DESCRIPTION OF THE COAST. 
perpendicular rocks which rise from Filey brig, under a cover of diluvial 
clay and pebbles, to the summit of Gristhorpe cliff. Under them runs 
a considerable thickness of calcareous grit beds, which above are hard, 
rough, and cherty, but beneath become soft, gray, and argillaceous, 
indicating the change to the Oxford clay. About three quarters of a 
mile from Filey brig, the Oxford clay appears, and soon afterwards 
the sandy and irony Kelloways rock and the argillo-calcareous corn- 
brash beds rise into the cliff.

These will be particularly described, 
when we come to treat of the 
castle-hill at Scarborough. 
Between Gristhorpe and Red cliff, the upper strata have been re- 
moved from the shore, and the wide hollow so produced partly filled by 
diluvium ; but the Kelloways rock and the carbonaceous shale and 
sandstone, still rising northward, allow the oolitic limestone beneath them 
to appear at low-water between a remarkable rock surrounded by the 
sea at high-water and Red cliff. The relative position of the several 
rocks may be gathered from the general section, and the particular 
characters of the carbonaceous sandstones and shales, and the inferior 
oolite, may be understood by consulting the enlarged representation of 
this interesting spot. 
Here in the upper part, above the layer marked h, we observe 
towards Red cliff the same shales and thin sandstones which were
