be noticed that although the excavation of the sea-bottom to its present 

 depth below the zero plane, corrected for the weight of the ocean, pro- 

 duces no motion in the pole, yet that the depression of a continent down 

 to the zero plane produces a motion of pole equal and opposite to that 

 produced by its elevation. I have calculated the hypothetical effects of 

 the depression of imaginary continents occupying the sites of the present 

 Pacific Ocean, with the following results : —
