 several ledges are seen, which mark so many levels at which the w r aves of 

 the sea may be supposed to have encroached for a long period. At a 

 still greater height, immediately above the top of this range, are three 

 much smaller cliffs, each about 4 feet high, with as many intervening 

 terraces, which are continued so as to sweep in a semicircular form 

 round an adjoining coomb, like those in Sicily before described (p. 76).
