Antique printed color map from "The Physical Atlas of Natural Phenomena" by Alexander Keith Johnston, published by William Blackwood and Sons in 1856. This sheet features two maps: the upper map shows the depths of the Atlantic Ocean with deep-sea soundings made by the American Navy under the direction of Lieutenant Maury; the lower map shows a cross-section of the ocean depicting the depths and land in a condensed view. In very good antique condition with some overall toning and a few spots/smudges, this sheet measures approximately 22 x 14 inches to the paper edges.
