DEAR SIR, 
$ r T'^HE appearance of the foil which fell under my own in- 
A fpection, on opening, a well at Hanby, the feat of Sir 
c. buck, in Lenton parifli, Lincolnfhire, being, as far as I 
can recoiled!, quite Angular, I hope you will not think this 
account of it unworthy the attention of the Society. 
The fpot on which the well was funk is nearly on a level 
with Lincoln Heath, and of courfe high ground compared; 
with the fen, which is diflant from it above fix miles. The foil 
was uniformly a blue clay, in parts rather inclining to a lhaly 
flrudlure, and contained many calls of tellinae, a very little 
pyrites, and fome few final! , but very elegant, belemnites. 
Thefe are all the ufual foflils of clay ; but what I think with- 
out example is, that through the whole mafs of clay were in- 
terfperfed nodules of pure chalk, evidently rounded by long 
attrition, and of all fixes from that of a pea to a child’s head. 
They lay in no fort of order that I could find. How deep 
this appearance might have continued I cannot determine, but 
®° water having been found at the depth of thirty feet, the 
6 trial
