have but little evidence to fix the southern extent of the Cepha- 
lopoda Bed between Bath and Little Sodbury. At Bath we 
have in the Midford Sand fossils that characterize the Cephalopoda 
Bed; and at We'ston, the Kev. H. H. Winwood has found an 
iron-shot limestone that closely resembles that bed in lithological 
character. (See p. 99.) Near Bath there is not only considerable 
local attenuation of the Midford Sand, but evidence of local
