First editions of two works by the great French cartographer d'Anville, who was engaged by the Jesuits to produce three maps based on the findings of the Jesuit missionaries to China, for inclusion in Pierre Du Halde's 'Description géographique... de l'Empire de la Chine et de la Tartarie Chinoise' (1735). These were subsequently revised for the 'Nouvel atlas de la Chine' (1737). In the 'Mémoire' he provided a comprehensive explanation for his methodology in preparing the maps, the sources he had chosen to draw from and an overview of earlier expeditions undertaken to China and Tibet.
