures is not of great value.
Tables 6 and 8.—Extremes, Nissa (16o), Loplik (17o). Also a measurement of no great value, owing to the slight variation of M and its great individual variability. The Ak-su, Kirghiz, Dolan, and Kelpin form a group on the short side of the centre. The Pamir peoples and the desert folk are distributed fairly equally along the whole line. All that can be said is that the former tend to mass towards the tall end, the latter towards the short.
Tables 6 and 8.—Extremes, Nissa (16o), Faizabad (173). Again the Pamir mountaineers show a wide distribution, with a tendency to mass towards the higher end of the scale. This tendency is even more marked among the Kirghiz group, while the desert peoples are nearly all at the other end. The Chinese and Loplik show considerable divergence.
Tables 6 and 8.—Extremes, Keriya (99), Kelpin (104). This shows a result more in accordance with the more important measurements. With the Kelpin are grouped Faizabad, Kirghiz, Ak-su, and Dolan, all having a high index. This group is overlapped by Bagh-jigda, which is followed by the Pamir peoples, Kafir, Mastuji, Chitrali, Sarikoli, Wakhi, and Pakhpu, in their turn overlapped by Kök-yar, Charkhlik, and Niya. The Loplik and Chinese fall towards the other end, and beyond them come Karanghu-tagh and Nissa.
The Differential Index.
Table 9 shows the 20 for each pair of tribes, obtained as described on p. 1352. Any :SA which contains among its factors a 0 amounting to 1, or over, is printed in italics, unless the 6, which reaches a whole number is that derived from the head-circumference. An exception has been made in this case owing to the great individual variability of this measurement. Another exception is furnished by the 2,0 for Keriya and Niya. In this case 0 for the stature-span index is Poo, yet the M for Keriya is calculated from only five individuals, and the variability of this measurement is great in proportion to the small difference which exists between the extremes. Moreover the population respectively of Keriya and Niya show remarkably little difference in other respects
