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

was uniformly a blue clay, in parts rather inclining to a lhaly 
ftrudture, and contained many calls of tellinae, a very little 
pyrites, and fome few fmall, but very elegant, belemnites. 
Thefe are all the ufual foffils 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 lizes from that of a pea to a child’s head. 
They lay in no fort of order that I could find. Flow deep 
this appearance might have continued I cannot determine, but
