of different members of the Lower Oolites, and of the different 

 conditions which prevailed in closely adjoining areas. The great 

 sandy series, which had unfortunately been correlated as a whole 

 with the Northampton Sand of the Midlands, appeared to include 

 representatives of both the Great and the Inferior Oolites. 



Mr. Etherldge thought it very difficult to correlate these beds of 

 the Chipping-Norton area with those of the Cotteswold Hills. He 

 remarked upon the remarkable attenuation of the Inferior Oolite 

 when traced into the neighbourhood of Bridport. He considered 

 the working-out of the minute geology of local areas would furnish 

 a key to many difficult problems. 



Mr. Baeerman stated that he had himself drawn the lines in the 

 district represented in the author's map, the work in the remainder 

 of the sheet having been carried on by Mr. Polwhele. He had 

 then assigned the beds to the Inferior Oolite. 



Mr. Waleoed stated that his map and the whole of his work had 

 been based on the publications of the Geological Survey. Some 

 artificial openings he had recently made confirmed his views on the 

 succession of beds in the area. Even if some of the beds were equi- 

 valent to the Euller's Earth, these are, as Professor Tate showed, 

 referable to the Inferior rather than to the Great Oolite.
