Abstract
AS Dr. Carpenter explained in his lecture here some short time ago, four-elevenths, or nearly three-fourths of the surface of the earth is covered by sea. The average depth of the ocean is, according to the latest calculations of Mr. Otto Krummell, about 1,877 fathoms, or somewhat over two miles, very nearly the distance from the Royal Institution to the top of Primrose Hill. If we try and project Primrose Hill directly under our feet, keeping the distance the same, we shall form a conception of the mean depth of the sea. The greatest depth known to exist was discovered by the United States ship Tuscarora near the Kurile Islands, in the North-east Pacific. It is 4,655 fathoms, or about five miles and a quarter.
