260 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Feb. 5, 



and as to the true geological character of the beds of which it 

 consists. 



During the progress of the excavation of these cuttings, Mr. 

 Bentley and I had the advantage of traversing them more than once 

 in the instructive company of Professor Morris ; and I am fortunate 

 in possessing, and in being enabled to exhibit a selection from, 

 fossils gathered on those occasions by Mr. Bentley and myself. 



Casewick Cutting. 



The most southerly of these cuttings is at Casewick, about three 

 miles to the south-east of Stamford. The upper part of the section 

 consists of 8 feet of Quaternary Drift beds ; between which and the 

 Secondary beds, is intercalated, for the space of about 30 yards, a 

 freshwater deposit : these are of sufficient interest in themselves, 

 but are foreign to my subject. Professor Morris describes the 

 uppermost Secondary bed in this cutting as being Oxford Clay : he 

 then gives Kelloway Rock, and then Oxford Clay again : the lowest 

 bed of the section and the floor of the cutting consist of Cornbrash. 



I have characteristic fossils from each of the beds of this section, 

 including — Ammonites Herveyi, A. biplecc, and A. Goiverianus, from 

 the Oxford Clay ; Grryphcea bilobata, in every stage of growth, and 

 the very characteristic Avicula expansa, from the Kelloway Bock ; 

 and two fair specimens of the rare and peculiar Terebratula Bentley i 

 from the Cornbrash.
