Hence the entire remaining portion of the sphere beneath the crust could not have contributed sufficient contraction to have caused the requisite compression, even under circumstances more favourable than are likely to be true regarding the increase of volume due to the presence of the water. From this result we feel obliged to abandon the hypo- thesis that the existing inequalities can be accounted for by the extravasation of the water, now composing the oceans, from beneath the crust. There is one other cause which must necessarily have dis- turbed the equilibrium of the crust during the lapse of ages, and that is the diminution of the oblateness of the spheroid. The friction of the tides, whether oceanic or bodily, must neces- sarily have diminished the rotational velocity, and lessened the oblateness. The parts of the crust about the poles will con- sequently have been subjected to stretching, and those about the equator to compression. There is however no apparent reason immediately to connect the inequalities with this cause, for the continents do not occupy an equatorial belt, as they would do under this hypothesis, nor have the polar regions been free from the compression which all continental areas have experienced. 1 See p. 167.
