The Permian rocks occupy a considerable tract to the 
north from Ashow to Baddesley Endsor, and repose on 
the coal measures. Their thickness has been estimated 
at nearly 2,000 feet. They are composed for the most 
part of alternating beds of white, purple, and red sand- 
stone and marls; these sandstones sometimes form hard 
conglomerates, irregularly spread ; but another one, more 
continuous, occurs about the middle and is mainly com- 
posed of carboniferous limestone pebbles. Fossils are 
very rare in this formation in Warwickshire, but two 
remarkable ones were found in it at Kenilworth and 
Coventry, viz., the skull and teeth of Dasyceps Buck- 
landi, and large jaw with -teeth, both belonging to the 
Labyrinthodonts, and may be seen in the Museum at 
Warwick. Fragments of Lepidodendon and Calamites, 
and the casts of a Strophalosia were obtained from a 
now closed quarry at Exhall, between Coventry and 
Bedworth. The Warwick Museum also contains impres- 
sions of several species of large plants which have been 
referred to the genera Caulerpites and Breea from Meriden, 
and silicfied coniferous trees have been met with near 
Allesley, from which the fragments of wood found in 
the drift at Warwick, Rowington, and elsewhere, were 
probably derived. An excellent section of the sandstones 
is exposed in the large quarry at Kenilworth and Meriden, 
where they are extensively used for building. 
The succeeding carboniferous rocks, which include the 
Warwickshire coal field, form on this account the most 
important and valuable formation in the county. The 
area, however, occupied by them is comparatively small, 
being a somewhat narrow tract bounded by the Permian 
on the west and the New Red Sandstone on the east, 
which extends northwards, not far from Coventry, to
