Still going east, at Midford, three miles south of Bath, 
in the first railway cutting south of the station, the junction 
of the Fullers’ Earth and the Inferior Oolite is well shown. 
As at North Stoke and at Stantonbury only the Parkinsoni 
zone of the Inferior Oolite is represented, these beds resting 
directly on the sands. From the Fullers’ Earth, which 
consists of Lower Fullers’ Earth Clays, a rich series of 
fossils may be obtained. The following species are com- 
mon.
