292 LOWER OOLITIC ROCKS OF ENGLAND : 
the western side of the Cotteswold Hiils : indeed in places we 
find that the formation comprises in bulk about one-third of marl 
and clay to two-thirds of limestone. 
At the western end of the railway-cutting north of Hampen, 
the Fullonian beds (Fuller's Earth) are exposed, while the over- 
lying strata of Great Oolite are much obscured. East of the 
bridge also we find beds of Great Oolite limestone much tumbled 
and obscured, but further on there is a clear sequence of beds from 
the Fuller's Earth, through the Stonesfield Slate Series and 
Great Oolite. The general section which I measured in detail is 
as follows :--

Immediately above the slaty beds in a cutting near Notgrove, 
Mr. E. A. Walford noted a Crinoid-bed with Millericrinus Pratti 
This bed is a brown shelly marl, with Ostrea, Cyprides, and 
Foraminifera, and with rolled and bored stones. In the overlying 
freestones he obtained Ceritella, Cerithium, Cylindrites, Nerin&a, 
Corbula, Tancredia, &c.* 
Mr. R. F. Tomes has noted the occurrence of a thin Coral-bed, 
with Isastrcea, ThamnastrcBa, and Microsolena, at Aylworth, on 
the railway between Bourton-on -the- Water and Cheltenham.! 
This layer occurs immediately above the Stcnesfield Slate. 
The details shown in the section of the Great Oolite north of 
Hampen (C.) were as follows : the numbers attached to the sub- 
divisions are those given in the section Fig. 43, p. 131 :
