as the wind. The cause of this connection be tween the wind and water seems almost to speak for itself; from the vernal to the autumnal equinox, that is, during the S. W. monsoon, the lower current of air, and also the waters of the southern hemisphere are put in motion, to fill up a vacuity, caused by the rarefaction of the atmosphere, and the evaporation of the waters of the northern atmosphere, both of which are increased near the land. And on the contrary, from the autumnal to the vernal equinox, when the sun is on his return to the tropic of Capricorn, the atmosphere being rarified over every part of the southern hemisphere, the wind and water operated on by the same causes, will move in a contrary direction from the N. E. to the S. W. As a confirmation of this hypothesis, currents are always found in proportion to the strength of wind, and both the winds and currents grow weaker towards each equinox." The currents running to the northward in the Indian ocean, between the vernal and autumnal equinoxes, may also also be strengthened by the fusion of the southern polar ices, during the southern summer solstice; and this will operate, though in a diminishing ratio, until the sun reaches the equator on his return to the southern hemisphere.
