This constant supply of heat and of cold is effected, as is wellknown, through the agency of currents. The latter are by nomeans an exceptional phenomenon confined to certain parts ofthe ocean. Varying in volume and velocity until they attainthe proportions of gigantic rivers flowing at a rate of severalmiles an hour, they occupy every part of the ocean, no part ofwhich can be said to be in a condition of absolute rest. Com-bined together they form, like the currents in the atmosphere,and in intimate association with the latter, a complete system ofcirculation, by which the physical and chemical equilibrium ofthe ocean is maintained. From the prinoipal storehouse of heatin the tropics, warm currents proceed toward
