“ Notes on a Bore through Triassic and Permian Strata, 
lately made at Openshaw/’ by E. W. Binney, Y.P., 
&c. 
For many years attention has been given by local 
geologists to the district lying between the Manchester 
coalfield and that of Ashton-under-Lyne and Oldham. 
The first authors that have treated on it were probably 
Messrs. Conybeare and Phillips, in their Outlines published 
in 1822. Mr. James Heywood, F.RS., in a paper published 
in Yol. YI. (2nd series) of the Society’s Memoirs, also 
noticed it. In a communication of my own, published in 
the 1st Yol. of the Transactions of the Manchester 
Geological Society, a horizontal section is given of the 
country between Manchester and Waterhouses, showing 
one great fault as then known. Afterwards, in Yol. XII. 
(2nd series) of our Memoirs, evidence is given of another 
fault at Medlock Yale, and lately in Part YI., Yol. XY, of 
the Transactions of the Manchester Geological Society, 
Messrs. Bradbury and Atherton have shown a third fault 
at Openshaw. As the district is thickly covered by drift 
deposits, and few natural sections are exposed, we have to 
wait till evidence is afforded by borings and sinkings. In 
several papers by me printed in the Memoirs, information 
has been given as it was met with, and as Mr. John 
Bradbury’s boring is one of the most valuable, I wish to 
add it to my other communications on the subject, in order 
to make them more complete. 
Mr. Bradbury’s labours have shown the Permian sand- 
stone, the one so well exposed at Yauxhall, in our city, to 
be of greater thickness than hitherto proved in the district, 
and as this deposit is a most formidable difficulty in sinking 
to the underlying coal seams, it is desirable that all infor- 
mation respecting it should be given to the public. 
The bore was made near to the Ashton canal in Open 
shaw, and adjoining the boundary of that township with
