There are very few persons who pursue science with true dignity.

If I am allowed to give a metaphorical allusion to the future state of the blessed, I should imagine it by the orange-grove in that sheltered glen on which the sun is now beginning to shine, and of which the trees are at the same time, loaded with sweet golden fruit and balmy silver flowers. Such objects may well portray a state in which hope and fruition become one eternal feeling.

Geology, perhaps more than any other department of natural philosophy, is a science of contemplation. It requires no experience or complicated apparatus, no minute processes upon the unknown processes of matter. It demands only an enquiring mind and senses alive to the facts almost everywhere presented in nature. And as it may be acquired without much difficulty, so it may be improved without much painful exertion.

The whole language of nature informs us, that in animated beings there is something above our powers of investigation; something which employs, combines, and arranges the gross elements of matter - a spark of celestial fire, by which life is kindled and preserved, and which, if even the instruments it employs are indestructible in their essence, must itself, of necessity, be immortal.
