PRELIMIXARY XOTE ON UPPER COAL MEASURES IN YORKSHIRE. 
BY H. CULPIN AND G. GRACE, B.SC. 
A cutting made near Cadeby (Conisborough) during the 
construction of the new Dearne Valley Railway has recently 
exposed the base of the Permian Limestone lying on Carbon- 
iferous shales. At a depth of about ten feet below the Permian, 
among dark-coloured shales, is a layer of ironstone, about three 
inches thick, containing shells which have been identified by 
Mr. H. A. Allen, of the Geological Survey, and confirmed by 
Dr. Wheelton Hind, as Anihracomya Phillipsi. 
This is the first time traces of undoubted Upper Coal 
Measures have been found in the county. 
The investigation of the exposure is still in progress, this 
preliminary note being published at the request of Prof. P. F. 
Kendall, so that he may make use of the fact in the report on 
the eastern extension of the Yorkshire Coal-field, which he is 
preparing for the Royal Commission on Coal Supply.
