story of a man whose well was 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 quarry man : 



Kubbly beds 4 feet. 



Hard gritty rock 9 



Freestone beds 6 



Hard coarse freestone 3 



Rubbly stone 8 or 9 



Shelly-bed, containing Trigonia and Spinosa . .3 



Blue Clay 4 or 5 



Sand 



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.
