I believe the depth in th Atlantic Ocean to be nearly four thousand fathoms, and about 1,2000 fathoms in the Mediterranean, but the deepest levels of the sea are known to be in the South Atlantic Ocean, nearly 7,500 fathoms, or one and three quarter leagues.

The Nautilus was traveling southeast, usually sailing between three hundred and four hundred and fifty feet below the surface of the water. By the 27th of the November, we were traveled over 4,860 leagues from our starting poiot. From the 4th to 11th of the December, the Natilus sailed over 2,000 miles.
