manner in which a small section of lower rocks disappears at a little 

 distance to the north-east of the hill. 



This section extends from the arenaceous into the sub-nummulitie 

 group, and shows but feeble representatives of the intermediate beds 

 which enter so largely into the structure of the country hitherto des- 

 cribed. It is as follows : — 



Descending order,
