I AM in thorough accord with the main principles indicated in Dr. A. C. Haddon's communication, which appeared in NATURE, vol. lxiii. p. 309 (January 24), more especially as to the eastern extension of a fair dolichocephalic race or races, at least as far east as the north-western frontiers of China. It has, however, always struck me, as a student of the ethnology of these districts, that
... [Show full abstract] sufficient attention has not been given to the geographical changes that have certainly occurred throughout the whole of Central Asia, and without which it appears impossible to understand such writers as Herodotus, Arrian and Ammianus Marcellinus. I claim no new discovery in suggesting, with Colonel Tchaikofsky (quoted by Schuyler, vol. i. p. 53), that during the Classical period the rivers Chu and Sary-su, instead of losing their waters in desert lakes, united at Perovsky with the Jaxartes, and flowed along the deserted bed, now known as the jany Darya, joining finally the old Oxus and making their way along what is still known as the ``Ancient Bed'' of the Amu Darya to the Caspian. We thus arrive at a satisfactory explanation of the crossing of the ``Araxes'' by Cyrus, and his description of the homeland of the Massagetæ, whom we are then justified in associating ethnologically with the Getæ or Goths of other authors. This would throw light also on the position of Arrian's Alexandria Eschate, which I would identify with the modern Jizakh. This was situated on the Tanais, which seems to have been an overflow channel of the upper Jaxartes, leaving the main river at the bend below Khojend and flowing past Jizakh into the Taz Khane, whence it found its way into the Jany Darya.
