288 Revieivs—E. T, Stevens's" Flint Chips." 



nation has — so far as we are aware — arrived at the bronze or iron 

 age save by gradual advancement in the ruder and simpler arts of 

 savage life. 



The absence of metals in one region may have effectually checked 

 their use, whilst in another they may have been discovered and 

 worked from a very remote antiquity. 



Viewed by the light afforded by such a collection as that contained 

 in the Blackmore Museum — so ably and industriously illustrated and 

 described by its Honorary Curator in the work before us — we are 

 more strongly than ever impressed by the necessity of asking for 

 greatly increased grants of time in order that the distribution and 

 development of the human race should take place — as we know it 

 must have done — very gradually, especially the earlier stages, such 

 as this book is intended to illustrate. 



A copious index is given, and the objects treated of are rendered 

 even clearer still by the addition of 125 illustrations distributed 

 through the text, and also by a plate of flint implements from 

 Honduras, certainly the most remarkable heretofore seen. 



The illustrations by Mr. Gr. E. De Wilde, are executed with great 

 care and fidelity. 



n. — Geological Map of London, showing Superficial Deposits. 

 Compiled by J. B. Jordan, Esq., of the Mining Eecord Office, 

 from the Published Maps and Memoirs of the Geological Survey 

 of England and Wales, and from the Maps and Memoir ac- 

 companying " Eeports of the Medical Officer of the Privy Council, 

 1866 to 1867," by E. W. Mylne, Esq., and W. Whitaker, Esq., 

 B.A. Scale, one inch to a mile. London : E. Stanford. 



THE comjDiler of this map has been diligent in the library, and 

 has shown great aptitude in the performance of certain pro- 

 cesses of digestion and assimilation. Is it possible that the mere 

 consultation of the "Eeports of the Medical Officer of the Privy 

 Council " can have enabled him thus to triumph over the toughness 

 of food utterly raw — entirely uncooked ? Our own sad experience 

 would have led us to predict a violent attack of dyspepsia, and our 

 "Medical Officer " would have advised a walk into, let us say, that 

 great north-western region which is so monotonously depicted as " a 

 stiff blue clay impervious to water." In the interests of the pur- 

 chasers of this map, we are led to exclaim. Would that Mr. Jordan 

 were dyspeptic ! Just one " Journey due North " would have im- 

 bued him with a wholesome scepticism, and would probably have 

 led to the publication of a map which might more justly lay claim 

 to the title of a " Geological Map, of London, showing superficial 

 deposits."
