e, but also upon O. Franke.

p. 169: The relevant texts concerning the T'u-chueeh are available in
French (E. Chavannes) and recently also in German translation (Liu
Mau-tsai, _Die chinesischen Nachrichten zur Geschichte der Ost-T[vu]rken_,
Wiesbaden 1958, 2 vol.).--The Toeloes are called T'e-lo in Chinese
sources; the T'u-yue-hun are called Aza in Central Asian sources (P.
Pelliot, A. Minorsky, F.W. Thomas, L. Hambis, _et al_.). The most
important text concerning the T'u-yue-hun had been translated by Th. D.
Caroll, _Account of the T'u-yue-hun in the History of the Chin Dynasty_,
Berkeley 1953.

p. 171: The transcription of names on this and on the other maps could
not be adjusted to the transcription of the text for technical reasons.

p. 172: It is possible that I have underestimated the role of Li Yuean. I
relied here mainly upon O. Franke and upon W. Bingham's _The Founding of
the T'ang Dynasty_, Baltimore 1941.

p. 173: The best comprehensive study of T'ang economy in a Western
language is still E. Balazs's work. I relied, however, strongly upon Wan
Kuo-ting, Yang Chung-i, Kat[=o] Shigeru, J. Gernet, T. Naba, Niida
Noboru, Yoshimi Matsumoto.

pp. 173-4: For the description of the administration I used my own
studies and the work of R. des Rotours; for the military organization I
used Kikuchi Hideo. A real study of Chinese army organization and
strategy does not yet exist. The best detailed study, but for the Han
period, is written by H. Maspero.

p. 174: For the first occurrence of the title _tu-tu_ we used W.
Eichhorn; in the form _tutuq_ the title occurs since 646 in Central Asia
(J. Hamilton).

p. 177: The name T'u-fan seems to be a transcription of Tuepoet which,
in turn, became our Tibet. (J. Hamilton).--The Uighurs are the Hui-ho or
Hui-hu of Chinese sources.

p. 179: On relations with Central Asia and the West see Ho Chien-min and
Hsiang Ta, whose classical studies on Ch'ang-an city life have recently
been strongly criticized by Chinese scholars.--Some authors (J.K.
Rideout) point to the growing influence of eunuchs in this period.--The
sources paint the pictures of the Empress Wu in very dark colours. A
more detailed study of this period seems to be necessary.

p. 180: The best study of "family privileges" (_yin_) in general is by
E.A. Kracke, _Civil Service in Early Sung China_, Cambridge, Mass. 1953.

p. 180-1: The economic importance of organized Buddhism has been studied
by many authors, es
