not be distinguished from the upper permian sandstones of 
the neighbourhood of Dumfries, which he had just returned 
from examining. Now, if they can be proved to overlie 
immediately the coarse grained, false bedded, soft red and 
mottled sandstones of Whiston and Croxteth Park, both the 
latter as well as the former, will have to be classed as permian 
rocks according to the present Geological nomenclature of the 
North West of England ; and he thinks that the new sections 
he now describes at Roach Bridge, Cockersand Abbey, and 
Robshaw Point, tend to confirm this view. 
In all the quarries of Lancashire where the trias sandstones 
have been wrought, the author has never seen so hard and 
thin bedded a stone as that found at Knowsley. It was 
formerly used for paving sets in Liverpool, and large quanti- 
ties of it were broken for road metal purposes, for which he 
never knew a trias rock used. Some of its beds also afforded 
fined grained flags, with faces as smooth as any permian 
sandstone he had even seen in the neighbourhood of Dum- 
fries. A good example of pebble beds is seen at Kirkby 
Rough ; but this rock bears no resemblance to the stone at 
Knowsley quarry, and the two stones cannot well be classed 
as the same from their characters.
