out from under the chalk, and we pursued it along a continuous 

 line of quarries on the right of the road to Brough, hy EUerker, 

 almost to the Humber, in which at low water this rock is said to 

 appear. The stone is chiefly used for repairing roads, but in 

 some places is burnt to lime ; its general character is remarkably 

 ochreous ; two beds are distinguishable in it— the upper sandy, 

 and decomposing into round balls ; the lower decidedly ooUtic, 

 and variegated internally with patches of deep blue. In the 

 fossils of this whole range, we found nothing indicative of the 

 upper oolites, but obtained several shells characteristic of the 

 inferior;* and we do not hesitate to consider it as the continua- 

 tion of that rock passing the Humber from Lincolnshire. 



A httle further to the east on the left hand side of the same 

 road, we met with the third range which we had designed to 

 examine exposed in a line parallel to the former in sand pits, at 

 North Newbald, South Newbald, and South Cave ; it appears 

 also on the road about half-way between the last-mentioned 

 places. Further south we wera not able to trace it, but think it 

 probable that the hill at Elloughton belongs to the same stratum, 

 which would bring its course down to the Humber : at North 

 Newbald it passes under the chalk without any interval between 

 the two rocks. The character of this stratum is well shown 

 in the section exhibited at the latter place, of which a drawing 

 has been made by Mr. Phillips ; it consists of loose sand abound- 

 ing in casts of shells, and containing masses of a hard calcareous 

 stone marked by numerous remains of gryphoea dilatata. Mr. 

 Phillips at once recognised in it the Kelloways stone, such as it 

 occurs at the base of Scarbro' Castle Cliff, and found in it the 

 pecuhar ammonite of that rock. (A. Calloviensis of Sowerby.) 



The remaining object of our investigation in pursuing the line 

 from west to east across the strata to the chalk, was the clay 

 which appears in Elloughton Dale under the red chalk. This 

 stratum we traced southward as far as VVelton, and northward 

 to Brantingham, and there can be no doubt that it is the same 

 bed which throws out the springs at Newbald, near which place 

 its outer edge must pass under the chalk, for there the chalk 

 rests immediately on the subjacent Kelloways rock. The best 

 exhibition of it is in Elloughton dale, where there is a section 

 of the chalk marie, red chalk marie, and blue clay: the red chalk 

 marie abounds here with the same small belemnites as it con- 

 tains elsewhere, but in the blue clay there are none of these. I 

 found in it one of the large belemnites which occur in the clay 

 at Specton, and Mr. Phillips found two valves of the Ostrea 

 deltoidea (of Sowerby), with carbonised wood attached to them.
