the Pecten and the Avicula beds being probably identical 
with those which are now worked so extensively at Cleveland. 
In the above section the local names have been retained ; it 
may therefore be necessary to explain that the sulphur rock 
represents a shale formation impregnated to a greater or 
less extent with iron pyrites. 
A boring has been made by Mr. Rowland Winn, about 
half-a-mile to the south of Appleby. The section of strata, 
as shown by the borings, being as follows : —

The Oolitic ironstone (No. 9) of the Esk valley section, 
and which appears in the High Cliff, at Whitby, is, there 
can be little doubt, the grey stone (No. 5) of the above 
Appleby section, which is a continuation of the beds worked 
upon the warren at Scunthorpe, which dip slowly towards 
the sea. 
If we continue our examination southward, we discover 
iron ore workings at Stamford, where the deposits are very 
extensive ; and some smaller workings have been carried on 
near Peterborough. The iron ore deposits of Northamptonshire 
are well known ; and those are believed to be the equivalents 
of the deposits which are now being worked in Lmcolnshire. 
The iron ore which has been discovered at Blenheim, in 
Oxfordshire, has been thought by many to be also a con- 
tinuation of the same series. Mr. E. Hull, of the Geological
