The probable position of the base of the Lower Permian is 2,000 feet to 

 the north, giving a dip to the south of the surface of the Coal-measures of 

 10 deg. The water was believed by the late Mr. Binney, F.R.S., to be 

 derived in these wells from the Lower Permian sandstones. Westwards 

 the red marls with fossiltferous limestones are worked at Astley and Bed- 

 ford Leigh. At Worsley this series reaches a thickness of 131 feet, 

 and contains 52 thin beds of limestone. Eastwards the Lower Permian 

 sandstone increases in importance, and is worked as moulding sand at 

 CoUyhurst.
