INFERIOR OOLITE : FREESTONES. 
115 
The Lower Freestone, being more thickly developed, and alto- 
gether the more important division, is known as the " Building 
Freestone," although in some localities the upper freestone yields 
good beds of building-stone. It varies in thickness from 
about 45 feet at Uley Bury to 130 feet at Leckhampton. It 
contains Pecten personatus, &c., but no distinctive species. 
The Oolite Marl (Oolite Marlstone of J. Buckman) being 
characterized by Terebratula Jimbria, was termed the " Fimbria- 
stage" by Dr. Lycett. It contains also Terebratula maxillata 
(var. submaxillata), Waldheimia Leckenbyi, Rhynchonclla sub- 
obsoleta, and R. Lycetti : an assemblage not met with in Dorset- 
shire.* 
At the base of the Freestone there is at Leckhampton a bed ot 
" Flaggy Oolite " according to Prof. Buckraan ( = " Shelly Free- 
stone " of Brodie) that is extensively quarried for rough kinds of 
stone-work, and in which there are many forms of life similar to 
those of the Great Oolite.f The strata likewise present great 
similarities in lithological characters with some beds in the Great 
Oolite of Minchinhampton. These lower beds are not separated by 
any marked plane of division from the underlying Pea Grit Series. 
The Upper Freestone (which includes the " Rubbly Oolite " of 
Brodie) is often a pale closely -packed oolite, and is of variable 
thickness, .being from 6 to 20 feet at Stroud and Nailsworth, 
20 feet at Leckhampton, and about 30 feet at Cieeve Cloud. 
In the neighbourhood of Cieeve Cloud and north -east ward?, 
sandy and clayey subdivisions become associated with the higher 
portions of the Freestone Series, replacing to a certain extent the 
Upper Freestone. 
The Coral Bed that occurs in the Oolite Marl has been termed 
the Middle Coral Bed, but other Coral Beds having been subse- 
quently observed, it is noted as the Third Coral Bed (in descend- 
ing order) in the beds of this district. It has heen found at 
Juniper and Birdlip Hills, at Leckhamptou, and Notgrove.
