If this section is compared with that now exposed on the N. 
side of the rails it will be seen that there is a great difference in 
the thickness of the White Lias beds ; whereas in the latter section 
they are from 10 to 12ft. thick, in the former they are reduced 
to some 34 ft. including the “Landscape stone” or ‘ Cotham 
Marble ” as the base of the White Lias proper in each section. 
This may be accounted for by the S.E. dip of the beds, the 
faulting and the great amount of denudation that is evident 
throughout. That the same disturbance and faulting which 
occurred on the N. side of the rails continued Southwards was 
plainly visible in a trench cut parallel to the rails to a depth of 
about 4ft. Gin. Plate No. 1 taken at the time shows the faulting. 
At the N.W. end were the dark Rheetic Clays with a band of 
Grey Marly limestone in the centre 1ft. 6in. thick. Many black 
specks in this softish limestone appear to be Carbonaceous. Next 
to this comes an infilling of reddish brown Lower Lias, running 
downwards ina V shape to a string, succeeded by Black Rhetic 
Clays, then again by Rubbly White Lias beds upon which rest still 
further on in S. Easterly direction Lower Lais, whilst at the end
