of Wealden, tiz. at Balcombe, 

 and Hayward's Heath. 



Geological mutations. — 

 The present distribution of the 

 strata, as shown by the pre- 

 ceding observations, appears to 

 admit of the following explana- 

 tion. Assuming the original de- 

 position of the strata to have 

 taken place as in lign. 2 — 

 the wealden resting on the 

 oolite, the chalk on the weal- 

 den, and the tertiary on the 

 chalk — the surface of the 

 country must have consisted of 

 the same strata as those of the 

 immediate vicinity of London. 

 Now if any elevatory force 

 acted from beneath, in the di- 

 rection of the arrow, B, the 

 entire scries would be broken 

 through, and the chalk with 

 the tertiary it supported thrown 

 into highly inclined positions 

 to the north and south ; and if 

 a similar disturbance took place 

 along the area now occupied
