He remarked, “The ‘ Bone-bed’ at this place is far less 
rich in organic remains than at Coomb Hill. Its prevailing 
character is that of a fissile micaceous sandstone, some- 
times acquiring a flinty hardness, and presenting at rare 
intervals accumulations of osseous and coprolitic frag- 
ments, similar to those at Coomb Hill.”’ 
In 1842, the Rev. P. B. Brodie, in a “Notice on the 
Discovery of the Remains of Insects in the Lias of Glou- 
cestershire. with some remarks on the Lower Members of 
this Formation,’* gave a more detailed stratigraphical 
account of the section above my bed 7, separating 
Strickland’s 22 feet of black laminated clay into nine 
sub-divisions. 
Strickland in a paper “On Certain Impressions on the 
Surface of the Lias Bone-bed in Gloucestershire,”? recog- 
nised all Brodie’s sub-divisons, and made an additional one. 
This corrected section is quoted in Murchison’s “ Outline 
of the Geology of Cheltenham,” in 1844.4 In the follow- 
ing year Brodie’s classic work on “ Fossil Insects,” was 
published, wherein Strickland’s new sub-division is
