SHARP OOLITES OP NORTHAMPTONSHIRE. 



265 



beds of the Lincolnshire Limestone : — Beneath 5 feet of rubbly 

 oolite, are a series of shelly, coralline, and oolitic bands (having an 

 aggregate thickness of 15 feet), which have yielded a perfect harvest 

 of fossils, including many forms not previously known ; some of 

 which were described and figured by Dr. Lycett in an Appendix to 

 Professor Morris's Paper. Under these shelly bands, is a soft marly 

 limestone, 3 feet ; and below this, 15 feet of " coarse shelly oolites 

 and freestones." 



Nearer Grantham, is the Little-Ponton cutting ; in which is ex- 

 posed 50 feet of the beds of the Lincolnshire Limestone. A well in 

 the neighbourhood pierced through some 60 feet of the same beds.
