344 R. I. MuRCHisoNj Esq. and H. E. Strickland, Esq., on the 



is at Coton End, on the south-east side of Warwick, where the following sec- 

 tion is exposed : — 



a. Soft, white sandstone and thin beds of marl 8 feet. 



b. Whitish sandstone, thick-bedded 12 



c. Very soft sandstone, coloured brown by manganese, called " Dirt-bed" by the 



workmen 1 



d. Hard sandstone, called " Rag," about 2 



23 

 The dip about 3° to the S. 



The bones are principally found in the so-called " Dirt-bed." They are in 

 the same rolled and fragmentary condition as at Leamington, but in a state of 

 much greater decomposition. When first taken from the quarry, they re- 

 semble stiff jelly, with singular hues of blue and red. It is necessary to re- 

 move them with great care from the quarry, and when dry, to saturate them 

 with a solution of gum arabic, as the best means of preserving them. The 

 only specimens which exhibit any distinct zoological characters, are some 

 teeth obtained by Dr. Lloyd, to whose kindness we are indebted for the 

 figures given of them in Plate XXVIIL, figs. 6, 7, 8. 



The light-coloured sandstone extends from Warwick, by Guy's Cliff, to 

 Wooton Grange ; beyond which it is succeeded by the underlying redder 

 sandstone of Kenilworth. In a quarry in the grounds at Guy's Cliff, is the 

 following section : — 



Sandstone and beds of marl 8 feet. 



Solid sandstone, whitish or grey, occasionally of a reddish tint 12 



Red, micaceous marl, with wedges of sandstone 8 



Solid, light-coloured, reddish tinted sandstone, about 20 



48 

 The bedding very irregular. Ripple marks occur on some of the beds. 



We have now to speak of the redder sandstone which underlies the light-co- 

 loured strata. The upper part of this red rock consists of flaggy beds, with 

 marly wayboards. In a quarry, south-east of Ashow, on the left bank of the 

 Avon, is the following section : — 



a. Thin, flaggy beds of red sandstone 6 feet. 



b. Thick-bedded red sandstone 8 



Calcareous matter pervades the thin beds «, in concretionary patches; and 

 where that is the case, the sandstone is intensely hard.
