A second attempt at a bathymetric map by Matthew Fontaine Maury

A second attempt at a bathymetric map by Matthew Fontaine Maury. Published in “The Physical Geography of the Sea” with black and grey shading. Showed vast relatively shoal area in Mid-Atlantic which gave birth to the notion of a “Telegraphic Plateau”. The shoal area was actually part of the Mid-Atlantic Ridge discovered by Otway Berryman in 1853.
