this book and in an article the fate of
isolated Mongol groups in China after the breakdown of the dynasty.

pp. 241-2: The travel report of Ch'ang-ch'un has been translated by A.
Waley, _The Travels of an Alchemist_, London 1931.

p. 242: _Hsi-hsiang-chi_ has been translated by S.I. Hsiung. _The
Romance of the Western Chamber_, London 1935. All important analytic
literature on drama and theatre is written by Chinese and Japanese
authors, especially by Yoshikawa Kojiro.--For Bon and early Lamaism, I
used H. Hoffmann.

p. 243: Lamaism in Mongolia disappeared later, however, and was
reintroduced in the reformed form (Tsong-kha-pa, 1358-1419) in the
sixteenth century. See R.J. Miller, _Monasteries and Culture Change in
Inner Mongolia_, Wiesbaden 1959.

p. 245: Much more research is necessary to clarify Japanese-Chinese
relations in this period, especially to determine the size of trade.
Good material is in the article by S. Iwao. Important is also S. Sakuma
and an article in _Li-shih yen-chiu_ 1955, No. 3. For the loss of coins,
I relied upon D. Brown.

p. 246: The necessity of transports of grain and salt was one of the
reasons for the emergence of the Hsin-an and Hui-chou merchants. The
importance of these developments is only partially known (studies mainly
by H. Fujii and in _Li-shih-yen-chiu_ 1955, No. 3). Data are also in an
unpublished thesis by Ch. Mac Sherry, _The Impairment of the Ming
Tributary System_, and in an article by Wang Ch'ung-wu.

p. 247: The tax system of the Ming has been studied among others by
Liang Fang-chung. Yoshiyuki Suto analysed the methods of tax evasion in
the periods before the reform. For the land grants, I used Wan
Kuo-ting's data.

p. 248: Based mainly upon my own research. On the progress of
agriculture wrote Li Chien-nung and also Kat[=o] Shigeru and others.

p. 250: I believe that further research would discover that the
"agrarian revolution" was a key factor in the economic and social
development of China. It probably led to another change in dietary
habits; it certainly led to a greater labour input per person, i.e. a
higher number of full working days per year than before. It may be--but
only further research can try to show this--that the "agrarian
revolution" turned China away from technology and industry.--On cotton
and its importance see the studies by M. Amano, and some preliminary
remarks by P. Pelliot.

pp. 250-1: Detailed study of Central Chinese urban centres
