Such are the mutations constantly occurring in nature. 

 Thus calcareous matter, at first hard and crystalline, by 

 degrees softens and becomes almost milky, under the 

 influence of the never-ending succession of salt spray and 

 aqueous vapour, to be finally swept from a thousand 

 sources into the ocean, to fulfil another term in existence, 

 and to be once more deposited or organised in new forms. 

 To the south east of the little island, and nearly in the 

 line of dip, I obtained additional sections, exhibiting an 

 immense thickness of carbonaceous deposits, which only 

 in a few insignificant instances, however, reach the con- 

 dition of coal. 



Immediately opposite the little island there has been a

The strata are here interrupted ; and the banks recede 

 in low undulating sandy hills through which two creeks 

 issue to the sea. 



Further on, in the direction of the extreme point of the 

 Whale's Head, the stratified rocks recur dipping to the 

 east, and afibrding the following section in ascending 

 order : —
