tive of Geology. By Sir Charles Lyell, Bart. Illustrated 



with Maps, Plates, and Woodcuts. Two vols., royal 8vo. 



Cloth, $8.00. 



The " Principles of Geology " may be looked upon with pride, not only as a repre- 

 sentative of English Science, but as without a rival of its kind anywhere. Growing in 

 fullness and accuracy with the growth of experience and observation in every region ot 

 the world, the work has incorporated with itself each estahlished discovery, and has 

 been modified by every hypothesis of value which has been brought to bear upon, or 

 been evolved from, the most recent body of facts. 



^HE AUTOBIOGRAPHY OF THE EARTH: 



-* A Popular Account of Geological History. By Rev. H. N. 

 Hutchinson, B. A.,F. G. S. With 27 Illustrations. Crown 

 8vo. Cloth, $1.50. 



** A scientific work, divested of technicalities, and put into a bright, narrative form 

 wrhich can not but attract even the most general reader." — Boston Transcript. 



** It is hardly conceivable that the rich results of the science of geology can be so 

 treated as to prove uninteresting to thinking people, be they young or old. When, 

 therefore, we say that Mr. Hutchinson's book is extremely interesting, no more might 

 be implied than that the author has skillfully used the vast materials at his hand. But 

 Mr. Hutchinson has successfully carried out a difficult design nn an admiiable p!an> 

 and has adhered to that plan throughout His sketch of historical geology has a 

 g;enuine continuity." — Saturday Revieiv.
