= Rare Dutch edition. Cat. NHSM I, p.134; Tiele 61; Cordier, Bibl. Sinica p.2089; Henze I, p.118/119; cf. Lust 311/ 312 and Cox I, p.75f for the English and French eds. "Since Avril's book was to be a guide for missionaries getting to China by overland routes, it is particularly strong on the Russian side, and the fringe regions of north and northwest China. Somewhat muddled but interesting on Jesuit outlooks, and on advances in Asian geography." (Lust).
