The author's attention was first directed to these strata by Mr. John 

 Price, of New College, Bristol. They occur immediately south of 

 the narrow belt of carboniferous limestone, which skirts the coast from 

 the Great Ormes Head, eastward, to the Point of Air and the Estuary 

 of the Dee. The belt of limestone is here not above a mile broad, 

 and the strata dip N. or N.E. At the base of the limestone precipices 

 at Craig y Forwyn, is a seam of impure coal about a foot thick, and a 

 thinner layer of bituminous shale with carbonized impressions of Le- 

 pidodendra ? and a leaf-like Poacites. The beds constituting the 

 following section are successively displayed between Llandulas and 

 Garthewin, a distance of nearly six mUes : —

 consisting of " light loam," and the rounded pebbles of
