WRIGHT INFERIOR OOLITE.

Avhich forms an immense prominence at the base of the cliff. In 

 consequence of the disintegration of the shaly bed beneath the 

 block-sandstone, there has been a considerable fall from the upper 

 beds, and an extensive waste in that portion of the cliff. In feet, a 

 wide amphitheatre is here excavated, the floor of the terrace 

 being formed by the crystalline Millcporc-rock, upon which large 

 blocks of grey limestone and block-sandstone have fallen, looking 

 like glacial boulders on a raised beach. From these detached masses 

 of grey limestone a good series of oolitic fossils may be obtained. On 

 descending from this thick sandstone bluff, we meet with the upper 

 sandstones of the " Dogger," which, near this point, rise on the shore. 



b. The Do(jij( r. 



No. 1. The " Dogger" rises on the shore to the south of Blue Wick, 

 where it has a considerable thickness; but it becomes gradually 

 thinner as it rises in the cliff. The uppermost bed is a strong 

 sandstone, of a reddish colour ; it is extremely hard, and contains 

 much iron, and has a number of small rounded pebbles disseminated 

 through the bed, which are sometimes in scams. Where the rock 

 is weathered, they project in relief from the surface, and arc well 

 Bees from the shore. This Band-rock appears to be unfossiliferous. 

 It measures about eight feet in thickness. It rests upon, or rather 

 it encloses, a fossiliferous seam, containing all the characteristic 

 fossils of the Dogger, the following list of which is made from speci- 

 mens contained in Mr. Lcckenby's cabinet.
