[Feb. 5, 



like that described by me as occurring in the sand-bed at Kings- 

 thorpe), consisting of vertical root-perforations surmounted by hori- 

 zontal bituminous layers. This Upper Estuarine series was not 

 wholly exposed at Essendine : ' at Danes' Hill, it had a thickness of 

 about 22 feet ; while at Aunby, it had thickened to no less than 

 32 feet. The usual ferruginous band, of the thickness of about a 

 foot, based these clays. 



At the southern end of the Danes'-Hill cutting, and immediately 

 underlying the ferruginous band, an upper bed of the Lincolnshire 

 Limestone was exposed. 



In the Essendine cutting, and probably in the Great Oolite Clay 

 (the same clay as that at Banthorpe and at Eirklington), immense 

 bones of Cetiosaurus brevis and of C. longus were found ; which 

 bones are now in tbe Museum in Jermyn Street. 



As no useful end can be served in keeping distinct the fossils of 

 these sections, I have grouped them together in the following list, in 

 order to economize space and to avoid repetition.
