12 PICTURE OF ORGANIZED NATURE. 



39. The Cordilleras in South America, from Chim- 

 borazo to 8 S.L., elevate themselves from 9851 ft. to 

 11478. Beyond the 8th degree, several summits 

 penetrate into the snow-line, varying in height 

 between 19,000 and 14,000 ft. Many of them are 

 active volcanoes. The Corderillas extend to the 25th 

 degree s. L. Among numerous summits, Descabezado 

 in Chili is particularly remarkable ; its height being, 

 according to Molina, 21,315 ft. 



40. The Peak of Otaheite in the Pacific Ocean, in 

 18 s. L., does not reach the sivow-line ; its height 

 being only 10,230 ft. 



41. Finally, Mount Egmont, in the northern part 

 of New Zealand, is represented in 39 25' s. L. Its 

 height, according to Forster, is 15,315 ft. ; and it 

 penetrates considerably into the snow-line. 



DEPTH OF THE SEA. 



The depth of the sea is opposed to the elevation 

 of the earth. In the air, a limit is placed to organic 

 life by the perpetual snow-line, beyond which it cannot 

 long exist. Whether in the sea, also, there be depths 

 where no creature is able to live, or whether a boun- 

 dary be assigned to organic life within those depths, 

 cannot be ascertained. It however clearly appears,
