The lllagnilude 0f the Ocean.

v a2

A ariHERE are several arbitrary quantities j, which contribute to determine the state of things at the earth’s surface besides those already mentioned. Some of these we shall briefly refer to, without pursuing the subject into detail. We wish not only to show that the properties and processes of vegetable and animal life must be adjusted to each of these quantities in particular, but also to point out how numerous and com- plicated the conditions of the existence of or- ganized beings are ; and we shall thus be led to think less inadequately of the intelligence which has embraced at once, and combined without (ronfusion, all these conditions. We appear thus to be conducted to the conviction not only of design and intention, but of supreme knowledge and wisdom.

One of the quantities which enters into the constitution of the terrestrial system of things is the bulk of the waters of the ocean. The mean depth of the sea, according to the calculations of Laplace, is four or five miles. On this sup- position, the addition to the sea of one-fourth of the existing waters would drown the whole of the globe, except a few chains of mountains.
