These strata consist of the accumulated exuviae os shellfish, the animals perished age aster age, but their shells remained, and in progression of time produced the amazing quantities of lime-stone which almost cover the earth. Other marine animals called coralloids raised walls arid even mountains by the congeries of their calcareous habitations; these perpendicular coralline rocks make some parts of the Southern Ocean highly dangerous, as appears in the journals of Capt. Cook. From contemplating the immense strata of lime-stone, both in respect to their extent and thickness, formed from these shells of animals, philosophers have been led to conclude, that much of the water of the sea has been converted into calcareous earth by passing through their organs of digestion.
