X. — On the Permian Beds of the North- West of England, 

 By Edward W. Binney, F.G.S. 



[Read March 20th, 1855.] 



My observations on these strata will be confined to such 

 sections as I have met with in the counties of Lancaster, 

 Chester, Cumberland, Westmoreland, and York. 



The permian beds, as is well known, constitute the highest 

 portion of the palaeozoic rocks, comprising that part of the 

 earth's crust which lies between the carboniferous formation 

 and the trias, and were first named by Sir Roderick Impey 

 Murchison after a province in Russia, Perm, where they are 

 met with on a grand scale. Long before the date of Sir 

 Roderick's work on Russia, however, Professor Sedgwick had 

 most ably and carefully described these deposits, and shewn 

 their true relation to the underlying carboniferous and over- 

 lying new red sandstone groups, in his admirable paper on 

 the Magnesian Limestone of the North of England, published 

 in vol. in. (2nd series) of the Transactions of the Geolo- 

 gical Society. The same author has also contributed other 

 valuable information on the permian beds of the north-west of 

 England, contained in several papers published by the Geo- 

 logical Society.*

 London, and vol. VIII., page 36, of the same society's Quarterly Journal.
