riod, but owing to the absence of coral from the northern, we 

 have evidence only with regard to the more southern. 



Guam, according to Quoy and Gayraard, has coral rock upon 

 its hills more than six hundred feet (one hundred toises) above 

 the sea. 



Rota, the next island north, afforded these authors similar 

 facts, indicating the same amount of elevation. 



n. Pelews, and neighboring Islands. — The island Feis, three 

 hundred miles southwest of Guam, is stated by Darwin, on the 

 authority of Lutke, to be of coral, and ninety feet high. Mack- 

 enzie Island, seventy-five miles south of Feis, is a low atoll, 

 as ascertained by the Expedition. No evidences of elevation 

 are known to occur at the Pelews. 



o. Melanesian Islands. — Among the New Hebrides, New 

 Caledonia, Salomon Islands, the evidences of elevation have 

 not yet been examined.
