117 



this white oolite with Isastrcea, Ceromya, Nerincea, &c., and its 

 marly partings' is usually a dark clay, 4 feet thick, with carbonized 

 wood (jet). On this rests a variable series of shelly limestones and 

 soft argillaceous beds, varying much and within short distances, 

 being sometimes wholly calcareous and of the shelly character called 

 " rag." Cornbrash lies above, with the usual fossils, Nucleolites, 

 Holeetypus, Avicula echinata, Pholadomya, &c. 



The succession of the beds between the Cornbrash and Oolite is 

 well seen at the Kirtlington Station, north of Oxford, and in the 

 neighbouring quarries.
