are given by himself, Sir A. Eamsay, Messrs. Dalton, Topley, Sharp, 

 Hudleston, Blake, Damon, Weston, and Bristow. The table on 

 p. 286, showing the subdivisions of the Lower Oolitic rocks, may 

 not meet the views of every geologist ; but at any rate it grapples 

 with a very dijBficult piece of correlation throughout this variable 

 series in different parts of England. The Middle and Upper Oolitic 

 beds are also very fully treated. 



The Cretaceous occupy rather over 70 pages, and include sections 

 by the author, Messrs. Topley, Bristow, Prestwich, Whitaker, 

 Strahan, Hughes, and Dowker. The following are the divisions 



adopted :

It is almost unnecessary to add that both as regards lithology 

 and paleeontology this system is most thoroughly dealt with ; the re- 

 searches of Dr. Hinde meet with frequent mention, and in addition 

 to the names already quoted in this connection we find those of 

 Messrs. Price, Meyer, Penning, Jukes-Browne, Barrels, and many 

 others. As regards the Chalk itself there is a table (pp. 402, 403) 

 showing the distribution of life zones in Yorkshire, Norfolk, Cam- 

 bridgeshire, Bedfordshire, Surrey, Kent, and the Isle of Wight. 

 The determination of these zones is due, he says, to the researches 

 of Prof. Hebert and Mr, Caleb Evans, and particularly of Dr. C. 

 Barrels. These have been followed out in various parts of England 

 by several geologists. " But Mr. Whitaker has remarked that 

 although they are very valuable when applied to particular sections, 

 yet their application to great inland stretches of country without 

 continuous sections, and when the structure of the deposits could be 

 seen only in occasional pits, was by no means safe." As a surveyor, 

 always on the look out for a feature, Mr. Whitaker prefers lithological 

 divisions such as the Chalk Kock, the Melbourn Eock, and the 

 Totternhoe Stone, which themselves appear to mark certain zones for 

 a considerable distance. 



Pakt III. CcENozoio. — This is divided into Tertiary and Quater- 

 nary. The Tertiary rocks include all, from the Thanet Sands to 

 the Cromer Forest Bed inclusive, and are illustrated by sections 

 from the author and Messrs. Whitaker, Bristow, Holmes, and 

 Prestwich. The Quaternary he divides into Pleistocene and Eecent. 

 " The Pleistocene period, so named by Lyell in 1830, includes 

 Terrestrial, Alluvial, Estuarine, Marine, and Glacial accumulations ; 

 and the organic remains found in certain Caverns and Eiver-deposits, 

 being associated with relics of Palgeolithic Man, these deposits are 

 sometimes regarded as of Paleeolithic age." Then follows a list of 

 the Mammalia characteristic of the Pleistocene Beds such as Ovibos 

 moschatus, Bison priscus, etc. The Glacial Beds are illustrated by 

 sections from the author. Sir A. Eamsay, and Messrs. De Eance, 

 Mellard Eeade, Ussher, Searles Wood, Lamplugh, Jukes-Browne,
