344 GEOLOGY OF THE ISLE OF WIGHT. 



The vertical strata of Alum Bay (p. 146), and the 

 freshwater series at Headon Hill (p. 151), are now 

 on our right ; and we perceive that the structure 

 of this north-western extremity of the Island, is 

 the counterpart of the north-eastern promontory 

 at Culver Cliff and Whitecliff Bay, which we 

 sailed by in the earlier part of our voyage. Col- 

 well and Thorness Bays are next passed, and we 

 land at Yarmouth to prepare for our excursion to 

 the Dorsetshire coast.
