is highly ferruginous with Belemnites. No. 4, as far as could be 
ascertained, the beds being covered up, is about 40 feet in 
thickness. 
The distance from No. 1 section where the Upper Lias 
sands occur, to No. 4, where the same beds are met with, is 833 
yards, and as they are at the former at an elevation of 780 feet, 
and at the latter 695 feet, the fall in the sands is practically one 
yard in every hundred. 
In comparing the various sections, the 18 feet 10 inches in 
No. 1 are represented by the 18 feet at the base of No. 2, and 
the first 5 beds of No. 3, which are 18 feet 6 inches, and the 
three beds above the Upper Lias sands in No. 4, by the two beds 
in the same position in No. 1. 
It will be seen the highest beds here in the Inferior Oolite 
are shewn in No. 2 section, and belong to the freestone; they 
are 10 feet thick, and are covered up with beds probably of the 
same formation. Now, here is a remarkable illustration of the 
further denudation of the Coral bed to which I alluded after 
describing No. 1 section. Although it occurs in No. 3, yet I 
have failed to detect it in No. 2, and it seems to me clear that 
when the denudation set in, the beds of No. 3 were relatively 
at a much higher elevation, and that most likely the ground at 
the back of the hill deflected the current of water, sweeping 
away the Coral bed, as it passed over it, leaving No. 3 beds 
comparatively untouched. 
On reference to the Birdlip section it will be noticed that, 
while there are 60 feet of the freestone developed, only 10 feet 
with the probable further covering up of the bed of a like 
thickness, are met with at Crickley; and further, the whole of 
the Oolite Marl, Rhynchonella Spinosa, Terebratula globosa, and 
Clypeus Plottii beds are absent at the exposed parts of Crickley. 
The height of the sands at Birdlip is 833 feet, while at~ 
Crickley on the promontory nearly opposite, they are 780 feet. 
I fully intended to make some observations on the irregular 
height at which the sands occur in the Cotteswolds, but want 
of time has prevented me.
