or more of the strata are wfanting, at other times the order of their disposition seems partially inverted ; 

 their continuity of surface is continually interrupted, so that a section of the earth almost every where 

 exhibits only confusion and disorder to persons who have not made geology more or less their study.

 si(^e of the county of Dorset, a waving line to Scarborough (Jig. 244. * o, a) will part off, towards the

German ocean, the chalk, calcareous sandstone, and other secondary strata or alluvial earths, in which 

 no beds of workable coal or metallic veins occur. On the coast of Lincolnshire, and part of Yorkshire, 

 there is a subterraneous forest (6) about seventeen feet under the i)resent high water mark, and which seems 

 to have extended eastward in the sea to a considerable distance. West of the line between Scarborough 

 and Hull, the county is composed of secondary strata of different kinds, in many parts of which are b^s 

 of ironstone and coal. This district is bounded on the north by mountains of metalliferous limestone, 

 which terminate in Derbyshire, and extend in the west to the mountains of Wales and Devonshire 

 (c, c,c, c). No metallic veins are found east of this line (r, c, c, c) in ^ny part of England. Along the 

 western side of the island the primary and transition mountains are situated, in which metallic ores 

 occur. They constitute the alpine parts of England, extending from Cornwall and Devonshire, through 

 Wales, into the north-west parts of Yorkshire and Lancashire, and tlirough Westmoreland and Cumber- 

 land,

2057. The succession of alluvial, secondary, transition, and primary strata, in England, has been illus* 

 trated by Professor Brande {Outlines of Geology) by two sections, supposed to be taken through them. 

 The first section {fg. 245.) commences with the blue clay of London (1), and proceeding westward through 

 the counties of Berkshire, Hampshire, Wiltshire, Dorsetshire, and Devonshire, terminates at the Land's
