The following diagram (fig. 50) shows the appearance of 

 the coast, and the localities mentioned in the preceding mea- 

 surement. 



Coast from the Chalk to the Red Rock, Studland Bay. 



1, Chalk. 2, Sand. 3, Conglomerate, based on arched iron stone. 4, Boat-house.

 beds.

 openings, which must have been produced by a rent of great
