The Chinese Classics — Prolegomena
Chapter 5
These various readings are exceedingly few, and in themselves insignificant. The student who wishes to pursue this subject at length, is provided with the means in the Work of Ti Chiao-shau [2], expressly devoted to it. It forms sections 449- 473 of the Works of the Classics, mentioned at the close of the preceding section. A still more comprehensive work of the same kind is, 'The Examination of the Text of the Classics and of Commentaries on them,' published under the superintendence of Yuan Yuan, forming chapters 818 to 1054 of the same Collection. Chapters 1016 to 1030 are occupied with the Lun yu; see the reference to Yuan Yuan farther on, on p. 132.
