Scarce map of the World on a North Polar projection, which is intended to illustrate the watersheds of the World, as the water flows from the various mountain chains to the seas.
Each chain of mountains acts as a watershed to direct the flow of the rivers. Depicts the Sea of the West, incomplete Australia and a host of other interesting features. Potter 178-79. J.A. Dezauche was the successor to Guillaume De L'Isle and Philipe Buache. His maps retain the scientific precision of his predecessors.
Philippe Buache (1700-1773) was one of the most famous French geographers of the eighteenth century. Buache was married to the daughter of the eminent Guillaume Delisle and worked with his father-in-law, carrying on the business after Guillaume died. Buache gained the title geographe du roi in 1729 and was elected to the Academie des Sciences in the same year. Buache was a pioneering theoretical geographer, especially as regards contour lines and watersheds. He is best known for his works such as Considérations géographiques et physiques sur les découvertes nouvelles dans la grande mer (Paris, 1754).
