Or NOAH'S ARK, a floating vessel built by Noah for the preservation of his family, and the several species of animals, during the deluge. The form of the Ark was an oblong, with a flat bottom, and a sloped roof, raised to a cubit in the middle; it had neither sails nor rudder; nor was it sharp at the ends for cutting the water. This form was admirably calculated to make it lie steady on the water, without rolling, which might have endangered the lives of the animals within. The length of this ark was 300 cubits, which according to Dr. Arbuthnot's calculation, amount to a little more than 547 feet; its breadth, 50 cubits, or 54-72 feet; and its solid contents 2, 730-782 solid feet, sufficient for a carriage for 81, 062 ton. It consisted of three stories, each of which, abating the thickness of the floors, might be about 18 feet high, and no doubt was partitioned into a great many rooms or apartments. This vessel was doubtless so contrived, as to admit the air and the light on all, though the particular construction of the windows be not mentioned.
