The atlas is entitled "Atlas Universale de geographie, physique, politique, statistique et mineralogique sur l'echelle de 1/1641836 ou d'une ligne par 1900 toises". The lithographs were prepared by Henri Ode, also a member of the Royal Geographic Society of France. The map, which is entitled "Amer. Sep.

This covers the District of Keewatin and some of the District of Mackenzie - and includes Chesterfield Inlet, Baker Lake and Dubawnt Lake).
