SECTION OF THE LIAS CLAY IN A RAILWAY-CUTTING 
NEAE STOW-ON-THE WOLD. 
By the Eey. S. Lucas, E.G-.S. 
As Mr. E. Hull of the Geological Survey, in his ' Geology of the 
Country around Cheltenham' (1857), p. 24, complains of the scarcity 
of sections of the Upper Lias in that district, and as a section in the 
Eailway, near Oddiugton and Stow-on-the-Wold, exhibits a section 
of Liassic clays, which appear to me to belong to the upper series, I 
beg to offer you the following rough but accurate account of the bed 
there exposed. 
The list of fossils has been made with the assistance of a geolo- 
gical friend in London. 
I believe the section here described is not at the very top of the 
Lias, for on the hill-side on either side of the valley the Lias ascends 
considerably higher than at the railway-cutting. The cutting, which 
is in the parish of Mangersbury, is about twenty-five to thirty feet 
deep, and the section is as follows : — 
There are no fossils in this bed. It has 
been probably mostly washed down from 
higher ground. 
This is almost one compact mass of shells :
