could find an adequate cause for the effects that have been 

 produced in it, along an extent of sixty miles in length and 

 twenty miles in breadth." (GeoL Trans,.^ vol. ii. p. 124.) 



Dr. Buckland's paper on the formation of valleys by the 

 elevation of the strata that enclose them, is so closely con- 

 nected with the subject of Mr. Martin's memoir, that we shall 

 not find a more appropriate opportunity of adverting to it than 



sand' ^c, of the jp^^ 



here. The first object of this eminent geologist is, to show the 

 arrangement of the strata immediately to the south of New- 

 bury, and, in particular, to describe that remarkable denu- 

 dation within the chalk, which contributed to form the Valley 

 of Kingsclere. {Jig. 131.)

On inspection of the section which accompanies the paper, 

 a striking similarity to that of the Weald valley, in con- 

 nection with the London basin, will be at once recognised, 

 and it will further elucidate the relation between the formation 

 of basins and valleys of elevation. They are both here intro- 

 duced. {Jg. 132, 133.)
