Hew York Sun: " A charming book . . . showing; that the 

 greatest learning can be combined with the utmost simplicity 

 ... a book of intense interest. . . . The pictures are skillfully 

 arranged to elucidate the text " 



The London Times: " There has been published no book 

 on this subject combining so successfully the virtues of accu- 

 racy and attractiveness. . . . Dr. I.ankt-sier's methods as an 

 expositor are well known, but they have never been more 

 pleasantly exemplified than in the present book."

New York Times Review: "^n impressive statement of 

 human progress in knowledge and power by a conservative 

 scientist. ... It gathers into a very small compass and pre- 

 sents sharply to the layman an immensely impressive set of 

 facts and ideas." 



Outlook: lt A valuable addition to popular scientific litera- 

 ture.""
