story of a man whose well was s supplied from this stratum, who not 
being satisfied with the quantity of water yielded, and desiring to 
increase the supply, penetrated to the underlying sands, and lost the 
pure element altogether. The following is the succession of beds as 
furnished by the quarryman :—

in all about 33 or 34 feet, exclusive of the clay band. I could find 
no example of Trigonia, or R. spinosa, in the overlying beds; though 
‘Mr. Moore informed me that he had taken R. spinosa in a young 
form in the Upper Rags, and had even met with it as high up as the 
Bradford Clay. 
The considerations which present themselves on a review of the 
foregoing facts, are of a nature to prevent hasty conclusions; but I 
think I have shown sufficient reason to justify and call for a more 
complete and methodical investigation of the intermediate circum- 
stances which mark the passage of the Bath and Dundry beds into 
those of the Cotteswold series, so as to ascertain how far, and to 
what extent the division of the latter series into different stages, 
characterised by special Brachiopods, can be maintained over a more 
extended area; or whether such subdivisions are not of merely local 
value, and, in that respect, rather an hindrance than an aid when 
applied to the definition of beds, in the deposition of which different 
circumstances have in all probability prevailed.
