Murchisomi^ Carr., and Retiolites Oeinitzianus, Barr. Above this 

 the stream-course is cut for a distance of two chains through the 

 Browgill Beds, and as the passage of these into the Skolgill Beds 

 below is seen beneath a small cascade, the whole of the Browgill 

 Beds are developed in this section, and a nearly continuous section 

 is displayed, the beds dipping quite regularly to the S.8.E. at an 

 angle of about 60°. Just above the cascade which falls over the 

 Coniston Limestone, a tributary enters Stockdale Beck from the 

 north-east ; this is Browgill, and the same stream is refeiTed to by 

 Professor Sedgwick under the name of Iron Crow Gill, and by Profs. 

 Harkness and Nicholson under that of Arncoslde Beck. The lowest 

 twenty chains of the gill are hollowed in the beds of the Coniston- 

 Limestone series ; but at a point a short distance above the 1000-foot 

 contour-line a fault runs diagonally across the stream with a 

 downthrow to the east, which brings the Stockdale Shales against the

Coniston-Limestone Series, and the former beds are traceable for 

 some distance up the stream, which here runs along the strike. As 

 at Skelgill, the Coniston-Limestone Series is seen on the north-west 

 bank, which is a dip-slope, and a steep scarp sometimes rising into 

 precipitous cliffs forms the south-east (left) bank. The lower portion 

 of this is occupied by the Skelgill Beds, whilst the upper portion
