PREFACE TO THE SECOND EDITION, 



TN preparing a New Edition of PEE-HISTOEIC TIMES, 

 I have endeavoured, as far as possible, to avoid 

 unduly increasing the size of the book ; and although 

 the present "Work will be found to contain a great 

 number of new facts, some of the chapters being indeed 

 almost re-written, still it is only increased in size to 

 the extent of one hundred pages. Nearly half of these 

 are occupied by the addition of more than seventy 

 new figures, which will tend to diminish, rather than 

 increase, the time occupied by its perusal. 



This course has compelled me to omit all reference 

 to many researches of much merit and interest, while 

 in other cases I have been obliged to treat the labour 

 of years in a few short sentences. The true force of 

 the evidence in support of archaeological conclusions 

 is thus materially weakened, by being deprived of its 

 cumulative character ; but I have endeavoured in many 

 cases to meet this objection by the introduction of 

 statistical tables.
