In the First Book of this volume, the most interesting quotation concerning the dragon in China are systematically arranged, selected from the enormous number of passages on this divine animal found in Chinese literature from the remotest ages down to modern times. In order to give the original conceptions the author did not quote the numerous poems on the dragon, because the latter, although based upon those conceptions, enlarged them in their own poetical way. The Second Book treats of the dragon in Japan, considered in the light of the facts given by the Introduction and Book I.
