 ish-grey colour. 



1 8. Fine bright yellow sand with a few 

 thin seams of ash-coloured clay. 



17. An imperfectly exhibited series of 

 brown and gi*ey clays, finely laminated with 

 brown and yellow sand, containing subor- 

 dinate green clays and marls. In the upper 

 part the sand predominates. A few small 

 flint pebbles scattered throughout. Fossils. 



16. Brown clay. Numerous Foramini- 

 fera, with Ostrea and Venericardia : — 

 passes upwards into dark greenish marly 

 sand perforated in places by tubes of 

 green-coloured sand containing a few shells 

 and small crystals of selenite. 



15. Light-coloured, compact and fine- 

 grained sandstone. 



14. Imperfectly exhibited. Apparently 

 grey, brown and greenish clays with a few 

 shells — passes upwards into a light yeUow 

 sand.

12. Finely laminated brown clay passing 

 upwards into grey sand, and then into dark 

 grey clay with vegetable impressions. A

 the hottom. 



11. Massive light and dark-coloured 

 slightly calcareous greensandwith small soft 

 white calcareous concretions. In the upper 

 half numerous shells and teeth of fishes. 



10. Laminated grey clay with some beds 

 of calcareous greensand, a few layers of 

 ironsand, and one or two beds of lignite 

 about one or two feet thick. A strong 

 ferruginous spring issues from the junction 

 with 1 1 , converting part of the beach into 

 an ironstone conglomerate. .' A few peb- 

 bles. Passes into 11. 



9. Calcareous clayey green and iron- 

 sand, with numerous shells. Upper part 

 greensand only, with only one seam of 

 shells. Shells grouped in genera. 



8. Alternating beds of greensand and
