The influence of the temperature of the Gulf-stream upon animal life in the ocean is very curious. The whale so sedulously shuns its warm waters, as almost to indicate their track by its absence ; while yet abundantly found on each side of it. The physical reasons are doubtless the same which prevent this great marine mammal from ever crossing the equator from one hemisphere to the other — a fact now well ascertained.
