Science; Physics; Sciences; Physique. 168 THE ORIGIN OF ' , :L of what is constantly ocoiirring all over tho Atlantic and Pacific Oceans. Ho has a theory of a general oceanic circula- tion which he is endeavouring to have accepted as an established doctrine of science, viz. : That there is a continuous under- current of cold water throughout the oceans, Irom the Poles to the Equator, and a surface current of warm water from tho Equator back again ; thereby equalizing tho temperature all over tho world, and bringing every part of the waters to tho surface, to purify and make it fit for the preservation of animal life in the deepest sea beds. Ho has made his observations from a series of deep sea soundings, in which he has found that the sea bottom, even at the depth of two and tlu'ce miles, has averaged thirty degrees by Farenheit's Thermometer. His opinion is, therefore, that tho water could not be so cold unless it came from the Polar regions, inasmuch as cold water always falls to the bottom, while warm water floats on tiie surface. In order to. illustrate his assertions he makes an experiment with a glass trough, six feet long, one foot deep, and one inch wide. This is filled with water. At the surfase of one end ho fixes a piece of ice, to represent the i^ole, and at the other he applies a bar of heated metal, for the equator. Dropping some blue colouring matter into tlie polar end, and some red at tho equator^ a circulation is at once seen to be established. The cold blue water sinks, then creeps along the bottom till it reaches the heated end, is there warmed, rises to the surface, and returns to the pole again; while the reddened water flows along the surface to the pole, sinks and returns just as it is expected to do. But this is not a fiiir illustration, because what would occur in six feet of water, would not well apply to a distaucQ o
