Nature is beautiful, and you are in her bosom. That voice of comfort which speaks in the breezes of morning, may visit your mind, that the delightful influences which the green leaves, the blue sky, the moonbeams and clouds of the evening diffuse over the universe, may in their powers of soul-healing, visit your day visions, is my desire and hope.

Consistency in opinion is the slow poison of intellectual life, the destroyer of its vividness and energy.

Nothing tends so much to the advancement of knowledge as the application of a new instrument. The native intellectual powers of men in different times are not so much the causes of the different success of their labours, as the peculiar nature of the means and artificial resources in their possession.

To me there never has been a higher source of honour or distinction than that connected with advances in science. I have not possessed enough of the eagle in my character to make a direct flight to the loftiest altitudes in the social world; and I certainly never endeavored to reach those heights by using the creeping powers of the reptile, who in ascending, generally chooses the dirtiest path, because it is the easiest.

By science calmed, over the peaceful soul, Bright with eternal Wisdom's lucid ray, Peace, meek of eye, extends her soft control, And drives the puny Passions far away.
