the specimens of Ch/amys vagans (Sow.) and Rhynchonella 
Bouetz, Davidson, literally encrusted with the foraminifer 
Webbina and species of Stomatopora, Berenicea, small 
oysters and Sespule (thereby indicating very slow accum- 
ulation), and the Fuller’s Earth clays, unfossiliferous 
except for an occasional oyster and specimen of Sezpula 
vertebralis, Sowerby, suggests that the pause in deposition 
here was contemporaneous with the formation of the 
Bath Stone to the north. It is necessary, however, to 
‘set off against this apparently feasible explanation, the fact 
that certain species of ammonites that characterise the 
Fuller’s-Earth Rock of Dorset (a bed that occurs in Dorset 
and in the greater part of Somerset) have been obtained 
also from the Great Oolite of Minchinhampton, which 
brings these two deposits into line. This is a fact that 
cannot be ignored, and therefore the main interest of 
future research attaches to the determination of what 
really happens in the neighbourhood of Bath. It was 
explained that this was a matter that was receiving the 
Lecturer’s attention, but the paucity of satisfactory sections 
in that neighbourhood, combined with the scanty records 
of former observers, renders the investigation difficult. , 
The Cornbrash succeeds the Forest Marble, and ex- 
tends in a continuous belt from the Yorkshire coast at 
Gristhorpe Bay to the Dorset coast, and is succeeded by 
the Oxford Clay that is worked at several places near 
Weymouth for brick-making. 
Near Weymouth the dip of ;the beds swings round 
from east, through north-east, to north, and it is obvious 
that an anticlinal axis passes close to Weymouth and out 
into the channel well south of St. Alban’s Head. There- 
fore on the north side of Weymouth the general dip is 
towards the north, and on the south side towards the 
south. A view of Portland Harbour and the Chesil
