Mr. Stoddart is certainly rather bold, when he states that this Crag 

 is of the same age as the Chillesford Clay. 



There is no Eed Crag in the section at Bramerton. The relations 

 of the Norwich to the Red Crag have never been seen in section. 

 By some authorities they are considered to be synchronous deposits. 

 Mr, Stoddart is so well known for his successful geological work in the 

 Bristol district, that we regret he did not devote a little more time 

 to the Geology of Norfolk, and look up the literature, before at- 

 tempting to write a paper on the subject. 



Mr. Adolph Leipner gives an account of some of the Carboniferous 

 Corals in the Museum of the Bristol Philosophical Institution, 

 which he hopes to complete and bring before a future meeting of 

 the Geological Section of the Society. 



Number 9 contains : — (1.) Some Notes on the late Movements of 

 the Somersetshire Coast, by Mr. F. C. Ravis. These notes form a 

 supplement to a paper he communicated to the Society about three 

 years ago. He prefaces them with some remarks on the Trap and 

 Mountain Limestone of Woodspring Hill, considering that the in- 

 jection of the trap was prior to the movement that caused the 

 inclination of the beds, because in general outline it appears to con- 

 form itself to that inclination : he thinks it probably contemporaneous 

 with the Limestone. 



Mr. Eavis then proceeds to describe the raised beach of Wood- 

 spring. This evidence of upheaval furnishes strong proof of the en- 

 croachment of the sea, for a twenty feet rise of the land with a 

 shelving beach would be equivalent to a considerable horizontal dis- 

 tance. At present the waves dash against the rocks immediately 

 beneath the old beach.^ 



Ancient Sand hills or Dunes, some contemporary with, others 

 from their gTeater elevation of earlier date than these beaches, are 

 well seen on the northern slope of Worle Hill. Remains of Dunes 

 occur above the raised beach of Birnbeck Cove,^ which beach, from 

 its height above the sea, may probably be of the same age as that at 

 "Woodspring. 



Brean Down exhibits on its northern side at least two tiers of 

 sandy accumulations, at similar heights to the terraces in Sand 

 Bay. The heights of these Dunes above the mean sea-level 

 range to 150 feet. 



Brent Knoll, an isolated outlier of Inferior Oolite, about 500 feet 

 above the sea-level, contains from fifteen to twenty parallel terraces 

 arranged like the seats in an amphitheatre, varying in height from 

 one to five feet, in breadth from one to two feet. They occur at 

 elevations up to 400 feet. These are regarded by Mr. Ravis as due 

 to the action of the sea, and he remarks that they may possibly be 

 contemporaneous in formation with the highest and oldest portions
