ADDITIONS AND CORRECTIONS 



TO THE SIXTH EDITION. 



NUMEROUS small corrections have been made in the last and 

 present editions on various subjects, according as the evidence 

 has become somewhat stronger or weaker. The more important 

 corrections and some additions in the present volume are tabu- 

 lated below, for the convenience of those interested in the sub- 

 ject, and who possess the fifth edition. The second edition was 

 little more than a reprint of the first. The third edition was 

 largely corrected and added to, and the fourth and fifth still more 

 largely. As copies of the present work will be sent abroad, it 

 may be of use if I specify the state of the foreign editions. The 

 third French and second German editions were from the third 

 English, with some few of the additions given in the fourth edition. 

 A new fourth French edition has been translated by Colonel 

 Moulinie ; of which the first naif is from the fifth English, and 

 the latter half from the present edition. A third German edition, 

 under the superintendence of Professor Victor Carus, was from 

 the fourth English edition ; a fifth, by the same author, from the 

 sixth edition. The second American edition was from the English 

 second, with a few of the additions given in the third; and a 

 third American edition has been printed from the fifth English 

 edition. The Italian is from the third, the Dutch and three 

 Russian editions from the second English edition, and the 

 Swedish from the fifth English edition.
