GR EAT OOLITE SERIES : STONY STRATFORD. 391 
Here we have a passage from the Upper Estuarine Series into 
the Great Oolite Limestone, with intermediate beds that may be 
said to represent the Stonesfield Series.* 
Prof. Green (MS.) mention?, that "An old brick-pit in 
Thornton, just opposite the turn to Beachampton, showed rubbly 
Cornbrash, resting on pale-blue sandy clay ; the clay was said to 
be 15 or 20 feet thick." It would belong to the Great Oolite 
Clay. 
A boring for the Waterworks at Stony Stratford (town) 
furnished the following section, of which the details were com- 
municated by Messrs. Le Grand and Sutcliff (see p. 511) :

At Old Stratford borings have been made to depths of 109 and 115 feet, 
mainly through blue clay, sand, and silt (Drift, etc.) reaching " rock " at 
depths of 109 and 113 feet respectively. 
A well-section at Brick-kiln Farm, S.E. of Stony Stratford, 
proved the following strata, the details of which were communi- 
cated by Mr. W. H. Daltcn :

I have inserted the Upper Estuarine Series, as it is no doubt 
represented, judging by the evidence obtained at Deanshanger.
