 thickness of the Oolites under Netheriield. '

The Introductory Chapter gives a general description of the different 

 members of the Secondary Series, as exhibited in traversing England 

 from Devon to Yorkshire. The physical geography of the Cam Valley 

 is next briefly indicated, from the sources of the river to its union with 

 the Ouse in the Fens. The deposits which occur within the limits of 

 sheet 51 of the Ordnance Survey Map are then described, beginning 

 with the Oxford and Kimmeridge Clays, with the subordinate calcareous 

 bands of St. Ives and Elsworth, and the local exposure of Coral Eag at 

 Upware. This last division is apparently absent in other parts of the 

 country, and seems here to have formed a coral island, against which 

 the Neocomian and Gault are banked up. The "Neocomian Sands, which 

 stretch from Sandy and Potton to Ely, are next noticed ; and above 

 these comes the Gault, of which the best section is at Barnwell. An 

 account of the Cambridge Greensand or Coprolite-bed, its constitution, 

 origin, and contents, is then given ; regarding the last, Mr. Bonney has 

 long maintained that they have been derived from the erosion of the 

 Gault. The Greensand passes above into the Chalk Marl or Clunch, as 

 it is locally termed, which is briefly described. Lastly, the Post-plio- 

 cene deposits are treated of under the following heads : — Boulder Clay, 

 Coarse Hill Gravel, Eine Gravel of the Plains, Older Peat, Buttery Clay, 

 and Newer Peat. In the Appendices are details of the Sections at 

 Upware, Ely, and Hunstanton ; also a few notes on the Water Supply 

 and Building Stones of Cambridge. A. J. J-B.
