in Yorkshire, Derbyshire, ^c. 9^ 



nor caa I bear any thing more of the appearance of this 

 Oalite, near to Markct-Raisia E, Caiston W, Brigg E, 

 crossing the Hamber N W of Barton, near Mai-ket- 

 Weighloii W, and near Pocklington, where I suppose to 

 be its range, and on which points I solicit the assistance of 

 your readers and correspondents. 



The first or outer-raised tract shown in the map and 

 mentioned p. 30, of your last Number, 1 now suppose to 

 have a north-eastern corner extended to near Leavening, 

 between Acklam and Buryfhoqie, near to the ed2:e of the 

 Chalk ! ; the eastern boundary fault, after passing W of 

 Bawtry and Thorne, as there mentioned, i)iobabiy proceed- 

 ing near Snaith, W of Ilowden, E of Aughton, W of 

 Pocklington, W of Garraby-street Inn on The York and 

 Bridlington Road (being here very near to the Chalk), near 

 xlcklam ; and after turning nearly at right angles near 

 Leavening, the same probably -proceeds near Crambe S, 

 SheriB'-Hutton S, Stillington S, Kasingwold, Thirsk S\V, 

 to near the Swale River about Ainderby- Steeple, where I 

 suppose it to turn again at rather more than a rii>;ht angle, 

 pass NW of Northallerton^ NW of StokcsW, near 

 Ormsby, Wilton, and fCirklcatham, and enter the German 

 Ocean near or on the SE of Redcar, near the mouth of the 

 Tecs : instead of ihis fault turning westward up the course 

 of the Wliarf River, as I conjectured a year ago (p. 80), 

 before having seen the Country, as will be further noticed 

 pre-.ently. 



By this prodigious eastern/a .v//, it has I expect happened, 

 that the magnesian or Yellotu Lime Hock (with perhaps 

 Coal-measures above it in some places, Report i. 132) oc- 

 cupies the surface under the Gravel, Pf^ut, 8ic. on its west 

 side (p. 31) from near Nolliiigham to somewhere near 

 Pocklington* ; but on its easiern^or outer side, arc Red Marl 



strata,
