KEW GEOLOGICAL MAP OF THE NEIGHBOURHOOD OF OXFOED. 



On Saturday the 30th June, Sir R. I. Murchison drew the attention of the 

 Section to the maps of the neighbourhood of Oxford just completed by the 

 Geological Survey, and accompanied by explanatory memoirs. The area em- 

 braced the \vhole series of formations from the "Woolwich and Beading series" 

 of the Tcrtiarv system (Prestwich) to the Lower Lias, and included the towns 

 of Banbury, \\'oodstock, Earriiigdon, AYantage, Thame, with Oxford about the 

 centre (sheets 13, 15 south-west, 45 north-west). This district had been sur- 

 veyed by Messrs. Hull, Whitaker, Polwhele, and Bauerman. 



Mr. Hull then proceeded to give a rapid sketch of the most interesting 

 points recorded in the maps, dwelling particularly on the iron-producing beds 

 of the Lias, the fragmentary distribution of the Portland and Lower Cre- 

 taceous groups, particularly the sponge -gravels of Earrmgdon. With reference 

 to the fresli-watcr ii-on-sands of Shot over Hill, it was shown that thev were 

 cntiroly isolated from the marine beds of the Lower Greensand period,' which 

 range from Culham by Xuneham to Tool-Baldon. After much consideration, 

 it was deemed tlie less hazardous course to colour the fresh-water beds of Shot- 

 over as Lower Greensand, under the supposition that thcv mav be an estuarine 

 ami marginal portion of that formation. At the same time, recollecting
