Reviews — Dixon's Geology of Sussex. 523 



Mr. E. T. Newton, F.G.S., who have added mucli valuable additional 

 matter to this section of the work. 



Professor Owen has revised the Reptilian portion throughout, and 

 added a note on Iguanodon (p. 428). 



The Antiquities — both Historic and Pre-historic — have been care- 

 fully revised, and also somewhat added to. The Coins, etc., by 

 Dr. J. Evans, F.R.S., and C. Roach-Smith, Esq., F.S.A. Whilst the 

 discovery of a Palseolithic implement at Portslade, and an account 

 of the Sussex Hill-Forts and Flint-implement Factory at Cisbury, is 

 given by Mr. Ernest H. Willett, F.S.A. 



The weakest part of tbe original work was probably the geology. 

 This is now entirely obviated. The opening chapter gives an ex- 

 cellent and clearly-written account of the general geographical and 

 geological features of the County of Sussex by tbe Editor, Professor 

 T. Rupert Jones, F.R.S. ; illustrated by a charming map of the 

 County coloured geologically (measuring 28in. by lOin.), with a 

 section from the English Channel to the Isle of Sheppey, by W. 

 Topley, F.G.S. 



The Newer Tertiary, Post-Tertiary, or Quaternary beds of Sussex 

 are fully described after Godwin-Austen, Prestwich, Mantell, Bell, 

 and others. 



The Tertiary beds of Bracklesham, etc., in addition to F. Dixon's 

 description, have added to them the accounts of Dr. Bowerbank 

 and the Rev. 0. Fisher, M.A., F.G.S. 



The Newhaven Beds are described after Professor Prestwich, 

 F.R.S., and Mr. W. Whitaker, B.A., F.G.S. 



The chapters on the Chalk Formation have been entirely revised 

 and modified according to our present knowledge. 



The description of the Wealden and other strata of East Sussex 

 forms an entirely new chapter : whilst Mr. Topley's account of the 

 Sub- Wealden trial boring, and its results to science, will form a 

 permanent memorial of that interesting attempt to solve the geologi- 

 cal structure at the base of the Wealden series. Besides the large 

 number of entirely new chapters which have been added to the 

 work, no page can be referred to which has not been enriched by 

 some new facts carefully and correctly placed by the judicious 

 Editor. Every author writing on subjects bearing upon the geology 

 or palseontology of Sussex since 1850, will be gratified to find his 

 observations quoted in their appropriate chapter ; whilst the copious 

 index renders the woi'k at once easy and convenient for reference. 



The Editor, in every case, marks new matter added, giving the 

 authority cited, and so careful has he been, that even a word 

 inserted is put into square brackets to show that it is new. 



We may fairly congratulate Mr. William J. Smith, the Brighton 

 publisher, who has ventured upon the undertaking of this New 

 Edition of " Dixon's Geology of Sussex," and we can but hojoe that 

 the task so ably carried to its completion by Professor T. Rupert 

 Jones may be appreciated by a large circle of geological friends, not 

 only in the County of Sussex, but throughout Great Britain and 

 abroad, among the many foreign geologists who take a lively interest 

 in English scientific literature. W^.
