deposited during such a period? Whether we have any reason’ 
to suppose that in other parts of the Cotteswolds or in other 
parts of England we can find any beds which we could imagine 
to have been deposited between the time of the deposition of 
this Freestone and the deposition of the Upper Trigonia Grit, 
and probably contemporaneous with the deposition of the thin 
stratum of mud which immediately covers it. Before we can 
settle this point we must see whether we can determine the 
actual position of the Freestone, whether it possesses any 
equivalents in other parts of the Cotteswolds, and what those 
equivalents are ? 
When Mr Witchell and myself inspected the Notgrove 
cutting, and I called his attention to the Gryphea bed, he said 
that undoubtedly the members of the Cotteswold Field Club, 
when they visited this part of the line, had considered this 
Freestone to be the well known Upper Freestone, which also 
possesses a Bored bed. They then supposed the absence of the 
Gryphea Grit, and that the Upper Trigonia Grit there shown 
was deposited directly upon the Upper Freestone (excluding 
in that case beds E, F, G, H,)* and producing only another 
illustration of the alleged thinner condition of the Inferior 
Oolite towards the east. But when I was able to show the 
existence in this cutting of a Gryphea underneath this Free- 
stone, then it was of course necessary for me to prove that 
what I had found was the Gryphea sublobata of the Gryphite 
Grit,+ and not another species, since by ‘alleging that I had 
found the Gryphza Grit below the Freestone, I at once altered 
the position of the Freestone. Nowhere else in the Cottes- 
wolds had the existence of a Freestone 12 feet thick above the 
Gryphite Grit, and below the Trigonia Grit, been recognised ; 
and if this were really the Gryphite Grit below, it naturally at 
* In the Stroud area the Gryphza Grit comes in between the Upper 
Trigonia Grit and the Upper Freestone. Southwards below Stroud the 
Upper Trigonia Grit rests directly on Freestone, so that this supposition was 
a most natural one ; while the state of things that actually exists has proba- 
bly no parallel in the Cotteswolds. 
+ Specimens produced at the meeting of the Cotteswold Club, March, 
1887, were at once identified.
