PREFACE TO THE NINTH EDITION. 



IN this edition several corrections and additions, ren- 

 dered necessary by the progress of discovery, have 

 been introduced into the text, and notes have been 

 added with reference to other new points. The 

 general statements and conclusions remain, however, 

 substantially the same as in 1873; the author having 

 seen no valid reason to depart from any of them, 

 while with respect to some, additional evidence in 

 their favour has been furnished by the facts and dis- 

 cussions developed in recent years. 



More full discussion of the Harmony of Geology 

 with Revelation, and of the characters and conditions 

 of Primitive Men, will be found in the author's more 

 recent works, " The Origin of the World " and 

 " Fossil Men."
