will be seen by the sections this is a much more persistent 
feature, and it is present from near Bourton-on-the-Water 
to the cutting on the railway, about 14 miles east of Andovers- 
ford, a distance of 7 miles. Its position, if I have satisfactorily 
proved the position of the Notgrove Freestone below, is of 
course much above the Bored bed on the top of the so-called 
Upper Freestone of the Stroud area, of which I have endea- 
voured to shew there occurs a feeble representative in section 
II. bed 17, whilst No. 2 of the same section contains this 
Bored bed. We have, therefore, the two horizons shewn in a 
cutting one above the other, although we must examine the 
other sections to see what a much greater amount of deposits 
really occur between them. Above this Bored bed comes a 
very thin layer of mud, or debris, and during one of my later 
visits to cutting ITI., at a point to the east of where section 
IV. was taken, I observed a bed, 1 foot 3 inches in thickness, 
on the top of the Bored bed, containing flat oysters, Trigonie, 
etc. This bed is irregularly deposited in kind of pockets, 
and it did not extend any great distance from the point where 
I observed it, but thinned out to a thickness of an inch or so 
rather suddenly. It is evidently usually represented by the 
layer of mud which occurs on the top of the Bored bed in other 
places. 
Above this we find the Upper Trigonia Grit, a division of 
the Inferior Oolite, which is so well known that it does not need 
any lengthened notice from me. In this district it usually con- 
sists of three very hard beds, of a somewhat dark colour, and 
separated by partings of marl. The beds contain numerous 
impressions of Trigonie; Rhynchonella hampenenis, 8. Buck. 
occurs in clusters, Rhynch. spinosa, Schloth. Waldheimia Hughesi, 
Dav., Wald. carinata, Lam. and other brachiopods occur, as well 
as Am. Parkinsoni. The top bed is generally the hardest of 
any, and contains numerous fragments of shells. This Grit is 
probably one of the most persistent and recognisable horizons 
over the entire Cotteswolds, and I have no doubt that it is the 
exact equivalent of this bed which I have met with at Gall- 
hampton, Blackford, and other places near Sparkford, in
