The beds since exposed extend eastwards, towards the 

 London and North Western Railway, for a distance of 

 about 734 feet, the average dip is about i6 degrees, 

 the maximum inclination being to the S.W., or an angle 

 to the line of railway, the thickness of the beds exposed 

 is not less than 244 feet. They consist of bright purple marls 

 occasionally mottled. 



The most interesting portion of the section discloses

The number IX. limestone is remarkable for containing 

 large patches of nearly pure hematite; on microscopic 

 examination the grey portions of it prove to be wholly 

 made of fragments of Entomostraca and bone, curiously 

 intermingled, and closely mixed up, with the atoms of 

 hematite.
