REPORT— 1847 . 
FuUer’B earth rock, as well as the fact that no beds referrifale to the Bradford clay im 
been detected in the district embraced in this notice, fully corroborate theopinioa 
prrviousiy published by Professor J. Phillips, that “in the midland coantia,tlie 
Fuller's earth rock of Mr. Smith does by no means furnish a coostaotor «rtll> 
nuuked line of distinction between the middle (jperat or Hath; oolite and the ioferior 
oolite; and I am decidedly of opinion, that in the northern part of NorthsiDptoo. 
tJiirr. and throughout Rutland and Lincolnshire, there Is but oae thick oolitic nd 
henratii Uk* cornbrash, resting upon brown Bandstonc, which iromediaWy corm 
the upper lias shale.” (Geol. York, vol. i, p. 130.) 
The upper lias which forma the base of the series here described, ocennintbr 
taJli v through which the Welland (lows; small sections are exposed ia thersiliny

It has not been found practicable to trace with precision the faults which lu« 
more or less aflcctwl this series of beds. Near Thrapston, however, a sligjit dblo- 
catioii is viable nn the line of the Peterborough and Northampton railway, afectinj 
the cornbrash, great oolite aud inferior oolite. 
A fmalt disturbance of the inferior oolite near Stamford has been before alluded 
tO{ and some very interesting appearancea of disturbed stmtificatioo, inwhiAtbe 
lower slaty beds and inferior ooliic are Iving at various angles and much confined, 
are aini at the cutting near LufFenham Mill and along the railway line beyoml tlib 
point. Similar ev’idcnccs exist near Stamford, and it appears generally the case (d 
ItRRt numerous instances arc visible) that those portions of the oolitic series which 
abut upon the valleys and form the lower cscarprocnts of the hills have beta nl>' 
js^etl to some disturbance, the beds having been displaced or brou^t down Iran 
higher levels, as they do not appear to occupy their oiigiual horizontal position and 
relative heights. (Outlines, p. 215 .)

flavjng thus attempted a brief review of the stratigraphical arrangement eatl 
romeral rliwacters of these deposits, we shall conclude with a few general obKm* 
tions regarding the nualosries of these beds and the conditions under whicli niey

To the Hm clay, with its characteristic fos-sils and the inferior oolite, bertof

CMmcter of the fauna; for although some of the species mav belong to tkc
