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 pre- 

 sent volume are tabulated on the following page, for the 

 convenience of those interested in the subject, 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 Ger- 

 man 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 half 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 is now 

 preparing by the same author from the present volume. 

 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 Eussian editions from the second English edition, 

 and the Swedish from the fifth English edition.
