It is unfortunate that so little reliable information is available ; 

 but it was interesting to find Bed 5 6, which was replete with 

 specimens of Cardium cloacinum and Placunopsis alpina. 



Milton Lane, Wells. — About a mile to the north of Wells is 

 the section that was described by the Rev. P. B. Brodie in 1866 as 

 that of ' Milton Lane.' * In it Keuper, Rhaetic, and Lower Liassic 

 rocks are exposed, and it is of especial interest in that it shows 

 the last-named in close proximity to the older rocks of the Mendip 

 Hills still maintaining their normal lithic characters. 



Two faults, unfortunately, affect the rocks : the one throws the 

 Tea-green Marls against the Red ; while the other disturbs the strata 

 which occupy the stratigraphical position of the Cotham Beds, and 

 renders exact details difficult to obtain.
