.98 Mr. Farcy's Geological Ohservations 



vale of the Hull Klver near Great Driffield, N\V, near ta 

 West-Lutton, Wiiitringham, Kirby-Misperion, Helnisley, 

 Oid-Byland, and Over-Stilton, to the great fault perhaps, 

 somewhere N of Northallerton; and which occasions tlie 

 IjOJidon Clay series to advance beyond Kendall, the Chalk 

 beyond Wintringham on each side, the Chalk-marl ahnost 

 to Helmsley, the Aylesbury Limestone to Keebeck, and the 

 under strata of Coal-measures and Alum-shale near to 

 Osmotherley at least ; the dip being obliquely towards this 

 line, itself declining eastward, but unequally in different 

 parts ; a low part of this trough, seeming to occasion the 

 running of the Derwent W from near Filey to meet other 

 streams coming eastward, on the N of Malton. 



The upper edge of this Limestone stratum has been men- 

 tioned, in speakmg of the Chalk Marl ; its lower edge and 

 line of its extent on the surface may be traced, near Wes- 

 tow Crambe, Bulmer, Terrington, Dalby, Bransby N, 

 Owston, Cnxwold E, (with -detached hummocks at the 

 Towns of Crake and Coxwold); then turning NE and E, 

 owing to the deep and large excavation of the Rye River 

 and some of its south branches (which has exposed the 

 Coal-measures on Grinistoue-nioor E of Yearesley) N of 

 Newboro' Park, NE of Yearesley, SE of Shackleton, 

 bv Hovingham, crossing the Rye NE of this, by Stone- 

 grave, S of Oswaldkirk (having inclosed a Limestone cap 

 yr hummock ai Colton, and NW of it), Arapleforth, 

 Oldstead, Kilburn S, Sutton under WhitsunclifFE, Thirlby, 

 Bohby, Kirby-Knowle NE, (the town standing on a de- 

 tached hummock), Cowsby, (Keebeck standing on a de- 

 tached hummock), Arden-liall N, Hawnby SW, S, andSE, 

 Carleton \\ mile N, Skiplam N, Gillamoor N, Button in 

 the hole S, Lestingham S, Cropton SW, S, and SE, New- 

 ton N, Sahersgate or Half-way house S and SE, Lilla-cross 

 S, Braxey VV,"Everly SW and S, (with ti detached hum- 

 mock E), Falsgrave S, Oliver's Mount ?, Whcatcroft W, 

 Osgodby, and Gristhorpe N, where it shows its under strata 

 on'the shore of the Gc^rnian Ocean : such are the results 

 of my observations and inquiries, respecting the Locality 

 of this interesting Oalile Rock, on which I shall be thank- 

 ful to receive any corrections or additional particulars, from 

 the kindness of your Readers, particularly such as can enu- 

 uieratc the extraneous fossils found in particular spots. 



From near Gnslhorpe and Filey above mentioned, the

 veral local peculiarities of dip, that I mu:5t reserve for an-
