Vol. 58. ] PERMIAN, AND TRIASSIC OF THE ISLE OF MAN. 649 
The red sandstones, underneath the Glacial Drift, are identical in 
their physical characters with the St. Bees Sandstone in Cumber- 
land, and are of Triassic age. They dip at an angle of 8°. 
The details of this portion of the section are to be found in the 
paper read before the Manchester Geological Society, already quoted, 
and also in vol. xxiii, pt. 1 of that Society’s Transactions, and there- 
fore need not be repeated here. 
The purple, red, and grey shales, marls, and marlstones, below 
the Triassic strata, are very much sheared and crushed. At depths 
respectively of 627 and 657 feet from the surface, the boring-tool 
passed through a conglomerate-breccia, indistinguishable from some 
of the Permian Brockrams, to which they were referred in the above- 
quoted paper. The specimens, however, which I have examined in the 
Museum at Jermyn Street (by the kindness of Mr. Lamplugh) prove 
that the strata, both above and below, are of Lower Carboniferous age. 
They are identical with the type of Yoredale rocks which surrounds 
the massif of the Lake District and ranges far over the adjacent parts 
of Yorkshire. I can only account for the breccias in these rocks by 
the hypothesis that they occupy lines of fault, filled with the crushed 
adjacent rocks of Yoredale age, from the break-up of which the 
Brockrams elsewhere have been largely constituted. These Yoredale 
rocks dip at an angle of 35°, at points respectively of 611 feet and 
686 feet below the surface. 
The thickly-bedded limestones beneath belong to the Carboniferous 
Limestone, and have been more or less hematitized in irregular 
patches.
