Whether we like or dislike this realism, we must allow for it in forming our judgment on these volumes, nor must we treat as final and approved opinions what are often the mere spontaneous suggestions and first thoughts of the mind, the oscillations through which it settles down to rest.

Nor is there the slightest movement to be felt; yet, in the estuary of the Neuse, the current is always strong enough, to cause a marked oscillation to any vessel.
