The vicissitudes suffered by this famous architectural treatise, and especially the sources of the splendid re-edition published in 1925 were the subject of an earlier article in the Bulletin (Vol. IV, Pt. Ill (1927), pp. 473–92). A happy chance throws new light on the 1925 edition and allows me to add this note to what was said before. It is the presence in England of a sixteenth century manuscript copy of a part of the Ying tsao fa shih. If the editors of the 1925 edition had had access to this, they would doubtless have turned to it for data in their efforts to reconstruct the lost Sung original. At all events, the drawings it contains are of great interest to students of Chinese decorative design, for reasons to be mentioned presently.
