At the southern end these lower clays are about 15 feet thick be- 

 tween the root-bed and the ferruginous band, upon which latter they 

 repose, and below which the oolite extends a few yards only into this 

 part of the cutting. It may be remarked, that the beds exhibit a 

 synclinal dip towards the centre, at the angle of which a small fault 

 is visible, giving to the position of the stem-bed in this section an 

 irregularity, and som.ewhat affecting the parallelism of it in regard 

 to the other sections. 



The Aunby Cutting, the contour of which is very irregular, 

 although not exposing so complete a series as the last, still presents 

 some differences, more especially observable in the arrangement of 

 the plant-bed, which m this section exhibits a different mode of ac- 

 cumulation, being here replaced by two distinct bituminous layers, 

 each of which has its accompanying root-bed ; the upper bituminous 

 clay attaining the thickness of 2 feet, with lignite and impure coal ; 

 the lower is about 3 inches, and, with its accompanying root-bed, 

 thins out towards the north end of the cutting. The following is the 

 series about the middle of the cutting :—

The oolite extends along the base of the cutting. 



With the Essendine Cutting, now to be described, the argillaceous 

 and shelly series terminate, as far at least as the Railway sections are 

 concerned. In descending order, and with a view of rendering the 

 peculiar characters and affinities of these beds more intelligible, the 

 physical features and oi'ganic contents will be more fully detailed. 

 Obsernng the same order of arrangement, we commence with the 

 upper beds (1), which are full of Oysters, with occasional patches of 

 Serpnhe, 3 to 5 ft. ; the rock (2) immediately l)clow the oyster-l)ed 

 is sandy and marly, becoming occasionally very compact, calcareous,
