British Association. From an account I have received of some 

 Lias sections in Nottinghamshire, it may be inferred that the 

 same series also occurs there in its proper position. Mr st of 

 the pits at Barrow do not exceed 30 feet in depth ; but some 

 have been opened to a depth of 42 feet, the lowest stratum 

 being a bed of blue marly clay. 



The limestones are used in Leicestershire for the same eco- 

 nomical purposes as the Warwickshire paving-stones, and are 

 equally well adapted for this object ; but they were not employed 

 on the spot, when I visited Barrow some years ago, for making 

 hydraulic lime, as they are in the extensive quarries belong- 

 ing to my friends Messrs. Greaves & Kershaw at Wilmcote, near 

 Stratford-on-Avon, though I have little doubt they might be 

 profitably employed for this purpose. 



In places there are several small faults ; and in one pit the 

 lower strata are thrown up so as to form a complete saddle, of 

 limited extent, at right angles to Mount Sorrel, not far off, 

 showing, on a small scale, what the effect of such a dislocation 

 would be on a large one. At Wilmcote, in Warwickshire, there 

 are also indications of numerous faults in all directions round 

 the district — more than has generally been supposed. Thus the 

 "firestone,^' which is the lowest and hardest stratum worked, 

 crops out at various points and dips at a considerable angle, on 

 the higher ground, and the. several bands of Insect-limestone 

 and shale lie in a basin fornied by the outcrop of the lower bed. 

 The " Lima-he^^f" containing the usual characteristic fossils, 

 occur in places in their normal position, more or less denuded. 

 The Insect-beds are more numerous, at least eight courses 

 divided by thick shale, in Warwickshire than in Leicestershire, 

 Worcestershire, Gloucestershire, or Somersetshire; and the other 

 Liassic and Rhsetic beds being present below them gives a 

 completeness to the Warwickshire sections not met with else- 

 where. Except in No. 3 of the above section, shells are scarce ; 

 below this I observed only a few of Ammonites planorbis and 

 Aptychus, and a species of Inoceramus common in the shale at 

 Brockeridge Common, near Tewkesbury, in Gloucestershire, and 

 there associated with numerous and beautiful specimens of the 

 same Ammonite. The fine Saurians and fish for which this 

 district (Barrow) has long been famous occur more or less in 

 all the shales and limestones, though some courses are richer 

 than others, more so apparently with respect to the latter than 

 the same zone in Warwickshire. But neither at Barrow nor in 

 other places are the Saurians or fish confined to this division of the 

 Lias, but, as at Lyme (as Mr. Day has shown in an able and 

 interesting paper read at the meeting of the British Association 

 in Birmingham in 1865), have a wide vertical range. The genua
