574. The deepest imrt of the Ailanilc Ocean. — The greatest 

 depths at which the bottom of the sea has been reached with 

 the plummet are in the North Atlantic Ocean, and the places 

 where it has been fathomed do not show it to be deeper than 

 twenty-five thousand feet. The deepest place in this ocean 

 (Plate XI.) is probably between the parallels of 35° and 40° 

 north latitude, and immediately to the southward of the Grand 

 Banks of Newfoundland. The first specimens have been 

 received from the coral sea of the Indian Archipelago and from 

 the North Pacific. The}^ were collected by the surveying 

 expedition employed in those seas. A few soundings have been 

 made in the South Atlantic, but not enough to justify deduction 

 as to its depths or the precise shape of its floor.

 physical research at sea are under obligations to the officers
