We remark in passing that the Laurentian eozoonal limestone is 

 placed with rock-salt and gypsum in the Homokokkite division, 

 from which we presume that the author is at least convinced of the 

 inorganic nature of this rock, though his statement respecting it is 

 not very explicit (see p. 97). G. J. H. 



II. — Geological Survey Publications. 



1. — Guide to the Geology of London and the Neighbourhood. 



By William Whitaker. Fourth Edition, 1884:, pp. 89. 



Price Is. 

 This is undoubtedly one of the most successful publications issued 

 by the Geological Survey of England and Wales ; for no other 

 memoir of the Survey has reached even a third edition. Tho 

 " Guide to the Geology of London " has been published at a much 

 lower price than the majority of the Survey Memoirs ; it is printed 

 in large type (though with indifferent ink), and above all it is 

 written in a concise and readable style. The chief points in which 

 this edition differs from the last are noted by Mr. Whitaker in his 

 preface. Most important are the accounts of recent deep borings, 

 especially that at Eichmond ; while the generalized section across 

 the London Basin, showing the underground range of old rocks, 

 has been modified in accordance with the fresh data furnished by the 

 borings. Sections are also given of the Lower London Tertiaries, 

 north and south of the Thames. 



In another edition it would be useful to give the species as well 

 as the genera of the commoner fossils that are met with ; and perhaps 

 an index-maj) might be furnished, after the plan adopted in the 

 Explanation of Sheet 13, and some other Memoirs.
