"To gaze into the depths of the sea is, in the imagination, like beholding the vast unknown, and from its most terrible point of view. The submarine gulf is analogous to the realm of night and dreams. There also is sleep, unconsciousness, or at least apparent unconsciousness, of creation. There in the awful silence and darkness, the rude first forms of life, phantomlike, demoniacal, pursue their horrible instincts."
