MESSRS. S. S. BTJCKMAN AND E. WILSON [Nov. 1 896. 



III. The Sections and their Interpretation. 



The sections to be described are taken in the following order : 

 first, from west to east as nearly as may be ; secondly, from 

 Dundry church in a direction south-east by south ; thirdly, from 

 the church in a south-easterly traverse. 



The first section to be noticed is situated towards the north- 

 western corner of the hill in the road-cutting leading from just 

 west of ' The Grove ' to Castle Farm. This section shows only a 

 few feet of rocks, mostly belonging to the hemerse Sonninice-discitce l 

 capped directly by ' top beds.' Most of the other details are the 

 result of special excavations. 2

2 [Since this was written a considerable amount of quarrying has been done 

 here, so that the section is greatly improved. We have been able to add a few 

 details in consequence. — Aug. 31st, 1896.]

 shown by the hemeral names at the left hand, marking the last deposit of 

 the date to which they belong.
