From this profile we notice that we have the following pecu- 
liar and perhaps more or less local deposits to deal with :— 
1st, B. Dark brown sandy beds. 
2nd, E. Bored bed and White Freestone. 
3rd, G. Ragstones and Limestones, with fossiliferous partings. 
4th, H. Yellow Micaceous Sands. 
and one of my objects in this paper is to prove that I have 
correctly determined the position of these deposits, and to point 
out the striking difference that exists between the strata here 
and those of the Stroud area, notably in the position of what is 
generally called the “ Bored Bed.” Of the four series of rocks 
which I have mentioned above, E and H are probably the most 
‘peculiar, and therefore the most important. It was on account 
of a question which arose as to the position of the “Bored Bed 
and Freestone,” or E, that my attention was first called to these 
cuttings, and I was induced to make a thorough examination 
of them, and it is this Freestone which I wish to call, for better 
distinction, the Notgrove Freestone (it being best developed 
near Notgrove Station.) The top of it is sometimes separated 
into a distinct bed, but whether separated or not it is always 
very much bored by Annelids, whilst the upper surface, but no 
other part, is almost entirely covered by a thin flat oyster, 
probably indicating the occurrence of a considerable cessation 
of actual deposition after this Freestone had been formed, and 
before the next strata succeeded. Considering too the distance 
over which we have noticed this Bored bed and its oysters, the 
Same conditions must have prevailed over a wide area, viz., 
from near Bourton-on-the-Water almost to Syreford; and I 
have little doubt that this area must have been a large 
Oyster bank, existing much under the same conditions that 
_ obtain in the present day—probably in shallow water, not too 
far from the shore. Besides this, I think, from the appearance 
of the rock, its upper surface being pitted and scooped out, 
we must suppose that this deposit remained in this condition 
for a considerable period, and underwent a process of hardening, 
during which time strata were being deposited in other locali- 
ties. This again leads us to ask what other strata were being
