Bendix, _Max Weber, an Intellectual Portrait_, Garden City 1960, p. 117-157). Early administration systems of this type in China have been studied in several articles in the journal _Yue-kung_ (vol. 6 and 7).

p. 65: In the discussion of language, I use arguments which have been brought forth by P. Serruys against the previously generally accepted theories of B. Karlgren.--For weights and measures I have referred to T. Sekino, Liu Fu and Wu Ch'eng-lo.

p. 66: For this period, D. Bodde's _China's First Unifier_, Leiden 1938 and his _Statesman, Patriot, and General in Ancient China_, New Haven 1940 remain valuable studies.
