Dr. Hout (Quarterly Journal of the Geolog. Soc., 1863, p. 306), 
has described the Upper Ragstone beds as running through the 
Lower Cotteswolds to Dundry, and along the whole belt of 
Oolite through Dorsetshire and Somersetshire. At Horton 
Rectory, near Hawkesbury, the Ragstone beds are as follows :—

A. Upper Ragstone, white thin-bedded friable Oolite ... + ee Le ae 
B. Lower Ragstone, massive hard brown Limestone in two or 
three beds, with many fossils, about 333 See re US 
The hard brown Limestone appears to represent one or more 
beds of the Clypeus Grit of the Stroud district. 
At Midford viaduct, near Bath, the White Oolite is described 
by the Rev. H. H. Winwoop as immediately underlying the 
Fuller’s Harth. It consists of four beds, altogether about 
14 feet in thickness, becomes a brownish white in the lower 
portion, and contains casts of Trigonia, &c.

From these descriptions it will be observed that there is a 
gradual and regular development of the White Oolite as it 
extends through the Cotteswolds towards Dundry, where it 
attains its maximum thickness. The hard brown beds are 
absent in the north eastern area, and the soft marly Oolite in 
the middle and south western areas. A few more characteristie
