Whittemore, Arkwright, predict the fusible, hard, and temperable texture of metals, the properties of stone, water, and wood? Do not the lovely attributes of the maiden child predict the refinements and decorations of civil society? Here also we are reminded of the action of man on man. A mind might ponder its thought for ages and not gain so much self-knowledge as the passion of love shall teach it in a day. Who knows himself before he has been thrilled with indignation at an outrage, or has heard an eloquent tongue, or has shared the throb of thousands in a national exultation or alarm?

No man can antedate his experience, or guess what faculty or feeling a new object shall unlock, any more than he can draw to-day the face of a person whom he shall see to-morrow for the first time.
