tellarie, &c. are very abundant; the blue clay has here been 
opened to the depth of ten feet. Very recently have been dis- 
covered at this spot, in the loam, fragments of a tooth and 
bones of an elephant, and a broken tooth of a rhinoceros. 
In the middle of the village of East Winch, by the side of 
the road leading to Lynn, Ostree and Rostellarie were dis- 
covered on sinking a well; and on Mr. Forster’s farm, in the 
same parish, similar shells were found. 
At Tottenhill brick-yard, a short distance from the road 
leading from Lynn to Downham, and at Watlington, the 
same bed of blue clay is met with, inclosing similar shells to 
those at West Bilney. 
The same kind of blue clay was opened last summer about. 
half a mile to the south of Middleton ‘Tower, in a valley run- 
ning parallel to that of the Nar, and separated from it by the 
high ground on which the village of Middleton stands; a small 
stream takes its course through this valley, emptying itself, as 
the Nar does, into the Ouse at Lynn. Ostrea edulis and 
Turbo littoreus were found six feet below the surface. 
In some localities, with the Ostree have been found Cardia, 
Mactra, and other shells, of which the following is a list. The 
greater number of the oysters are large, thick, and antiquated ; 
they and the Rostellarie are very abundant; Natica glaucina 
is next in abundance; Pecten and Cerithium are scarce. The 
shells have not suffered by attrition, but few are broken, and 
none of them are mineralized.
