A man may go south, and, stumbling over a bone, may meditate upon it till he has found a new starting-point for anatomy; or eastward, and discover a new key to language telling a new story of races; or he may head an expedition that opens new continental pathways, get himself maimed in body, and go through a whole heroic poem of resolve and endurance; and at the end of a few months he may come back to find his neighbors grumbling at the same parish grievance as before, or to see the same elderly gentleman treading the pavement in discourse with himself, shaking his head after the same percussive butcher's boy, and pausing at the same shop-window to look at the same prints.
