The successive series of stratified formations are piled on one another, almost like courses of masonry.

The field of the Geologist's inquiry is the Globe itself, ... [and] it is his study to decipher the monuments of the mighty revolutions and convulsions it has suffered.

Geology holds the keys of one of the kingdoms of nature; and it cannot be said that a science which extends our Knowledge, and by consequence our Power, over a third part of nature, holds a low place among intellectual employments.

The days of the Mosaic creation are not to be strictly construed as implying the same length of time which is at present occupied by a single revolution of our globe, but PERIODS of a much longer extent.

The human mind has a natural tendency to explore what has passed in distant ages in scenes with which it is familiar: hence the taste for National and Local Antiquities. Geology gratifies a larger taste of this kind; it inquires into what may appropriately be termed the Antiquities of the Globe itself, and collects and deciphers what may be considered as the monuments and medals of its remoter eras.

To the mind which looks not to general results in the economy of Nature, the earth may seem to present a scene of perpetual warfare, and incessant carnage: but the more enlarged view, while it regards individuals in their conjoint relations to the general benefit of their own species, and that of other species with which they are associated in the great family of Nature, resolves each apparent case of individual evil, into an example of subserviency to universal good.

Thus the great drama of universal life is perpetually sustained; and though the individual actors undergo continual change, the same parts are ever filled by another and another generation; renewing the face of the earth, and the bosom of the deep, with endless successions of life and happiness.
