solid bed of White Lias some 6in. thick succeeded by Rubbly 
White Lias tothe top nearly. At the base are the Black Rhetic 
clays. 
One other section may be given showing a larger development 
of the gravel beds, and is of interest as indicative of the great 
amount of denudation that has taken place and as marking the 
spot where Mammalian remains have been found.

In one of the bands of yellow clay portions of Elephant’s 
tusk and the plates of Rhinoceros teeth were found. The gravel 
beds here about 37ft. above the present river level are therefore 
proved to be the usual Mammalian gravels, and correspond with 
those on the left bank of the river at Twerton, and are similar in 
composition and contents. They are made up of Mountain 
Limestone, Old Red, Oolitic Coral (Isastrea), Greensand, Lias, 
reddish Grit with white quartz pebbles, Old Red Conglomerate 
and Dolomitic Conglomerate, Flint, Chert, and a reddish 
Quartzite. Some of the latter were of considerable size. One 
block seen in Plate No. 2 near which the six foot rod 
rests, measured 4in. by 3in. by 3in. nearly square with the angles 
rounded off, another of reddish grit 10in. long. 
One large block of Mountain Limestone well smoothed, with
