2. Several ferruginous beds, with reddish-brown sand in numerous 
pockets and hollows, giving to the rock a nodular appearance. 
The beds are Oolitic, and are thickly speckled with large 
ferruginous grains, and frequently pisolitic. There are layers 
of ferruginous sand in the partings of the beds—Terebratula 
plicata, Nerinzeac Oppelensis, Aviculata complicata, Lima 
punctata, &c. : : : : : < ; : Stace (0, 
3. Light brown Oolitic compact Limestone, with layers of detritus 
of spines of Echinide and fragments of Crinoidea alternating. 
The detritus is darker in colour than the other parts. . 3), 7 
Two beds of white Oolitic Limestone, in some parts resembling 
the building freestone above the pea grit. The granules are 
small and the beds compact. 
6. Several beds of whitish-brown Oolitic Limestone, composed to a 
large extent of shelly detritus, broken spines of Echinide and 
fragments of Crinoidea, similar to No. 3. : : : «AMO

Four beds of compact Oolitic Limestone ; in parts rough, in other 
parts fine-grained ; the fragments of Crinoidea are numerous. 12 0 
The Ferruginous Sandy Limestones are not exposed; there 
is probably a thickness of not less than nine feet of the lower 
beds beneath the above. The division between the Pisolitic 
beds and the Limestones is well shown in this Section. 
The Section is taken from the left side of the fault in the 
north-east side of the quarry.
