MK. L. KICHAEDSON OX THE INFERIOR OOLITE [Nov. I907, 



that around that centre the transgression of the Upper Trigonia- 

 Grit across the outcrop-edges of successively-older beds is not so 

 regular as might be supposed from the foregoing remarks ; but, in 

 the main, that is the relationship of the ' grit ' to the underlying 

 beds. 



Throughout the district dealt with, except, of course, where it has 

 been removed by denudation in comparatively-recent times, the 

 Inferior Oolite is succeeded by the Fullers' Earth. My attention 

 being directed to the Pullers' Earth only when that deposit capped 

 the Inferior-Oolite sections with which I was dealing, it follows that 

 my researches in connexion therewith were far from exhaustive. 

 So far as they went, however, they tended to show that there was 

 no reason to suspect any overlap of the higher divisions when traced 

 from south to north. 



II. Subdivisions recognizable in the Inferior Oolite of the 

 Bath-Dotjlting District. 



The subdivisions recognizable in the Inferior Oolite of this district, 

 together with the fossils which Mr. E. Talbot Paris and I collected 

 from them, are shown in Table YI (facing p. 436); the micro-fauna 

 of the Upper Coral-Bed, worked out by Mr. C. Upton, in Table IV 

 (p. 413) ; and the fossils of the Fullers' Earth in Table VII (facing 

 p. 436). 



Prom Table I (below) it will be seen that, including the Upper 

 Trigonia-Grit, six subdivisions of the Inferior Oolite can be 

 recognized. Their equivalent beds in the Stroud and Cheltenham 

 districts are also indicated.
