VOYAGE ROUND THE ISLE OF WIGHT. 339 



freshwater strata on the northern extremity of 

 Whitecliff Bay (see p. 127) next appear, and a 

 good view is soon obtained of the bay, bounded 

 on the south by the magnificent chalk cliffs of the 

 Culvers. 



On reaching the extremity of Whitecliff Bay, 

 the vertical section of the highly inclined chalk 

 strata, which forms the eastern promontory of 

 the Island, is finely displayed (see PL XV.). The 

 dip of the strata, varying from 50° to 70° towards 

 the north, is clearly marked by the layers of flint 

 nodules, which are distinguishable a quarter of a 

 mile from the shore. Culver Cliffs, which the 

 reader will remember, are the eastern termination 

 of Bembridge Downs (see lign. 8, p. 126), are be- 

 tween 300 and 400 feet high, and about a quarter 

 of a mile in breadth. When off the promontory, 

 a very interesting geological view is obtained ; 

 at one glance we see the nearly vertical chalk, 

 bounded on the right {north) by the eocene strata 

 of Whitecliff, and on the left (south) by the green- 

 sand of Redcliff. 



Upon doubling the headland, we enter Sandown 

 .Bay (see the section, lign. 9, p. 134) ; the lower 

 chalk, firestone, gait, and greensand, appearing in 

 succession, like sloping bands of yellowish white, 

 green, blue, and deep red; the latter denoting the
