312 Reviews — LyeWs Antiquity of Man. 



Western coal-field will hardly exceed 1000 feet, and in Indiana 

 not more than 700 feet. 



The intercalated limestones and shales are replete with marine 

 remains of fish, Cephalopods, Brachiopods, and Gasteropods, many 

 of them even being specifically identical with British Carboniferous 

 forms, an occurrence " which can scarcely be harmonized with the 

 adopted ' bog or swamp ' theory for the deposition of Coal and Coal- 

 measure Limestones ; " (p. 200) " for they indicate a home in the pro- 

 found and quiet depths of a central ocean, remote from the influence 

 of waves as well as from rocky or sandy bottoms, until some mighty 

 current of disturbed and muddy waters, impelled by earthquake 

 action, overwhelmed these animals — the impure water putting an 

 end to their life, and burying them in the slimy bed deposited over 

 the coal material." (Eeport, 1872, p. 201.) 



These two volumes, which are chiefly occupied by descriptions of 

 the Carboniferous rocks, contain also some useful and interesting 

 notices of the Quaternary deposits, as well as of the agriculture^ 

 botany, and economical substances of the districts surveyed.

I. — The Geological Evidences of the Antiquity of Man ; with 

 AN Outline of Glacial and Post-Tertiary Geology, and 

 Remarks on the Origin of Species, with special reference 

 to Man's First Appearance on the Earth. By Sir Charles 

 Lyell, Bart., M.A., F.R.S. Fourth edition, revised. 8vo. pp. 

 572. (London : John Murray, 1873.) 



"l^TO man, during a long career as a scientific writer, has ever 

 Aji enjoyed a more well-deserved popularity or held a higher 

 position as the exponent of modern geological thought and discovery 

 than Sir Charles Lyell. 



His books have been widely circulated and largely read. Even his 

 " Antiquity of Man " — to some extent a diversion from his previous 

 writings, and forming as it were an advanced post in a new region 

 (the Quaternary Period) about to be annexed to Geological Science — 

 met with the same warm and ready reception by the public. 



Thus we find that the first edition, which was published in 1863, 

 was followed by the second two months later, and by the third edition 

 before the end of the year ! Such a run of popularity required an 

 interval of rest and recuperation ; accordingly we find a period of 

 ten years has now elapsed since the publication of the third edition 

 — a period rich in varied and additional proofs of Man's antiquity. 

 These, so far as the author has been able to collect and compress them 

 into the small number of pages added to the fourth edition, will 

 be found duly arranged and enrolled in the present volume. 



The author has divided his book into three distinct parts, the first 

 of which, called the ''Antiquity of Man," might with more propriety 

 (he thinks) have been distinguished as the " Geological Memorials of 

 Man." The introduction, into the second part, of "the Glacial
