1857.] PHILLIPS ESTUARY SANDS, SHOTOVER. 241 



from Kimmeridge Clay well characterized by fossils. On the Kim- 

 meridge Clay, about a mile to the north-east, Iron-sands are seen to 

 rest ; a little further, in the same direction, Portland-beds come be- 

 tween the Kimmeridge Clay and the Iron-sands, and the series of 

 Shotover is complete. In the district between Swindon and Ayles- 

 bury the strata between Oxford Clay and Gault are subject to irre- 

 gularity of thickness and local discontinuity ; in a general sense they 

 may be said to overlap to the north-east, in which direction the 

 Calc-grit, Oxford Oolite, Kimmeridge Clay, and Portland-rock dis- 

 appear one by one, but the Iron-sands are continuous. It is to be 

 hoped that the Geological Survey, in its progress to the north-east, 

 will furnish new data, and especially additional evidence from organic 

 remains, for the determination of the physical condition of this region 

 in the later Oolitic period. I regard it, however, as certain, that 

 much of the so-called " Iron-sand " on the northern outcrop of the 

 London Basin must be ranked among estuarine deposits.
