and the little hamlet of Southern-down perched on the high cliffs 

 with its fine sea-ward expanse was reached. The remaining 

 portion of a magnificently fine day was spent with our cicerone, 

 Mr. Moore, in unravelling the geological problems which there 

 abound. The members were taken by that gentleman to the 

 " Sutton Stone" beds, which make their first appearance between 

 the mouth of the Ogmore and Southern-down. Here was seen a 

 rugged coastline of Carboniferous Limestone, with numerous sea- 

 polished Producti, Spirifers, and C'orals of that age. Eesting 

 unconformably on this ancient Limestone are thick-bedded Con- 

 glomerates, in which are numerous organic remains, consisting of 

 several species of Corals, Pectens, Ostrcea, Cypricardia, Discina, 

 &'C., which were stated to be all new to science. Above the 

 " Sutton Stone" proper was finely displayed along the coast 

 section to the East a great thickness of thinly bedded stratified 

 Conglomerates, but rarely containing organisms. Although 

 lithologically so unlike what has usually been known as Lower 

 Lias, Mr. Moore stated tliat these beds were really only abnormal 

 conditions of the Lima series of that formation, and therefore of 

 the same age as the Liassic beds of Weston and Twerton, near 

 Bath. Passing from this point to the beds under Southern-down, 

 the Lima beds in their usual condition are exposed, contain- 

 ing Ammonites Bucklandi, A. angulatus, and Lima gigantea, 

 characteristic shells of that formation. To the Eastward of the 

 point under Dunraven Castle, the "Sutton Stone" is again 

 brought up, resting as before on Carboniferous Limestone, and 

 ill beds immediately above Mr. Moore again pointed out the 

 presence of a Liassic fauna. The abnormal condition of the 

 Secondary beds where they come in contact with the Carbon- 

 iferous Limestones on the Mendips was alluded to, more 

 particularly a section at Shepton Mallet, where Liassic beds, 

 identical in lithological structure with those of the "Sutton 

 Stone," are to be found ; and as there were organic remains of 

 the same species common to the two distiicts, the Shepton beds
