V. Commentaries on the Principles of Sun Yat-sen. Li Ti tsun; _The Politico-Economic Theories of Sun Yat-sen_. This work has not been published, but portions of it appeared in the _Chinese Students’ Monthly_, XXIV, New York, 1928-1929, as follows: “The Life of Sun Yat-sen,” no. 1, p. 14, November, 1928; “The Theoretical System of Dr. Sun Yat-sen,” no. 2, p. 92, December 1928, and no. 3, p. 130, January 1929; and “The Sunyatsenian Principle of Livelihood,” no. 5, p. 219, March 1929. It is most regrettable that the whole work could not be published as a unit, for Li’s work is extensive in scope and uses the major Chinese and foreign sources quite skilfully. Tai Chi-tao (Richard Wilhelm, translator); _Die Geistigen Grundlagen des Sunyatsenismus_, Berlin, 1931. An informative commentary on the ethical system of Sun Yat-sen. Tai Chi-tao is an eminent Party leader. Antonov, K.: _Sun’iatsenizm i kitaiskaia revoliutsiia_, Moscow, 1931. Not available to the author. William, Maurice; _Sun Yat-sen Vs. Communism_, Baltimore, 1932. A presentation, by the author of _The Social Interpretation of History_, of the influence which that work had on Sun; useful only in this connection. Linebarger, Paul; Linebarger, Paul M. A. (editor); _Conversations With Sun Yat-sen_, 1919-1922. For comment on this and the following manuscript, see Preface. Linebarger, Paul; _A Commentary on the San Min Chu I_. Four volumes, unpublished, 1933. Tsui, Shu-Chin, _The Influence of the Canton-Moscow Entente upon Sun Yat-sen’s political Philosophy_, in _The Chinese Social and Political Science Review_, XVIII, 1, 2, 3, Peiping, 1934.

Ranks with the works of Tai Chi-tao, Hsü Shih-lien, and Father d’Elia as an aid to the understanding of the Three Principles. Jair Hung: _Les Idées Économiques de Sun Yat Sen_, Toulouse, 1934.
