Several deductions are at once obvious : — 



1. That the elevations have taken place in aJl parts of the 

 ocean. 



2. That they have in some instances affected single islands, 

 and not those adjoining. Metia is 250 feet high, and yet the 

 other Paumotus in that part of the archipelago, and also the 

 Tahitian Islands, have been but little, or not at all, elevated. 



3. That the amount is often very unequal in adjacent 

 islands. 



4. That in a few instances the change has been experienced 

 by a whole group or chain of islands. The Gilbert Group is 

 an instance, and the rise appears to increase from the south- 

 ernmost island to Apaiang, and then to diminish again to the 

 other extremity. 



The Feejees may be an example of a rise at the west side of 

 a group, and possibly a subsidence on the east, while a little 

 farther east, the Tonga Islands constitute another extended
