PROCEEDINGS OP THE GEOLOGICAL SOCLETr. [Feb. 5, 



Ascending the escarpment north of Geddington, we again 

 over the same almost inevitable sequence : — 



Great Oolite Limestone. 

 Upper Estuarine Series. 

 LINCOLNSHIRE LIMESTONE. 

 Lower Estuarine, 1, T ,, c , 



Ferruginous Beds, ) Northampton Sand. 



Upper Lias Clay. 



In the discussion after the reading of my First Part, Professor 

 Morris said he " had found a difficulty in reconciling the phenomena 

 of the eastern and western Oolitic areas, but considered that the 

 key of the arrangement was to be sought in the district between 

 Northampton and Stamford." 



I agreed with Professor Morris in the opinion expressed in the 

 latter part of his remarks ; but I would submit that " the hey" has 

 been abundantly found, in the sections already noted, which display 

 such a remarkably uniform and significant sequence of beds ; which 

 sequence occurs over and over again upon unnumbered escarpments 

 throughout the area of the Lincolnshire Limestone. 



Little Oakley and Stanton. 



From Geddington, we pass over the Great Oolite Limestone to 

 Little Oakley ; between which village and Stanion, a valley is 

 traversed which exhibits the usual series of beds, but complicated by 

 the intricate intersection of several small crossing faults. 



Weldon. 



About four miles north-east of Geddington, are the Weldon 

 quarries, whence is obtained the widely known Weldon freestone. 

 The extent of the area which has been broken up into " Hills and 

 Holes " (much of it planted over with trees of considerable growth) 

 bears testimony to the antiquity of the excavations, and to the 

 quantity of stone which has been raised. This freestone is a rather 

 coarse-grained Oolite of a ruddy hue, having frequently a glittering 

 fracture. When a disengaged block is struck with a hammer, " it 

 rings like a bell " (to use a quarryman's expression) : a peculiarity 

 which more or less characterizes the good freestones of this forma- 

 tion. It was much used in ancient times in the erection of churches 

 and other prominent buildings throughout a very considerable 

 district. 



Mr. Judd obtained a fine series of fossils from the Weldon 

 quarries, a list of which will be published in his Memoir. I only 

 succeeded in noting the following: — 



Pecten articulatus, Schloth. 

 Rliynchonella varians, Schloth. 

 Monodonta ? 



Nerinsea cingenda, Bronn. 

 triplicata, Bronn. 



Phasianella elegans, Mor. § Lye. 



parvula, Mor. Sf Lye. 



Pontonis, Lycett. 



Acrosalenia (spine).
