LULWQBTH COVE. 383 



of the Wealden. The headland at the entrance 

 of the cove, consists of contorted Purbeck beds, 

 resting on the Portland oolite, of which large 

 masses project on the shore. The appearance of 

 the undulated layers of Purbeck limestone, is 

 very striking in the weathered portions of the 

 cliff, from the intermediate clays having been 

 worn away, and the bands of stone left prominent. 

 The blocks on the right, in the foreground, are 

 of Purbeck limestone, and extend towards those 

 that form the opposite bar. 



Dr. Fitton, with characteristic accuracy and 

 minuteness of detail, has given measurements of 

 the spaces occupied by the different groups of 

 strata below the chalk in Lulworth Cove. The 

 firestone and gait are about 150 feet; the Wealden 

 beds, 600 feet ; the Purbeck, 450 feet ; and the 

 Portland, 240 feet. The fossils here met with are 

 lignite, and a few paludinae and nniones, in the 

 Wealden ; and in the Purbeck, shells of the same 

 genera occur in layers, and mussel-shells abun- 

 dantly in a coarse green sand-rock, as at Durlstone 

 Head. 



Fossil trees. — Seams of lignite are numerous in 

 the Wealden sands and clays, as in Swanage Bay, 

 and in Brook Bay, in the Isle of Wight. In the 

 Portland strata, a little way to the eastward, are
