A mid-18th century world map full of false assumptions

A double-hemisphere world map with the Americas in the right sphere, a decorative title cartouche, a world map is a single sphere in the lower cusp and geographical diagrams in the four corners.
What makes this map so fascinating is the amount of cartographical conjecture: at the Poles are various islands, including a huge one incorporating New Zealand; Australia's east coastline reaches Vanutu; in North America are the Mer de l'Ouest, Lac de Fonte and a large island instead of Alaska; in Africa a chain of mountains stretches across Guinea, thirty years before James Rennell was accused of inventing the 'Mountains of Kong'.
Although not listed in the list of sources, much of the information comes from Philippe Buache, 'Premier Géographe du Roi' from 1729. He believed that the mountains of the world were linked, crossing the ocean floors from continent to continent, most noticeably across the Pacific.
