30 MR. E. W. BINNEY ON THE 



In my first paper, before alluded to, at p. 217 a short 

 notice is given of a very interesting boring made some 

 years ago at the bleach- works of Mr. Tait at Heaton 

 Mersey, which proved that the permian beds there were 

 of great thickness. Since that time, the lower new red 

 sandstone has been exposed by Mr. Howard near the rail- 

 way station at Heaton Norris, for the purpose of being 

 quarried for moulding sand, like that at CoUyhurst near 

 Manchester ; and the permian marls have been seen lying 

 upon it, and succeeded in their turn by the beach beds 

 of Mr. Hull, and then the pebble-beds of the trias up to 

 Heaton Mersey Mill. 



In my former paper, there was given the section of the 

 bore at the last-named place, which was as follows : — 



feet. 

 Sand and grayel a few feet. 



Trias 45 



E«d and variegated beds of marl containing limestones 129 



Lower new red sandstone (CoUyhurst), proved 402 



576 



This section is shown on the *banks of the Mersey. 

 Near the position of the bore marked A in the wood- 

 cut, and for about 300 yards towards Stockport, the trias 

 cannot be seen, owing to the covering of valley-gravel. 

 When it makes its appearance, it is as a bright-red and 

 fine-grained sandstone containing pebbles ; then come beds 

 of red sandstone, which Mr. Hull considers to be like his 

 pebble-beds. These are succeeded by some singular coarse 

 beds containing angular pieces of quartz, which the same 

 gentleman took to be old beach-beds. They dip to the 

 S.W., at an angle of 12°. 



Next appear red and variegated marls, which are ex- 

 posed in the vacant piece of ground behind Well Lane, 

 opposite Orrell's Mill. Twenty feet in thickness are seen ; 

 and they dip to the S.W., at an angle of 25°. Although 

 examined with considerable care, no fossil shells were found
