In addition to the fossils tabulated above, many other minute 

 specimens have been obtained from the Barnack Rag ; which, from 

 their being new or young forms (although frequently well preserved), 

 it has been found impossible to identify with described species. 



Ueford. 



In ascending the hill into Uiford, the almost tiring reiterated series 

 of all the beds from the Lias upwards to the Great Oolite Limestone 

 inclusive is again crossed. At less than a mile east of Ufford, and 

 at a very slightly lessened elevation, are quarries in the Lincoln- 

 shire Limestone. Under about 16 feet of very oolitic stone, are 

 2 feet 6 inches of slates and " poltids," which repose upon the 

 Lower Estuarine Sands, — seen to the thickness of 9 feet, disposed 

 in thin seams, exhibiting much variation in colour, and containing 

 horizontal and vertical plant-markings.
