UPPER PORTION OP THE COAL-MEASURES. 



313 



A bed reached at a depth of 1320 feet from the surface, and 

 72 feet thick, may belong to the Keele Group ; but I am rather 

 inclined to regard it as referable to the Newcastle-under-Lyme 

 Group. The plants from this bed, though all but one occur in 

 the Upper Coal -Measures, are commoner in the Middle Coal- 

 Measures, and there is no characteristic Upper Coal-Measure plant 

 found among them. 



The supposed unconformity, which brings the Newcastle-under- 

 Lyme Group (?) against the Middle Coal-Measures in this section, is 

 much more probably the result of a fault : since, with the exception 

 of this possible unconformity, the Keele Group has been found 

 always conformable to the underlying Coal-Measures.

 Colliery, Great Barr, near Birmingham. [For condensed section, see 

 Trans. Boy. Soc. Edin. vol. xxxv (1888) p. 318. The Upper Coal-Measures 

 probably end at a depth of about 1233 feet.]
