The Triassic sandstones below the Drift, in this section, are the 
same as those in the preceding section, and dip at an angle of 
7°, as compared with that of 8° at Ballawhane. 
The red sandstones, and marlstones, below the ''riassic sandstone, 
are assigned to the Permian age, because they contain conglomerate- 
breccias, tormed of Yoredale rocks and Carboniferous Limestone, 
embedded in a calcareous paste, and presenting the curious physical 
characters of the Brockrams of Cumberland and the Vale of Eden. 
- They are identical physically with those which are exposed on the 
shore to the north-east’ of Peel, described in the preceding paper 
(p. 637). Here they are of especial interest, because they rest upon 
the Carboniferous rocks from which they have been torn. 
The Yoredale rocks are of the usual Lake-District type, and like 
them are more or less hematitized. They dip at an angle of 30°, 
at depths of 675 and 716 feet from the surface. 
The Carboniferous Limestone below is of the usual crinoidal type, 
and is locally stained red.
