But imagine an animal of the lizard species, one hundred and twenty feet long--imagine such a monster--the existence of which is now proved beyond a cavil, by the remains, deeply imbedded in the hard blue lias rocks, and which remains are now in our possession. What a terrific monster it must have been! We look with horror at an alligator of twenty or thirty feet, but imagine an animal of that species extending his huge bulk to one hundred and twenty feet. Were they all destroyed when the waters were separated from the hand, or did they gradually become extinct when the earth was no longer a suitable habitation for them, and no longer congenial to those properties with which they had been endowed when ordered into existence by the Almighty power? The description of the Behemoth, by Job, has long been a puzzle to the learned; we have no animal of the present time winch will answer to it, but in many points, this description will answer to what may be supposed would be the appearance, the muscular power, and the habits of this huge denizen of a former world. "His force is in the navel of his belly. He moveth his tail like a cedar. His bones are as strong pieces of brass. His bones are like bars of iron. He lieth under the shady trees in the covert of the reeds and fens. The shady trees cover him with their shadow. The willows of the brook compass him about." It may be a matter of deep surmise, whether all animals were created as we now find them, that is, whether the first creation was final--or how far the unerring hand has permitted a change to take place in the forms and properties of animals, so as to adapt them to their peculiar situations. I would say, whether the Almighty may not have allowed the principle of vitality and life to assume, at various epochs, the form and attributes most congenial to the situation, either by new formation or by change.
