by three ranges of hills connected by two plains. — 1 . The most western 

 ridge is that of the great oolite, the highest part of which is 813 feet 

 above the sea. It is separated, by the plain of the Oxford clay, from 

 —2. The range of the coral-rag ; which again is detached, by the 

 valley and plain of the Kimmeridge-clay and gault, from — 3. The 

 range of Chalk-hills. 



The author describes in succession the several members of the se- 

 ries above mentioned : giving for each stratum an account of the 

 range and boundaries, a general type of the succession and propor- 

 tion of the component beds, with a detail of the physical characters 

 and local peculiarities and names, and an enumeration of the orga- 

 nized remains, detailing the species of the fossils, with their localities 

 and references to published figures. These copious details do not 

 admit of abridgement. 



The paper is illustrated by the corresponding sheets of the Ordnance- 

 map, so far as they have been hitherto engraved, coloured geologi- 

 cally ; and by several sections explanatory of the succession of the 

 strata, and of the forms of the surface.
