philosophy I adapted ideas from Chan Wing-sit.

p. 219: A comprehensive study of Chu Hsi is a great desideratum. Thus
far, we have in English mainly the essays by Feng Yu-lan (transl. and
annotated by D. Bodde) in the _Harvard Journal of Asiat. Stud_., vol. 7,
1942. T. Makino emphasized Chu's influence upon the Far East, J. Needham
his interest in science.

p. 220: For Su Tung-p'o as general introduction see Lin Yutang, _The Gay
Genius. The Life and Times of Su Tung-p'o_, New York 1947.--For
painting, I am using concepts of A. Soper here.

p. 222: For this period the standard work is K.A. Wittfogel and Feng
Chia-sheng, _History of Chinese Society, Liao_, Philadelphia
1949.--Po-hai had been in tributary relations with the dynasties of
North China before its defeat, and resumed these from 932 on; there were
even relations with one of the South Chinese states; in the same way,
Kao-li continuously played one state against the other (M. Rogers _et
al_.).

p. 223: On the Kara-Kitai see Appendix to Wittfogel-Feng.

p. 228: For the Hakka, I relied mainly upon Lo Hsiang-lin; for Chia
Ssu-tao upon H. Franke.

p. 229: The Juchen (Jurchen) are also called Nue-chih and Nue-chen, but
Juchen seems to be correct (_Studia Serica_, vol. 3, No. 2).

_Chapter Ten_

p. 233: I use here mainly Meng Ssu-liang, but also others, such as Chue
Ch'ing-yuean and Li Chien-nung.--The early political developments are
described by H.D. Martin, _The Rise of Chingis Khan and his Conquest of
North China_, Baltimore 1950.

p. 236: I am alluding here to such Taoist sects as the Cheng-i-chiao
(Sun K'o-k'uan and especially the study in _Kita Aziya gakuh[=o]_, vol. 2).

pp. 236-7: For taxation and all other economic questions I have relied
upon Wan Kuo-ting and especially upon H. Franke. The first part of the
main economic text is translated and annotated by H.F. Schurmann,
_Economic Structure of the Yuean Dynasty_, Cambridge, Mass., 1956.

p. 237: On migrations see T. Makino and others.--For the system of
communications during the Mongol time and the privileges of merchants, I
used P. Olbricht.

p. 238: For the popular rebellions of this time, I used a study in the
_Bull. Acad. Sinica_, vol. 10, 1948, but also Meng Ssu-liang and others.

p. 239: On the White Lotus Society (Pai-lien-hui) see note to previous
page and an article by Hagiwara Jumpei.

Bruges 1959, has studied in
