1. Notes on the Lo wee-Lias Beds o/ Bristol. 

 By W. W. Stoddart, Esq., F.G.S. 



The occurrence of beds in the Bristol district corresponding to the 

 Sutton beds of Glamorganshire has been thought worth noting. 



In this locality the sequence of the different groups of strata is 

 so perfect that the position of any one of them becomes almost a 

 matter of certainty. 



In many places the beds are apparently so bare of organic remains, 

 that the collector is at once discouraged. The very horizontality of 

 the beds themselves is frequently an obstacle, from the great distance 

 to be walked over before a change of zone takes place. 



The line of section in the following sketch (fig. 1) runs from a 

 quarry (N'o. 1) north of the Orphan House on Ashley Down, across 

 Montpelier, to Gotham Hill. 



As shown in the figure, three quarries, now fortunately opened, 

 explain the whole series of beds contained in the section. 



It will be seen that the series extends from the base of the zone 

 of Ammonites Turneri down to the Rhsetic beds. 



All of them dip 8°, to the north-east. This small angle makes the 

 beds appear nearly horizontal, and at first sight makes their order 

 very puzzling.
